摘　　要：设计了一种高效的证书聚合短签名方案,与现有同类签名方案相比,新的证书聚合签名方案具有:签名长度短,效率高,而且签名长度及在验证算法中涉及的双线性对运算的个数都与参与聚合签名的人数无关.最后,证明了所提出的签名方案在随机预言机模型下是基于CDH困难性问题.An efficient certificate-based aggregate short signature scheme is proposed.Compared with such kinds of signature schemes available recently,the new proposed certificate-based aggregate signature scheme has some attractive features.It has the shortest aggregate signature length and the highest efficiency among the available certificate-based aggregate signature schemes.Moreover,the length of the aggregate signature and the number of bilinear pairings needed in the aggregate signature verification are independent from the number of signer take part in the signature scheme.Finally,the security of the proposed signature scheme can be reduced to the CDH problem under the random oracle model.
