feat(security): harden puzzle layer params (n=128, m=192) #72
Conversation
- Update Rust generator to use secure entropy (OsRng) for LWE/Puzzle noise - Refactor to accept external RNG - Update Benchmark script to use separate noise seed with warning - Add task documentation for Issue #65 fix
- Increases standard deviation from 8.0 to 25.0 - Enhances resistance against lattice reduction attacks - Error margin (4*sigma = 100) is still well below threshold (16380) - No impact on gas costs or storage size
- Increase puzzle dimension n from 48 to 64 - Increase samples m from 72 to 96 - Brute-force space increases from ~2^76 to ~2^101 - Mitigation against BKW/Lattice reduction attacks identified in review - Gas cost increase: ~30% (verified in tests)
- Increased LWE noise sigma from 8 to 25 for ~2^112 PQ security - Increased Puzzle dimension n from 48 to 64 (~2^101 one-time floor) - Added critical security warnings to contracts regarding secret noise generation - Updated papers (tlos.tex, tlos-paper.tex) to reflect new parameters and security model - Updated AGENTS.md with current configuration

22-25: Parameters not updated to match the PR's hardened values.The constants still use the old puzzle parameters (N_WEAK=48, M_WEAK=72, PUZZLE_THRESHOLD_SQ=300), but this PR hardens them to n=64, m=96, and threshold=400. Based on learnings, production Layer 4 puzzle must use n=64, m=96, threshold=400.
Proposed fix
- uint256 public constant N_WEAK = 48; - uint256 public constant M_WEAK = 72; + uint256 public constant N_WEAK = 64; + uint256 public constant M_WEAK = 96; uint256 public constant Q_WEAK = 2039; - uint256 public constant PUZZLE_THRESHOLD_SQ = 300; + uint256 public constant PUZZLE_THRESHOLD_SQ = 400;
48-48: Array sizes must be updated to 64 to match the new N_WEAK parameter.All function signatures and local arrays use hardcoded size
[48], which is inconsistent with the intended N_WEAK=64. The loop generalization (blocks = (N_WEAK + 15) / 16) is correct, but the array dimensions need to match.Proposed fix for function signatures and arrays
- function recover(bytes32 phrase, int8[48] calldata puzzleSolution) external { + function recover(bytes32 phrase, int8[64] calldata puzzleSolution) external {- function checkRecovery(bytes32 phrase, int8[48] calldata puzzleSolution) + function checkRecovery(bytes32 phrase, int8[64] calldata puzzleSolution)- function getPlantedSecret(bytes32 x) external pure returns (int8[48] memory secret) { + function getPlantedSecret(bytes32 x) external pure returns (int8[64] memory secret) {- function _verifyPuzzle(bytes32 x, int8[48] calldata solution) + function _verifyPuzzle(bytes32 x, int8[64] calldata solution)- int16[48] memory planted; + int16[64] memory planted;Also applies to: 65-65, 83-83, 105-105, 119-119
11-11: Security figure in comment needs update.The comment states "~76 bits of computational work" which reflects the old n=48 parameters. With the hardened n=64 parameters, this should be updated to ~101 bits to match the 3^64 ≈ 2^101 brute-force floor.
Proposed fix

54-57: Critical: Puzzle parameters not updated to new hardened values.The constants still use the old parameters (n=48, m=72, threshold=300), but this PR's objective is to harden them to n=64, m=96, threshold=400. The blocks-based loop generalization was applied without updating the underlying constants, causing inconsistency with the production contracts.
Based on learnings, Production Layer 4 puzzle must use: n=64, m=96, q=2039, threshold=400.
Proposed fix
- uint256 public constant N_WEAK = 48; - uint256 public constant M_WEAK = 72; + uint256 public constant N_WEAK = 64; + uint256 public constant M_WEAK = 96; uint256 public constant Q_WEAK = 2039; - uint256 public constant PUZZLE_THRESHOLD_SQ = 300; + uint256 public constant PUZZLE_THRESHOLD_SQ = 400;
141-141: Array size mismatch: should beint8[64]to match updatedN_WEAK.When constants are updated to N_WEAK=64, the function signature must also change to
int8[64] calldata puzzleSolution. The same applies togetPlantedSecret(line 214),_verifyPuzzle(line 248), and the internalplantedarray (line 262).
19-22: Documentation still references old parameters.The comments describe n=48 and 3^48 ≈ 2^76, but should be updated to n=64 and 3^64 ≈ 2^101 to match the PR's security hardening objective. Similar updates needed at lines 140, 236, and 240.
examples/TLOSDeadManSwitch.sol (3)
89-94: Critical: Puzzle parameters not updated to new hardened values.Same issue as in
TLOSTreasureHunt.sol- the constants still use old parameters (n=48, m=72, threshold=300) instead of the hardened values (n=64, m=96, threshold=400). Based on learnings, this must be updated for consistency with production contracts.Proposed fix
uint256 public constant COMMIT_DELAY = 2; - uint256 public constant N_WEAK = 48; - uint256 public constant M_WEAK = 72; + uint256 public constant N_WEAK = 64; + uint256 public constant M_WEAK = 96; uint256 public constant Q_WEAK = 2039; - uint256 public constant PUZZLE_THRESHOLD_SQ = 300; + uint256 public constant PUZZLE_THRESHOLD_SQ = 400; bytes32 public constant PUZZLE_DOMAIN = keccak256("TLOS-PlantedLWE-v7");
291-295: Array sizes must be updated to[64].The
claimfunction signature at line 294 usesint8[48], but this must beint8[64]to match the updated N_WEAK. Same applies togetPlantedSecret(line 390),_verifyPuzzle(line 421), and the internalplantedarray (line 435).
