摘　　要：将指定验证者的签名引入到门限代理签名方案中,综合了两种方案的优点,基于离散对数,构造了一个已知签名者的指定验证者门限代理签名方案.该方案可以有效地限制代理终止时间与代理消息的范围,指定验证者可以确定代理签名群中实际签名者的身份,验证签名时,无须传送验证参数,节省了通信成本.Based on discrete logarithms, a designated-verifier threshold proxy signature scheme with known signers is proposed. It integrates the advantages of designated-verifier signature scheme and threshold proxy signature scheme. Moreover, in this scheme, the proxy signature time and the proxy message can be controlled, and the designated-verifier can ascertain the identities of the group signers who made the proxy signature. It is not necessary to send the parameter in the signature verification phase, which saves the cost of communication.
