改进的签名长度固定的无证书聚合签名方案
Improved certificateless aggregate signature with constant length
摘要
Abstract
The existing certificateless aggregate signature schemes with constant length have either known security flaws or large communication overheads.This paper presented an improved certificateless aggregate signature scheme.It substituted a random integer for state information,and broadcasted to all signers.The new scheme is provably secure in the random oracle model under the computational Diffie-Hellman assumption against a polynomial time adversary.The comparative analysis indi-cates that the improved scheme has lower communication loads,and requires only 1 broadcast in status information negotiation phase.With the new scheme,it is easier to construct many-to-one authentication schemes in a resource-constrained network en-vironment.关键词