26-28: Documentation references outdated security parameters.The documentation still describes "3^48 ~ 2^76" floor. Should be updated to "3^64 ~ 2^101" to match the hardened parameters. Similar updates needed at lines 290 and 420.
examples/TLOSSealedAuction.sol (5)
57-65: Example contract parameters are inconsistent with production WeakLWEPuzzleV7.The constants claim to match
WeakLWEPuzzleV7(line 57) but use outdated values:
N_WEAK = 48should be64M_WEAK = 72should be96PUZZLE_THRESHOLD_SQ = 300should be400This creates a mismatch with production contracts and could mislead developers copying from examples. Either update to match production or add clear documentation that this example intentionally uses legacy/smaller parameters for demonstration.
Option A: Update to match production (recommended)
- uint256 public constant N_WEAK = 48; - uint256 public constant M_WEAK = 72; + uint256 public constant N_WEAK = 64; + uint256 public constant M_WEAK = 96; uint256 public constant Q_WEAK = 2039; - uint256 public constant PUZZLE_THRESHOLD_SQ = 300; + uint256 public constant PUZZLE_THRESHOLD_SQ = 400;Option B: Document legacy parameters (if intentional)
// ========================================================================= // CONSTANTS - Puzzle Parameters (matching WeakLWEPuzzleV7) + // NOTE: This example uses LEGACY parameters (n=48, m=72) for lower gas costs + // in demonstrations. Production uses n=64, m=96 (see WeakLWEPuzzleV7.sol). // =========================================================================
209-213: Function signature uses legacy 48-element array.The
revealBidfunction acceptsint8[48]but productionWeakLWEPuzzleV7now usesint8[64]. This needs to match the constants update.function revealBid( uint256 bidAmount, - int8[48] calldata puzzleSolution, + int8[64] calldata puzzleSolution, bytes32 salt ) external inPhase(AuctionPhase.REVEAL) {
394-408: Documentation comments reference outdated dimensions.Lines 400-402 describe "Matrix A (72x48 over Z_2039)" and "||A*s - b||² < 300" which need updating to match the new parameters (96x64 and threshold 400).
- /// Technical details (matching WeakLWEPuzzleV7): - /// - Matrix A (72x48 over Z_2039) derived from keccak256 - /// - Target b = A*planted + e where e in {-2,-1,0,1,2} - /// - Valid solution s: ||A*s - b||² < 300 + /// Technical details (matching WeakLWEPuzzleV7): + /// - Matrix A (96x64 over Z_2039) derived from keccak256 + /// - Target b = A*planted + e where e in {-2,-1,0,1,2} + /// - Valid solution s: ||A*s - b||² < 400
408-422: Internal function signature also needs updating.The
_verifyPuzzlefunction acceptsint8[48]and theplantedarray isint16[48]. These should be updated to 64 elements.- function _verifyPuzzle(bytes32 seed, int8[48] calldata solution) + function _verifyPuzzle(bytes32 seed, int8[64] calldata solution) internal pure returns (bool valid, bytes32 sHash) { // ... - int16[48] memory planted; + int16[64] memory planted;
18-23: Update security claim in NatSpec comments.Line 21 states "3^48 ≈ 2^76" which is outdated. If updating to production parameters, this should be "3^64 ≈ 2^101".
test/PuzzleVariants.t.sol (1)
7-9: Stale NatSpec comment references old parameters.Line 8 states "(n=48, m=72, 2^76 security)" but the tests now verify (n=64, m=96, 2^101 security).
/// `@title` Puzzle V7 Test -/// `@notice` Tests the production puzzle version V7 (n=48, m=72, 2^76 security) +/// `@notice` Tests the production puzzle version V7 (n=64, m=96, 2^101 security) contract PuzzleV7Test is Test {

In `@README.md`:
- Line 16: Update the inconsistent gas figure in the README: replace the
"~2.25M" gas note in the "Planted LWE puzzle" line (the text containing "3^64 ≈
2^101 floor for recovering the planted solution without enumeration") with
"2.30M gas (Tenderly, production-style)" so it matches Line 143 and the
documented learnings.
In `@test/PuzzleVariants.t.sol`:
- Around line 18-25: The section comment above test_V7_Parameters still shows
the old parameters; update that comment to reflect the new production values
(n=64, m=96, q=2039, THRESHOLD_SQ=400) so it matches the assertions that
reference puzzleV7.N_WEAK(), puzzleV7.M_WEAK(), puzzleV7.Q_WEAK(), and
puzzleV7.THRESHOLD_SQ().
🧹 Nitpick comments (2)
src/security/lattice_estimator.rs (1)
336-341: Consider adding a minimum expected bits assertion for puzzle.The test now only asserts
bits > 0(line 340), which is extremely permissive. While the comment correctly explains that the security model relies on the 3^64 brute-force space rather than lattice hardness, you might want to add a comment explaining why no lower bound is enforced, or consider documenting the expected lattice-estimator output range for regression detection.docs/layers/layer4-puzzle/README.md (1)
75-77: Gas estimate inconsistency with Tenderly benchmarks.Line 75 shows "~2.25M (estimate)" but the learning indicates "2.30M gas (Tenderly, production-style)" for the n=64/m=96 puzzle. Line 77 correctly notes the re-benchmark is pending. Once benchmarks are completed, update the estimate to match the actual measurement.

docs/layers/layer2-lwe/README.md (1)
11-11: LGTM! Documentation correctly updated to reflect σ=25.The Layer 2 LWE noise parameter update from σ=8 to σ=25 is consistent with the production LWE layer requirements and aligns with the broader parameter hardening in this PR. Based on learnings, production LWE layer must use σ=25.
Also applies to: 26-26
src/lib.rs (1)
8-8: LGTM! Module documentation accurately reflects the hardened parameters.The puzzle floor update to 3^64 ≈ 2^101 and LWE σ=25 are consistent with the PR objectives and production requirements. Based on learnings, these values align with the five-layer security model.
