Abstract: A new proxy multi-signature scheme with message recovery is proposed based on discrete logarithms.In this scheme,every verifier can recover the message and verify the signature,so the scheme can reduce the communication costs;The verifier can verify the signature one time or twice by the actual situation,so it can realize a kind of scheme with the dual security of protection.

Key words: proxy signature, message recovery, multi-signature, discrete logarithms

摘要: 基于离散对数提出了一个具有消息恢复的代理多重签名方案。任何验证者都可以恢复消息并验证签名,因此减少了传输信息本身所需要的成本;验证者可根据实际情况,实施一次或两次验证,从而实现了双重安全保护机制。
