Plactic signatures
Daniel R. L. Brown
Abstract
Plactic signatures use the plactic monoid (semistandard tableaus with Knuth’s associative multiplication) and full-domain hashing (SHAKE).
Note: This version adds some adds some preliminary timing results (with some code to generate the timings). Only two of the previous three plactic multiplications implementation are kept, with none marked as optimized. The attempted constant-time implementation is reported to fail the TIMECOP tests (as would be expected from its variable array-indexing).
