具有消息恢复的指定验证者的代理盲签名

摘要

设计了一种新的具备消息恢复特性的指定验证者的代理盲签名方案.方案的安全性建立在椭圆曲线离散对数难解性之上,并对其进行了安全性分析.方案在验证签名过程中,消息可恢复出来.另外,方案节省了信息的传输量,有效地降低成本,有广泛的应用价值.%In this paper, we design a new proxy blind signature scheme of designated verifier with message recovery property and its security is based on elliptic curve discrete logarithm problem (ECDLP). We also analyze the security of the new scheme. During the process of verifying signature, message can be recovered. Moreover, this scheme reduces the amount of information transmission, lowers the cost efficiently and has more extensive application value
