摘　　要：将前向安全特性和盲签名基本思想融为一体,设计了一种基于ElGamal体制的前向安全强盲签名方案,方案的安全性基于有限域上离散对数难解性假设。通过详细的安全性分析表明,新方案具有前向安全性、强盲性、抗伪造性等性质,有一定的理论和实用价值。This paper combines the fundamental ideas of tbrward security and blind signature to design a forwardsecure strong blind signature scheme based on ElGamal. The security of the proposed scheme is based on the assumption of difficulty in solving the discrete logarithm problem in the finite field. With the detailed analysis of security, the proposed scheme not only has the features of forward-secure, strong blindness and resisting forging attack, but also has certain theoretical and practical values.
