Cryptanalysis of the SNOVA signature scheme

ePrint Report: Cryptanalysis of the SNOVA signature scheme

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.
