supercop-blockciphers

This repository contains fast block cipher implementations (for x86-64) in counter-mode for the SUPERCOP cryptographic benchmarking framework. These are the artifacts of the implementation/integration part of my Master's Thesis "Block Ciphers: Fast Implementations on x86-64 Architecture". Fulltext is available at: http://urn.fi/URN:NBN:fi:oulu-201305311409

SUPERCOP: http://bench.cr.yp.to/supercop.html

Installation: Copy contents of crypto_stream/ of this repository to crypto_stream/ in SUPERCOP package.

Licensing note: Some implementations contain GPLv2 licensed code, while other are mix of permissive licenses (ISC, new BSD, MIT, public-domain).

beyond_master branch

This branch contains new implementations, that were not included in Master's Thesis.

New implementations so far:

  • Camellia AES-NI/AVX2
  • Serpent AVX2 (by Johannes Götzfried)
  • Twofish AVX2 (using vpgatherdd)
  • Twofish AVX2 (without vpgatherdd, based on AVX impl.)
  • Blowfish AVX2 (using vpgatherdd)

Results on Intel Core i5-4570 (haswell, cpuid: 306C3h):

  • Blowfish

    • 8-way AVX bit-sliced: 6.16 cycles/byte
    • 8-way SSSE3 bit-sliced (Käsper & Schwabe): 6.36 cycles/byte
    • 2-way table look-up: 7.85 cycles/byte
    • 1-way table look-up: 10.87 cycles/byte
  • Camellia

    • 2-way table look-up: 10.37 cycles/byte
    • 1-way table look-up: 16.72 cycles/byte
    • OpenSSL: 18.91 cycles/byte
