摘要:

基于双线性对及3个困难性问题(IFP、DLP、CDHP)提出了新的多重数字签名方案。新方案将广播多重数字签名中签名快速的优点应用到按序多重数字签名,改变签名的一般机制,使签名者同时进行签名;然后,由可信任第三方验证签名,验证通过后发送给验证者;最后,由验证者将签名转变为按序的。同时,分析了方案在3个困难问题、防伪攻击和抗部分成员合谋攻击方面的安全性能。新方案具有计算量少、算法简单、获取签名速度快、安全性强等优点。

Abstract:

Based on bilinear pairing and three complicated problems,a new digital multi-signature scheme was pro-posed.In the new scheme,the advantage of fast signature in broadcasting digital multi-signature was applied to se-quential digital multi-signature.By changing the general mechanism of signature,signing could be done simultane-ously by the signers.Then,the signature was sent to verifier after it was verified by trusted third party.The trans-formation from concurrent signature to sequential signature was finally realized by the verifier.The security capa-bilities in three complicated problems,anti-fake attack and anti-conspiracy attack from some members of the new scheme were analyzed.Proposed scheme has many advantages over the old ones,such as fewer calculation,simpler algorithm,faster signing,higher security.

Key words: digital multi-signature, sequential signature, broadcasting signature, security
