Cryptanalysis of the SNOVA signature scheme
Abstract
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.
