An Attack on a Certificateless Signature Scheme

Xuefei Cao, Kenneth G. Paterson, and Weidong Kou

Abstract

This paper demonstrates that a certificateless signature scheme recently proposed by Gorantla and Saxena is insecure. It is shown that an adversary who replaces the public key of a signer can then forge valid signatures for that signer without knowledge of the signer's private key.