Also applies to: 13-13
scripts/attacks/README.md (1)
11-11: LGTM! Attack documentation updated with correct hardened parameters.Layer 4 puzzle references consistently updated to n=64 and 3^64 ~ 2^101 brute-force floor across directory listing, section header, and key results. As per coding guidelines, attack scripts are properly organized by layer in the scripts/attacks/ directory structure.
Also applies to: 56-56, 79-79
docs/wire-binding.md (1)
67-67: LGTM! Gas cost figures updated consistently across the document.The updated gas measurement of 18,184,574 for 640 gates (30% of 60M block) aligns with the Tenderly benchmarks mentioned in the PR objectives and matches the learnings for TLOS gas usage with n=384.
Also applies to: 113-113, 120-120
examples/TLOSRecovery.sol (1)
87-97: Loop generalization pattern is correct and future-proof.The dynamic block computation
blocks = (N_WEAK + 15) / 16with retained bounds checks (idx >= N_WEAK,col >= N_WEAK) is well-implemented. Once the constants are updated to N_WEAK=64, this will correctly process 4 blocks of 16 elements each.Also applies to: 122-134, 144-157
examples/TLOSTreasureHunt.sol (1)
218-228: Loop generalization is correct.The blocks-based iteration with
blocks = (N_WEAK + 15) / 16correctly computes ceiling division for 16-element chunks. The break conditions properly handle partial final blocks. Once the constants are updated, this code will work correctly for n=64.src/bin/generate_tlos.rs (1)
29-30: LGTM: Secure RNG usage for production CLI.Using
rand::thread_rng()is appropriate here as it provides cryptographically secure randomness from the OS. This aligns with the PR's objective to decouple LWE noise generation from public seeds.examples/TLOSDeadManSwitch.sol (1)
394-404: Loop generalization correctly implemented.The blocks-based iteration pattern is correct. Once the constants are updated to n=64, this will work as expected.
src/generator.rs (3)
22-32: LGTM: Well-designed RNG API refactor.The generic RNG parameter design is clean:
- Documentation clearly states RNG must be cryptographically secure for production
- Generic bound
R: Rngallows flexibility for both secure (OsRng/thread_rng) and deterministic (seeded ChaCha) usage- Supports the PR's objective of decoupling LWE noise generation from public seeds
43-46: Correct RNG propagation.The RNG is properly passed to
encode_gate, which aligns with the updated signature insrc/lwe.rs. This ensures noise generation uses the externally provided RNG.
141-156: Excellent determinism test.The test properly verifies that identical RNG seeds produce identical deployment data, which is crucial for verifying the deterministic behavior of the generation process with externally-controlled RNG.
src/security/mod.rs (1)
5-6: Documentation correctly updated for hardened parameters.The comment accurately reflects the new security parameters: n=64 with a 2^101 one-time floor. This aligns with the PR objectives and retrieved learnings.
docs/reviewer-letter-lwe-fix.md (1)
3-4: LGTM!The production update notice correctly documents the parameter evolution (σ=25, 2^101 floor) while preserving the historical analysis context. This is good practice for maintaining audit trails of security decisions.
test/WeakLWEPuzzleV7.t.sol (1)
10-13: LGTM!The test correctly updates to 64-element planted secret arrays and the log message accurately reflects the new n=64, m=96 parameters. This aligns with the production Layer 4 puzzle specification. Based on learnings, the updated parameters ensure 3^64 ≈ 2^101 search space.
src/lwe.rs (2)
3-9: LGTM!The documentation accurately describes the LWE parameters and estimator inputs. The secret distribution (uniform mod q) and error distribution (rounded Gaussian) are correctly specified for lattice estimator analysis.
33-34: LGTM!The noise parameter update to σ=25 is correct per production requirements. The decryption margin remains safe: with 4σ=100 maximum expected error magnitude, the threshold of q/4=16380 provides ample separation for reliable decoding.
Based on learnings, this achieves ~2^112 PQ security with n=384.
docs/layers/README.md (2)
15-15: LGTM!The Layer 4 security floor update to 2^101 accurately reflects the expanded puzzle parameters (n=64, m=96). This aligns with the five-layer security model requirements from learnings.
30-30: LGTM!The Quick Reference table correctly documents the new 2^101 one-time puzzle floor.
test/TLOSWithPuzzleV5Harness.sol (1)
35-37: LGTM!The harness correctly exposes
_verifyPuzzlewith the matching signature from the parent contract, accepting 64-element solutions for Layer-4 isolated testing.src/security/lattice_estimator.rs (2)
246-263: Main LWE parameters correctly updated to σ=25.The parameter update from σ=8.0 to σ=25.0 aligns with the production LWE layer requirements. Based on learnings, production parameters should be n=384, σ=25, q=65521.
265-281: Puzzle parameters correctly updated to n=64, m=96.The documentation and function parameters align with the new Layer 4 puzzle specification (n=64, m=96, 3^64 ≈ 2^101 search space). Based on learnings, this matches production requirements.
docs/tasks/issue-65-secret-noise-fix.md (1)
1-54: Clear documentation of the noise generation vulnerability and remediation plan.The analysis correctly identifies that deterministic noise derivation from public seeds enables secret recovery via Gaussian elimination. The implementation plan appropriately separates public matrix generation from secret noise generation.
docs/layers/layer4-puzzle/README.md (2)
3-14: Parameter table correctly reflects hardened puzzle configuration.The documentation now accurately reflects n=64, m=96, threshold=400, and 3^64 ≈ 2^101 search space, which aligns with the production requirements from learnings.
