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.
