在普通数字签名中，密钥泄露使得用这个密钥产生的数字签名变得无效，具有前向安全特性的数字签名体制解决了密钥泄露问题的困惑。聚合签名的本质是把 n 个来自不同消息的签名聚合成一个短签名。前向安全聚合签名则兼容了两者的优点，本文指出了文[7]的方案不具备前向安全性，并基于双线性对提出了一个新的前向安全聚合签名方案，最后对所提方案的正确性和安全性做了简单的分析。“,”Ordinary digital signatures have an inherent weakness:if the secret key is leaked, then all signatures, even the ones generated before the leak, are no longer trustworthy. Forward secure scheme has been suggested for solving this problem. An aggregate signature is a signature that aggregate n distinct signatures into a single short signature. A forward secure aggregate signature scheme combines with the two mentioned advantages. This paper points out that the scheme in [7] is not forward secure, and proposes a new forward secure aggregate signature scheme from bilinear maps . Finally,this paper analyzes the correctness and security of the scheme.
