Cryptanalysis of the SNOVA signature scheme

Authors: Peigen Li, Jintai Ding


SNOVA is a variant of a UOV-type signature scheme over a noncommutative ring. In this article, we demonstrate that certain
parameters provided by authors in SNOVA fail to meet the NIST security level, and the complexities are lower than those claimed by SNOVA.
