摘要/Abstract

摘要： 提出了一种新的代理盲签名方案,在此基础上,考虑了签名方程中所有可能的参数选取方法并由此给出了构造代理盲签名方案的一般方法,在ElGamal型签名方案的基础上给出了相应的6种代理盲签名方案.从计算时间复杂性的角度对这些方案的性能进行了比较.这些签名方案具有不可伪造性、可区分性、不可抵赖性和可注销性等性质.

Abstract: A new proxy blind signature scheme is proposed.Based on this, all possible parameters to be chosen in signature equations are considered and a general method to construct proxy blind signature based on ElGamal's signature is obtained.From the view of computational complexity, the comparisons between these schemes show which one is better than others.The security of these schemes is also discussed and shown that they have good properties as unforgeability, distinguish-ability, non-repudiation and revocability etc.

Key words: digital signature, blind signature, proxy blind signature, proxy signature
