Cryptanalysis of a certificateless aggregate signature scheme [PDF]
2016 International Conference on Computing, Communication and Automation (ICCCA), 2016 Certificateless aggregate signature allows mapping n signatures on n distinct messages from n distinct users into a single length signature. Recently Deng et al proposed CLAS Scheme which is an improvement of Hou et al scheme and claims that their scheme is secure against type II adversary but unfortunately it is found unsecure by applying the Honest ...

Insecurity of a certificateless aggregate signature scheme [PDF]
Security and Communication Networks, 2016 AbstractAs an important kind of digital signature, the aggregate signature could aggregate n signatures into a signature and verify those signatures simultaneously. It is suitable for the constrained environment with limited ability of computation and communication. Recently, Chen et al.
