On security of a Certificateless Aggregate Signature Scheme

Limin Shen and Yinxia Sun

Abstract

Aggregate signatures are useful in special areas where the signatures on many different messages generated by many different users need to be compressed. Recently, Xiong et al. proposed a certificateless aggregate signature scheme provably secure in the random oracle model under the Computational Diffie-Hellman assumption. Unfortunately, by giving concrete attacks, we indicate that Xiong et al. aggregate signature scheme does not meet the basic requirement of unforgeability.
