Abstract: A new secure and efficient proxy blind signature scheme based on bilinear pairings is proposed, and it is compared with those proposed schemes. The new scheme overcomes the security leaks and has the merits of little communication and low computation complexity etc.

Key words: Proxy blind signature, Bilinear pairings, Blindness, Unlinkability

摘要： 提出了一种基于双线性对的新型安全有效代理盲签名方案，并与已提出的代理盲签名方案进行了比较分析。新方案克服了已提出方案的安全隐患，并且具有通信量小、计算复杂性低等优点。