79-84: Attack economics updated for 3^64 search space.The brute-force analysis correctly reflects the vastly increased search space. The astronomical time estimates (>10^14 years) accurately convey the impracticality of exhaustive search.
examples/TLOSSealedAuction.sol (1)
369-384: Loop generalization is correct but constants need updating.The dynamic
blocks = (N_WEAK + 15) / 16calculation is a good refactor for maintainability. With the currentN_WEAK=48, this evaluates to 3 (unchanged behavior). Once constants are updated to 64, this will correctly compute 4 blocks.test/PuzzleVariants.t.sol (3)
27-37: Test correctly validates planted secret with updated array size.The
int8[64]array size and_assertTernary64helper align with the new n=64 dimension. Gas logging correctly reflects the updated parameters.
69-73: Security level assertion correctly updated.The 3^64 ≈ 2^101.4 calculation is accurate, and the assertion
v7_bits >= 101properly validates the security target.
77-88: Helper functions correctly updated for 64-element arrays.The
_assertTernary64and_randomTernary64helpers properly iterate over 64 elements.README.md (1)
1-314: Documentation updates look good overall.The parameter updates (n=64, m=96, threshold=400, σ=25) are consistently applied throughout the README. Gas figures, security estimates, and deployment notes align with the PR objectives and retrieved learnings. Based on learnings, the new parameters ensure 3^64 ≈ 2^101 search space with 2.30M gas verification.
paper/tlos.tex (1)
1-502: Paper updates are consistent and well-formatted.The LaTeX formatting adheres to the coding guidelines (two-column conference style, correct geometry, proper lstset configuration). All parameter updates (n=64, m=96, threshold=400, σ=25, 2^101 floor, 2.30M gas) are consistently applied throughout the document. As per coding guidelines, the paper correctly uses
\ttfamily\scriptsizefor code listings.AGENTS.md (1)
1-178: Agent instructions correctly updated.All parameter updates are consistent: LWE layer (n=384, σ=25, ~2^112 PQ), puzzle layer (n=64, m=96, threshold=400, 2^101 security, 2.30M gas). The documentation structure and commands remain accurate. Based on learnings, these parameters align with the production requirements.
docs/security.md (1)
1-320: Security documentation comprehensively updated.All parameter changes are consistently reflected: puzzle dimensions (n=64, m=96), threshold (400), security floor (2^101), LWE noise (σ=25), and gas figures (2.30M puzzle, 4.7M-18.2M total). The code snippet correctly shows the updated
int8[64]signature. Based on learnings, the documented parameters match production requirements.contracts/WeakLWEPuzzleV7.sol (3)
4-15: Contract parameters correctly hardened.The constants are updated per the new security requirements: N_WEAK=64, M_WEAK=96, THRESHOLD_SQ=400. The threshold comment accurately reflects the expected squared norm calculation (E[||e||²] = 96 × 2 = 192), with 400 providing sufficient margin for valid solutions while rejecting random guesses. Based on learnings, these parameters ensure 3^64 ≈ 2^101 search space.
The warning about deterministic noise being cryptographically broken is important and correctly documented.
19-95: Verification logic correctly generalized.The implementation properly handles the increased dimensions:
- Block count dynamically computed as
(N_WEAK + 15) / 16 = 4blocks- Inner loops include bounds checks (
if (idx >= N_WEAK) break) to handle the exact dimension- Ternary validation (Lines 25-29) correctly validates all 64 elements
- Residual centering (Lines 79-84) correctly handles modular arithmetic wraparound
The use of
uncheckedis appropriate here since all arithmetic is bounded by the modulus operations.
97-112: Helper function correctly updated.The
getPlantedSecretfunction signature and implementation are consistent with the updated N_WEAK=64 dimension. The block-based generation logic mirrors the planted secret computation inverifyPuzzle, ensuring consistency.contracts/TLOSWithPuzzleV5.sol (4)
26-34: LGTM! Security documentation is well-structured.The updated parameters (σ=25 for LWE, n=64/m=96/threshold=400 for puzzle) align with the PR objectives. The critical security requirement note about noise entropy is an important addition—this correctly warns that Gaussian noise must not be derived from public seeds. Based on learnings, these are the correct production parameters for Layer 4 puzzle (2^101 search space).
42-45: Parameter updates correctly implement hardened puzzle layer.The constants align with the PR objectives and retrieved learnings:
N_WEAK = 64: brute-force floor now 3^64 ≈ 2^101 (up from 2^76)M_WEAK = 96: increased samples for improved lattice resistancePUZZLE_THRESHOLD_SQ = 400: calibrated for error in [-2,2] with larger dimension
235-254: Dynamic block processing correctly handles larger dimension.The generalized loop structure properly adapts to n=64:
blocks = (N_WEAK + 15) / 16computes ceiling division (yields 4 blocks)- Inner loop guards against out-of-bounds with
if (col >= N_WEAK) break- Coefficient extraction and dot-product accumulation are consistent with the previous implementation
128-128: Function signatures consistently updated for 64-element puzzle solution.All public and internal functions accepting puzzle solutions have been updated from
int8[48]toint8[64], maintaining API consistency across the contract.Also applies to: 163-163, 215-215
scripts/BenchmarkPuzzleV7.s.sol (3)
25-31: Noise seed separation correctly demonstrated in benchmark.The comment on line 26-27 appropriately warns that production noise must come from secret entropy. Using a distinct
noiseSeedfor the benchmark demonstrates the separation pattern without compromising the test's validity.
75-87: Helper function correctly generates 64-element planted secret.The block-based generation with
blocks = (N_WEAK + 15) / 16and bounds checking (if (idx >= N_WEAK) break) properly handles the expanded dimension.
89-124: B vector generation correctly implements puzzle construction.The implementation:
- Iterates over M_WEAK=96 rows
- Computes dot product using 4 blocks of 16 coefficients
- Adds error in range [-2, 2] via
int256(uint256(errorSeed) % 5) - 2- Stores result as big-endian u16
This mirrors the contract's verification logic, ensuring benchmark consistency.
scripts/BenchmarkTLOS.s.sol (4)
44-44: LWE noise parameter correctly documented.The log message reflects σ=25 Gaussian noise as specified in the PR objectives.
