Abstract: By utilizing the advantage of aggregate signature, this paper proposes an anonymous proxy blind aggregate signature scheme based on bilinear pairing. An aggregate signature scheme aggregates n signatures into one, thus n verification equations can be reduced to become one. Theory analysis proves that the scheme provides privacy protection for the proxy signer and blinds the message, and in case of dispute later on, the identity of the proxy signer can be traced.

摘要： 利用聚合签名的优点，提出一种基于双线性对的匿代理盲聚合签名方案。聚合签名能将 个签名聚合成唯一的一个短签名，从而使 个验证等式减少为一个验证等式。理论分析证明，该方案保护了代理签名人的隐私权，使签名的消息不可见，在事后引起争议时还可以追踪到代理签名人的身份。
