Falcon is a Post Quantum Digital Signature Scheme that has been standardized by NIST. This repository is based on the Round 3 submission of Falcon. New functions have been added to work with the Doge Protocol Blockchain.

Two new functions, crypto_sign_signature_with_key and crypto_sign_verify functions
have been added in the reference implementation for falcon512.
In subsequent iterations, these changes will be removed in favor of maintaining
all changes outside of the core cryptography libraries.
These changes have been primarily added for generating WebAssemblies for use in Browser Extensions.
Each implementation under Reference_Implementation and
Optimized_Implementation has its own Makefile; when used, it compiles
the code along with the test vector generator in KAT/generator/. The
resulting binary (created in a subdirectory called build), when
executed, produced the .req and .rsp files, which should be identical
to the ones provided in KAT/.
The *cxm4 implementations are for the ARM Cortex M4, a CPU normally
found in microcontrollers. Cross-compilation is normally used for such
implementations. The Makefiles invoke the compiler under the name
arm-linux-gcc and expect that compiler to come with a minimal but
functional libc; moreover, the use of inline assembly follows the syntax
extensions supported by GCC and Clang. The Buildroot project can be used to obtain an appropriate
cross-compilation toolchain. The resulting binary can be executed under
emulation with QEMU.
All other implementations assume a native C compiler which is invoked with the command name 'c99' and flags '-W -Wall -O2'.
The implementation in Extra/c/ has its own Makefile; it compiles into
two command-line tools, test_falcon and speed. test_falcon runs
some self-tests. speed runs some benchmarks.
