malb committed a2a70d533ae6 to M4RI renamed mzd_apply_p_right_tri to mzd_apply_p_right_trans_tri because this is what it does some some sparse-ish performance enhancements

malb / algebraic_attacks (created 14 months ago) This repository mainly holds code snippets for experimentation with algebraic attacks (and some general crypto code). The quality of this code is not 'release ready' at all. Although the code should work in general there is a lot of scratch, wrong and pathetic code in this repository. Also, some of this code dates back to my Diplomarbeit (master's thesis) and should be considered broken and outdated. By default all code listed here is released under the GPLv2+. Don't hesitate to ping me if you need something under some more permissive license like BSD-style. |
malb / M4RI (created 15 months ago)M4RI is a library for fast arithmetic with dense matrices over F2. It was started by Gregory Bard, is maintained by Martin Albrecht. Several people contributed to it. The name M4RI comes from the first implemented algorithm: The "Method of the Four Russians" inversion algorithm published by Gregory Bard. This algorithm in turn is named after the "Method of the Four Russians" multiplication algorithm which is probably better referred to as Kronrod's method. M4RI is used by the Sage mathematics software and the PolyBoRi library. M4RI is available under the General Public License Version 2 or later (GPLv2+). |