52-58: Noise seed separation correctly implemented.The warning comment (lines 52-54) and use of a distinct
noiseSeedproperly demonstrate the security requirement that production noise must come from true entropy, not public seeds. This aligns with the critical security note added to the contract.
107-119: Helper function correctly updated for 64-element secret.The return type
int8[64] memoryand dynamic block calculation are consistent with other files in this PR.
121-156: B vector generation correctly accepts noiseSeed parameter.The function signature update to include
bytes32 noiseSeedand its use in error seed derivation (line 144) properly implements noise separation. The block-based iteration matches the contract and other benchmark scripts.test/TLOSWithPuzzleV5.t.sol (6)
21-25: Test constants correctly mirror production parameters.The test suite uses the same hardened parameters as the production contract:
N_WEAK = 64,M_WEAK = 96PUZZLE_THRESHOLD_SQ = 400The comment on line 24 appropriately notes the calibration dependency.
37-37: State variable correctly updated to int8[64].The public
plantedSecretstorage variable matches the updated dimension.
85-91: Helper function signatures correctly accept 64-element arrays.Both
_commitHashand_powNonceForhave been updated to acceptint8[64] memory solution, maintaining consistency with the contract's puzzle solution type.Also applies to: 111-122
314-316: Loop bound correctly uses N_WEAK constant.Using
N_WEAKinstead of a hardcoded48ensures the loop adapts to the updated dimension and improves maintainability.
1027-1039: Test helper functions correctly implement updated parameters.Both
_generatePlantedSecretand_generateBVectoruse:
- Dynamic block calculation
(N_WEAK + 15) / 16- Correct bounds checking
- M_WEAK-sized output for bVector
These implementations are consistent with the benchmark scripts and contract verification logic.
Also applies to: 1041-1076
1064-1065: Note: Test helper derives noise from puzzle seed (acceptable for tests).Unlike the benchmark scripts which use a separate
noiseSeedto demonstrate production patterns, the test helper derives error from the puzzle seed. This is acceptable for testing since:
- Tests run in controlled environments without adversarial conditions
- The contract's security note and benchmark scripts correctly document the production requirement
No change needed, but ensure production deployments follow the noise separation pattern demonstrated in the benchmarks.
paper/tlos-paper.tex (5)
50-51: Abstract correctly summarizes updated security model.The abstract reflects the five-layer architecture with the hardened puzzle floor (2^101) and updated LWE parameters (n=384, σ=25).
81-88: Layer descriptions accurately reflect updated parameters.
- Layer 2: σ=25 with critical entropy note
- Layer 4: 3^64 ≈ 2^101 floor, 2.30M gas verification
- Layer 5: Hash-PoW correctly described as protocol-level throttle
921-941: Puzzle parameter table correctly updated.Table~\ref{tab:puzzle-params} accurately reflects:
- n=64, m=96, q=2039
- Ternary secret, error in [-2,2]
- τ=400 threshold
- 3^64 ≈ 2^101 search space
- 2.30M gas verification
These align with the contract constants and PR objectives.
617-629: LWE security table correctly reflects single production configuration.Table~\ref{tab:lwe-security} presents n=384, σ=25 with ~112-bit PQ security. The gas costs (4,734,943-18,184,574 for 64-640 gates) match the Tenderly measurements in the PR description.
1-50: Document comprehensively updated for hardened parameters.The paper consistently reflects the new security parameters throughout:
- σ=25 Gaussian noise for LWE layer
- n=64, m=96, threshold=400 for puzzle layer
- Updated gas costs and security estimates
- Five-layer model with Hash-PoW
No inconsistencies detected in the parameter updates.

🤖 Fix all issues with AI agents
In `@examples/TLOSTreasureHunt.sol`:
- Around line 139-141: The NatSpec for reveal is stale: it says "48-element
ternary array" but the function signature uses int8[64] puzzleSolution; update
the comment to match the current parameter size and allowed values (e.g.,
"64-element ternary array (-1, 0, or 1) solving the LWE puzzle") so the
documentation aligns with the reveal(bytes32 secret, int8[64] calldata
puzzleSolution) declaration.

296-299: Fix the outdated stddev value in the lattice estimator example.The example command shows
stddev=8.0, but the document consistently states σ=25 for the LWE layer (Lines 7, 14, 77, 130, 193, 247, 276). This inconsistency would cause users to estimate security for the wrong parameters.🔧 Proposed fix

371-374: Consider adding a 2^101 estimate for completeness.The security implications section estimates time for 2^20 to 2^40 guesses, but the new parameters provide 3^64 ≈ 2^101 security. Adding an estimate for the actual search space would better illustrate the infeasibility.

86-98: Puzzle parameters correctly updated to match WeakLWEPuzzleV7.The constants now align with the hardened Layer 4 parameters:
N_WEAK=64,M_WEAK=96,Q_WEAK=2039,PUZZLE_THRESHOLD_SQ=400. This addresses the previously flagged issue where example contracts lagged behind the main contract updates. Based on learnings, these values provide the expected 3^64 ≈ 2^101 search space.
26-28: Documentation correctly reflects the new security floor.The comment now accurately states the 3^64 ≈ 2^101 search space, consistent with the hardened parameters.
290-311: Claim function signature correctly updated for 64-element puzzle solution.The
puzzleSolutionparameter type changed fromint8[48]toint8[64], aligning withN_WEAK=64. The commit hash computation and puzzle verification logic remain sound.

int8[64], and the block calculation(N_WEAK + 15) / 16 = 4correctly covers all 64 indices. The bounds check at line 399 ensures safety whenN_WEAKisn't a multiple of 16.
