摘要
为了克服基于身份的数字签名所固有的问题,同时解决签名在一些特殊环境中产生的效率问题,利用双线性对的技术,结合自认证签名和聚合签名的概念,提出了一个自认证聚合签名方案,该方案合并了自认证签名和聚合签名的优势。最后在随机预言模型下给出了方案的安全性证明。
To overcome the inherent problems in the identity-based digital signature,and solve the efficiency problem in some special environment,here,a self-certified aggregate signature scheme from pairings on elliptic curves was proposed,by using the concepts of aggregate signatures and self-certified signatures.The scheme incorporates the advantages of self-certified signatures and aggregate signatures.In the end,a security proof in random oracle model was prorided.
