Secure certificate-based aggregate signature scheme
Chen Jiannen · Computer Engineering and Applications Journal · 2013
Certificate-based public key cryptography overcomes the certificate management problem in traditional public key system and the key escrow problem in the identity-based public key cryptography. An aggregate signature scheme can aggregate signatures on distinct messages from distinct users into a single signature. Based on bilinear pairings and the hardness of Computational Diffie-Hellman problem, a secure certificate-based aggregate signature scheme is proposed and its security is proven in the random oracle model.
