摘要
已有的指定验证人代理签名方案一般都不具有前向安全的性质.基于一种具有前向安全性质的指定验证人代理签名方案,提出了具有新特点的代理签名方案.给出的指定验证人代理签名方案不仅满足前向安全的性质,还满足匿名性和可跟踪性.
Generally the existing designated-verifier proxy signature can not provide forward-security. Based on a forward secure designated-verifier proxy signature scheme, proposed a proxy signature with new properties. So the designated-verifier proxy signature scheme presented is not only forward secure but also anonymous and traceable.
