Abstract: An improved multi-signature with proxy signers based on Guillou-Quisquater signature is proposed.It is a multi-signature with special property that proxy signers instead of some signers produce a multi-signature with the other signers.It can distinguish the identities of the signature’s participators.The security analysis of the scheme shows that the signature can not be forged.

摘要： 提出了一种改进的基于G-Q签名体制的有代理的多重签名方案。它允许部分原始签名人分别委托代理人与其他原始签名人共同生成有效签名。方案可以有效地区分签名参与者的身份，以便发生争议时能明确责任。对方案的签名算法进行了安全性分析，说明了方案的正确性和不可伪造性。