419-497: _verifyPuzzle correctly implements hardened puzzle verification.Key verifications:
int8[64]solution andint16[64]planted arrays matchN_WEAK=64- Dynamic block loops
(N_WEAK + 15) / 16 = 4cover all 64 indices- 96 rows (
M_WEAK) with error range{-2,-1,0,1,2}(line 476:% 5 - 2)- Threshold 400 provides appropriate margin above expected norm (~192)
The modular arithmetic, residual centering, and norm accumulation logic are correctly preserved.
scripts/attacks/layer4-puzzle/lwe_puzzle_solver.py (2)
54-58: Parameters correctly updated to hardened V7 values.The constants align with the production Layer 4 puzzle requirements:
N_WEAK=64,M_WEAK=96,Q_WEAK=2039, andTHRESHOLD_SQ=400, providing the claimed 3^64 ≈ 2^101 search space. Based on learnings, these match the expected production parameters.
72-72: Domain separator correctly updated to v7.The
PUZZLE_DOMAINnow uses"TLOS-PlantedLWE-v7"which matches the contract's domain separator, ensuring off-chain generated puzzles will match on-chain verification.test/PuzzleVariants.t.sol (3)
18-25: Section comment and parameter assertions correctly aligned.The comment on line 18 now correctly reflects
n=64, m=96, q=2039, threshold=400, and the assertions at lines 21-24 verify these production parameters. The previous review comment about stale values has been addressed.
69-73: Security level assertion correctly updated to 2^101.The test now accurately reflects that V7 provides 3^64 ≈ 2^101.4 security bits, with the assertion
v7_bits >= 101. This aligns with the PR objectives and learnings.
77-87: Helper functions correctly updated for 64-element arrays.Both
_assertTernary64and_randomTernary64now iterate over 64 elements, matching theint8[64]array type used throughout the tests.examples/TLOSTreasureHunt.sol (4)
54-58: Constants correctly updated to V7 production parameters.The puzzle parameters
N_WEAK=64,M_WEAK=96,Q_WEAK=2039, andPUZZLE_THRESHOLD_SQ=400match the hardened Layer 4 puzzle requirements, providing 3^64 ≈ 2^101 search space security.
214-229: Dynamic block iteration correctly handles n=64.The
getPlantedSecretfunction usesblocks = (N_WEAK + 15) / 16to compute iteration count, making it resilient to parameter changes. Theint8[64] memoryreturn type correctly matches the new dimension.
248-324: Puzzle verification logic correctly adapted for n=64, m=96.The
_verifyPuzzlefunction:
- Uses
int8[64] calldataandint16[64] memoryfor correct sizing- Iterates
N_WEAK(64) for ternary validation and planted secret derivation- Iterates
M_WEAK(96) rows for residual computation- Uses dynamic
blockscalculation for inner loops- Compares against
PUZZLE_THRESHOLD_SQ(400)All hardcoded values have been replaced with constants or derived values, ensuring consistency with the updated parameters.
4-7: Educational example correctly documented.The contract header clearly indicates this is a teaching example and directs users to
TLOSWithPuzzleV5.solfor production use. This aligns with the coding guidelines for files in theexamples/directory.examples/TLOSSealedAuction.sol (5)
61-64: Constants correctly updated to hardened parameters.The puzzle parameters now match the required Layer 4 specifications: n=64, m=96, q=2039, threshold=400. This increases the brute-force search space from 3^48 ≈ 2^76 to 3^64 ≈ 2^101. Based on learnings, these are the correct production parameters for WeakLWEPuzzleV7.
21-21: Documentation accurately reflects hardened parameters.The security claims (3^64 ≈ 2^101) and gas estimate (2.30M) are consistent with the PR objectives and learnings.
Also applies to: 38-38
369-384: LGTM — Dynamic block calculation correctly handles 64-element array.The ceiling division
(N_WEAK + 15) / 16 = 4ensures all 64 elements are populated. The bounds check at line 378 safely guards against out-of-bounds access when N_WEAK isn't a multiple of 16.
408-484: LGTM — Puzzle verification correctly implements hardened parameters.The implementation properly:
- Validates all 64 solution elements are ternary
- Uses dynamic block calculation for both planted secret and matrix row iteration
- Generates errors in {-2, -1, 0, 1, 2} consistent with the threshold
- Centers residuals to [-Q/2, Q/2] for accurate norm computation
- Applies threshold 400 for valid solution acceptance
The logic matches the specification from learnings for WeakLWEPuzzleV7.
211-214: Public API correctly updated for 64-element puzzle solutions.The
revealBidfunction signature now acceptsint8[64]calldata, consistent with the hardened puzzle parameters throughout the contract.README.md (5)
7-7: LGTM! Parameters correctly updated throughout introductory sections.The LWE and puzzle parameters are consistently documented:
- LWE layer: σ=25, n=384, ~2^112 PQ security
- Puzzle layer: 3^64 ≈ 2^101 search space with 2.30M gas verification cost
Line 16 correctly shows "2.30M gas (Tenderly)" which addresses the past review comment about the gas figure inconsistency.
Based on learnings, these parameters match the production requirements.
Also applies to: 14-16, 26-26, 29-29
63-78: LGTM! Gas costs and optimizations section correctly updated.The gas costs table matches the learnings:
- 64 gates: 4,734,943 gas (7% of 60M block) ✓
- 640 gates: 18,184,574 gas (30% of 60M block) ✓
All parameter mentions are consistent:
- LWE: n=384, σ=25, ~2^112 PQ security
- Puzzle: n=64, m=96, q=2039, 2^101 floor
Based on learnings, these Tenderly benchmark results align with production measurements.
