Meteor-NC v1.0.0: Initial Release

Meteor-NC v1.0.0: Initial Release

A quantum-resistant public-key cryptosystem achieving 817K msg/s encryption.

Highlights

✅ Quantum-Resistant: Proven secure against Shor's algorithm
✅ High Performance: 817K encryptions/s, 689K decryptions/s (NVIDIA A100)
✅ Multiple Implementations: CPU, GPU (standard), GPU (optimized 5×)
✅ Comprehensive Validation: Security verification tools included

What's Included

• meteor_nc_cpu.py - CPU implementation
• meteor_nc_gpu.py - GPU standard implementation
• meteor_nc_gpu2.py - GPU optimized implementation (5.4× faster)
• meteor_nc_validation.py - Security validation suite
• examples/benchmark_comparison.py - Performance comparison

Performance Benchmarks

Implementation	Encryption	Decryption	Throughput
CPU	0.6ms	270ms	-
GPU (Standard)	6.1ms	39ms	128K msg/s
GPU (Optimized)	6.1ms	7.3ms	689K msg/s

Security Analysis

• Non-commutativity: ||[πᵢ,πⱼ]|| = 63.0 ✅
• No periodic structure ✅
• Grover complexity: 2^1,015,806 ✅

Installation

For GPU: pip install cupy-cuda12x

## Quick Start
```pythonfrom meteor_nc_gpu2 import MeteorNC_GPUcrypto = MeteorNC_GPU(n=256, m=10)
crypto.key_gen()ciphertexts = crypto.encrypt_batch(messages)
plaintexts, _ = crypto.decrypt_batch(ciphertexts)
