Abstract:

For the problems existed in computational efficiency, communication cost and security in the current synchronized aggregate signature schemes, a clock synchronized aggregate signature scheme based on Camenisch Lysyanskayasignature was proposed, which proved to be secure under LRSW as sumptions. Further, compared with existed schemes, the new scheme has the excellent features with a short length of the public key and that of the signature, and it improves the computational efficiency of the signature algorithm.

Key words: aggregate signature, clock synchronization, provably secure, bilinear pairing
