Title:
A Cryptanalysis of NOVA Signature Scheme
Authors: Dongyu Wu
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.
