Paper 2021/938

Plactic signatures (insecure?)

Daniel R. L. Brown, BlackBerry
Abstract

Plactic signatures use the plactic monoid (semistandard tableaus with Knuth’s associative multiplication) and full-domain hashing (SHAKE). Monico found an attack which likely makes plactic signatures insecure.

Note: This version title and abstract are change to notify readers that C. Monico found an attack that likely breaks (all possible versions) plactic signatures.
