Raccoon Signature Scheme -- Reference Code

nist-ref

Copyright (c) 2023 Raccoon Signature Team. See LICENSE.

For information about NIST PQC Signature submission requirements, see the call for proposals and submission file documentation.

Root level directory structure of this repository:

• ref-c: Written in the style of a "portable ANSI C reference implementation" for NIST, and supports NIST API and KAT generation. This code has options for 32-bit CRT NTT arithmetic (default: off) and LFSR vs ASCON masking random (default: lfsr), used for various discussions.
• ref-py: Python implementation, also with NIST KAT testbench.
• doc: Documentation, including doc/raccoon.pdf, the current specification.

Currently we are not delivering an AVX2, Cortex M4, or FPGA code to NIST; those aspects will be just discussed in the delivered document.

Generating KATs

• The C implementation generates the KATs with ./genkats.sh.
• With the C implementation can also obtain benchmarks with ./bench.sh. The standard ./xtest test binary generated by make is also useful.
• The Python implementation takes a some minutes with python3 test_genkat.py since each KAT file contains a set of 100 test vectors (can be modified).

Running sha256sum *.rsp in the C implementation currently gives the following hashes for 100-vector response files generated by both implementations (albeit with Python one can may want to opt for 10 test vectors). See the directory ref-data rsp hashes for 10 vectors, preliminary benchmarks, and additional data.
