A Cryptanalysis of NOVA Signature Scheme

Dongyu Wu, Beijing Institute of Mathematical Sciences and Applications
Abstract

NOVA signature scheme is a UOV-type signature scheme over a non-commutative coefficient ring with a novel structural map. In this article we show that a randomly generated central map for the scheme is very likely insecure and may suffer from a forgery attack in polynomial time.
