摘要
文章在研究有代理的多重数字签名的基础上,将前向安全的概念引入在有代理多重数字签名中,提出了一个具有前向安全性的有代理多重数字签名方案,在这种多重签名中,允许部分签名人委托其代理人进行签名.同时该方案能实现即使所有签名人的签名密钥被泄露,攻击者也无法伪造前阶段签名,以前所产生的有代理多重数字签名依然有效.
Based on the study of multi-signature scheme with proxy signers, the paper proposes a forward secure multisignature scheme by combining the concept of forward security with multi-signature. In the scheme, some signers can delegate their deputy to proxy signers. The scheme can be realized even if all the signatures keys of signers are leaked, the attacker can not forged the signature of the previous stage previous generated proxy multi-signature remain valid.