92-92: Consider re-benchmarking puzzlebdeployment cost for m=96.The comment notes that puzzle
bdeployment via SSTORE2 needs re-benchmarking for the new parameters (m increased from 72 to 96). Since thebvector size has grown by ~33%, the deployment cost may have increased proportionally.Is this re-benchmark task tracked in an issue, or should it be completed before merging?
Based on learnings, having accurate deployment costs is important for documentation completeness.
130-147: LGTM! Security properties section accurately documents the hardened parameters.The parameter table is complete and correct:
- All values match the learnings: n=64, m=96, q=2039, threshold=400, 3^64 ≈ 2^101, 2.30M gas
- The brute-force calculation at Line 145 is mathematically accurate: 3^64 ≈ 3.43×10^30 guesses at 10^9/sec ≈ 1.09×10^14 years
- Benchmark date (Jan 15, 2026) aligns with the PR creation date
Based on learnings, these are the correct production parameters for WeakLWEPuzzleV7.
188-188: LGTM! Parameter references throughout repository structure and testing sections are consistent.All scattered parameter mentions correctly reflect the hardened values:
- Puzzle: n=64, 2^101 (Lines 188, 218, 249, 269)
- LWE: n=384, σ=25, ~2^112 PQ (Lines 193, 247, 276)
The documentation maintains consistency across repository structure, example contracts, testing, and security disclaimers.
Also applies to: 193-193, 218-218, 247-249, 269-269, 276-277
✏️ Tip: You can disable this entire section by setting review_details to false in your review settings.
Addresses oracle review feedback that n=64 provides insufficient lattice security (brute-force 3^64 != actual security). Changes: - N_WEAK: 64 -> 128 - M_WEAK: 96 -> 192 - PUZZLE_THRESHOLD_SQ: 400 -> 800 - All puzzle solution arrays: int8[64] -> int8[128] Security: - Brute-force: 3^128 (lattice security requires estimator analysis) - Previous '2^101 security' claim removed - was brute-force, not lattice Gas (Tenderly, Jan 15 2026): - Puzzle verification: 8.62M (14% of 60M block) - Acceptable for one-time reveal operation All 157 tests pass.

In `@broadcast/BenchmarkPuzzleV8.s.sol/73571/run-1768480094184.json`:
- Around line 79-81: The metadata and AI summary disagree on intended puzzle
parameters: the PR title/learned recommendations list n=64, m=96, threshold=400
while the implementation and this artifact use n=128, m=192 and
PUZZLE_THRESHOLD_SQ=800; decide which parameter set is authoritative, update the
implementation or artifact to match the chosen set, and align the PR
title/description and commit messages accordingly (if keeping
n=64/m=96/threshold=400, revert any changes that set n=128/m=192 and
PUZZLE_THRESHOLD_SQ=800; if adopting the larger parameters, update the PR title,
description, and any documentation to state n=128, m=192,
PUZZLE_THRESHOLD_SQ=800 and note the gas/security tradeoffs).
In `@broadcast/BenchmarkTLOS.s.sol/73571/run-1768462759687.json`:
- Around line 45-56: Update the constants in TLOSWithPuzzleV5.sol so the source
matches the deployed artifact: set N_WEAK to 64, M_WEAK to 96, and
PUZZLE_THRESHOLD_SQ to 400 (also verify any related constant for q equals 2039
and update if present); change the values where N_WEAK, M_WEAK, and
PUZZLE_THRESHOLD_SQ are defined to these new literals and run a
build/verification to ensure bytecode and constructor arguments align with the
deployed BenchmarkTLOS.s.sol artifact.
In `@contracts/WeakLWEPuzzleV7.sol`:
- Around line 4-15: The constants and header in WeakLWEPuzzleV7 (N_WEAK, M_WEAK,
THRESHOLD_SQ and the header/search-space comment) are set to a doubled testing
variant (128/192/800) but must match the production learning objectives
(64/96/400); change N_WEAK to 64, M_WEAK to 96, THRESHOLD_SQ to 400 and update
the top-of-contract comments (title/notice/@dev/search-space) to reflect n=64,
m=96, threshold=400 and 3^64 search space, or if you intentionally keep the 128
variant then explicitly state this is a testing-only hardened variant in the
header and update project documentation and gas-cost notes to reflect the
divergence—make the edit around the constant declarations and the contract
header text in WeakLWEPuzzleV7.
In `@examples/TLOSRecovery.sol`:
- Line 11: The constants in TLOSRecovery.sol currently implement a
higher-parameter puzzle (N_WEAK, M_WEAK, PUZZLE_THRESHOLD_SQ) that yields 3^128,
but the PR and learnings require n=64, m=96, threshold=400; update the constant
definitions N_WEAK -> 64, M_WEAK -> 96, and PUZZLE_THRESHOLD_SQ -> 400 (and any
other occurrences of these symbols on lines ~22-25) so the implemented
parameters match the stated PR objectives, and ensure any derived computations
or comments that reference the prior values are adjusted accordingly.
In `@examples/TLOSSealedAuction.sol`:
- Line 38: The inline comment stating "verify puzzle (2.30M gas)" is stale for
the current parameters (n=128, m=192); update that comment to reflect the new
estimated gas cost (e.g., "~8.62M gas" or the precise measured value) so it
matches the implemented n=128 configuration in examples/TLOSSealedAuction.sol;
replace the old gas number in the comment text with the updated estimate.
- Line 170: The inline comment uses the wrong array size; update the comment to
match the solvePlantedLWE signature by changing int8[64] to int8[128] so the
example declaration (puzzleSolution = solvePlantedLWE(bidSeed)) reflects the
actual return type of solvePlantedLWE; locate the comment referencing
puzzleSolution and bidSeed and adjust the array type to int8[128].
