针对目前同步聚合签名方案在计算效率、通信成本和安全性等方面存在的问题，提出一种基于 Camenisch Lysyanskaya-签名的时钟同步聚合签名方案，并在 LRSW 假设下，证明了该方案的安全性。结果表明，与已有方案相比，新方案减小了签名的通信成本和计算量，并具有较短的公钥长度和聚合签名长度。

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 assumptions.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.
