摘要
构造了一个新的t次代理签名方案,该方案运用秘密分割的思想,实现了一次授权可以使用t次的新特性。与传统的授权代理签名方案相比,该方案减少了时间开销,降低了通信量,并且能够有效地限制代理签名者的签名次数。
Based on the concept of secret sharing, a new t-times proxy signature scheme is proposed. The scheme can provide a new charac- teristic that one warrant can be used for t-times. Compared with the traditional one-time proxy signature, this scheme can effectively restrict the times of signature that the proxy signer can make.