- Around line 61-64: The constants N_WEAK, M_WEAK, and PUZZLE_THRESHOLD_SQ in
the contract are inconsistent with the PR intent (should be n=64, m=96,
threshold=400); update the values by changing N_WEAK to 64, M_WEAK to 96 and
PUZZLE_THRESHOLD_SQ to 400 (leave Q_WEAK unless other docs require adjustment),
and ensure any comments or tests referencing n=128/m=192/800 are updated to
match the new parameters so code, PR description, and learnings remain
consistent.
In `@out/TLOSRecovery.sol/TLOSRecovery.json`:
- Line 1: The contract uses incorrect puzzle parameters: update the constants
N_WEAK (change 128 to 64), M_WEAK (change 192 to 96), and PUZZLE_THRESHOLD_SQ
(change 800 to 400) to match the production spec; also set Q_WEAK to the
production modulus (2039) if it’s defined, and update the contract notice/doc
comments (devdoc/userdoc) to reflect these production values or explicitly state
why larger demo parameters were chosen.
In `@README.md`:
- Line 92: The phrase "re-benchmark for n=64" is stale; update or remove that
reference so it matches the README's documented parameters (n=128) — locate the
exact string "re-benchmark for n=64" and either change it to "re-benchmark for
n=128" or remove the parenthetical entirely to avoid confusion.
In `@target/debug/deps/tlos-2c634a972e903fd5.d`:
- Around line 1-11: This tracked compiler artifact tlos-2c634a972e903fd5.d
should be removed from version control; run git rm --cached on
target/debug/deps/tlos-2c634a972e903fd5.d (or git rm --cached -r target/ to
untrack all target files), commit the change, and push; ensure target/ is
present in .gitignore so the file and other build artifacts remain untracked
going forward.
In `@target/debug/deps/tlos-cfdaea6b7ce3a170.d`:
- Around line 1-13: The PR accidentally committed Cargo build artifacts; remove
them from version control and re-apply .gitignore by running: git rm -r --cached
target/; ensure your .gitignore contains the Cargo target directory entry (it
already does), then commit the removal with a clear message (e.g., "remove
tracked build artifacts from target/") and push; verify no files under the Cargo
target directory remain tracked and CI no longer shows these files.
In `@test/TLOSWithPuzzleV5.t.sol`:
- Around line 21-25: The test constants N_WEAK, M_WEAK, and PUZZLE_THRESHOLD_SQ
are inconsistent with the PR objective; update the values in
TLOSWithPuzzleV5.t.sol by setting N_WEAK = 64, M_WEAK = 96 and
PUZZLE_THRESHOLD_SQ = 400 (and update the calibration comment that currently
references n=128,m=192 to reflect n=64,m=96 and threshold=400) so the test
parameters match the intended production parameters.

commit(bytes32): Now documents the puzzle-enabled hash format (keccak256(abi.encode(msg.sender, input, puzzleSolution))).reveal(bytes32): Notes that puzzle-enabled contracts should userevealWithPuzzle()instead.The ABI and method identifiers are unchanged, preserving interface compatibility. These documentation updates appropriately reflect the puzzle layer enhancements described in the PR objectives.

In @.gitignore:
- Around line 9-13: Remove the duplicated ignore entries: delete the repeated
lines for "target/", "out/", "cache/", and "paper/*.aux" so each of those
patterns appears only once in the .gitignore, leaving the unique "broadcast/"
entry intact; ensure you consolidate duplicates rather than adding new lines so
the file lists each ignore pattern exactly once.

7-7: LGTM: Overview and security layer documentation accurately reflects hardened parameters.The security claims are correctly stated:
- LWE layer (n=384, σ=25) maintains ~2^112 PQ security.
- Puzzle layer (n=128, m=192) provides 3^128 brute-force floor with lattice security appropriately marked as TBD.
- Gas cost of 8.62M (14% of 60M block) is documented consistently.
Based on learnings, this PR intentionally exceeds the original n=64, m=96 proposal to further harden against attacks.
Also applies to: 14-14, 16-16, 26-26, 29-29
63-63: LGTM: Gas costs and storage calculations are correct and internally consistent.Verified:
- Puzzle
bsize: 192 samples × 2 bytes (u16) = 384 bytes ✓- Gas range 4.7M–18.2M matches the table entries ✓
- Line 63 clarification distinguishes total gas from puzzle-only verification ✓
Past review comment about stale "n=64" reference is resolved.
Also applies to: 67-70, 77-78, 92-92, 98-98
112-112: LGTM: Security properties and parameter table are accurate and consistent.Verified:
- Puzzle parameters table correctly documents n=128, m=192, threshold=800, 3^128 search space ✓
- LWE layer (n=384, σ=25) security claim (~2^112 PQ) aligns with retrieved learnings ✓
- Line 112 appropriately notes the puzzle is a one-time floor, not per-guess protection ✓
- Lattice security marked as TBD pending estimator analysis ✓
Also applies to: 130-130, 136-143, 145-145
186-186: LGTM: Repository structure and examples documentation is consistent with parameter updates.All references to puzzle (n=128, 3^128) and LWE layer (σ=25) parameters are correct and align with the rest of the README.
Also applies to: 191-191, 216-216, 245-245, 247-247
267-267: LGTM: Testing and security disclaimer sections are accurate and appropriately cautious.Security claims are consistent:
- Test coverage documents n=128, 3^128 puzzle testing ✓
- LWE layer ~2^112 PQ security (n=384, σ=25) ✓
- Puzzle lattice security appropriately marked as TBD ✓
- Disclaimer encourages independent cryptanalysis ✓
Also applies to: 274-276

✅ PR title corrected to reflect the actual implementation parameters (n=128, m=192, threshold=800) The changes align with the actual codebase state where the production Layer 4 puzzle uses n=128, m=192 parameters (not the n=64, m=96 initially mentioned). The gas benchmarks and test assertions are now consistent with the higher-parameter configuration. I'll resolve the review comments. 🧠 Learnings used✅ Actions performedComments resolved. |
