摘要 针对Wu等人提出的基于身份的代理签名方案进行分析,指出该方案不满足公开验证性和不可伪造性,提出一种改进的基于身份的代理签名方案。该方案基于双线性对运算和离散对数的困难性问题,满足代理签名的一般性安全要求。经过分析证明,并与现有的其他方案比较,该方案效率较高。 We analysed the ID-based proxy signature scheme presented by Wu et al.,and pointed out that it doesn＇t satisfy the public verifiability and un-forgeability. Therefore we proposed an improved ID-based proxy signature scheme. This one is based on bilinear pairings computation and difficulty of discrete logarithm problem,it satisfies the general safety requirements of proxy signature. It is proved by analysis and comparing with existing schemes that our scheme has higher efficiency.
