Abstract: In this paper,a shared verification proxy signature scheme with message recovery is proposed.In the scheme,n verifiers share the verification power of signature,so that only t or more verifiers of the specified group together can recover the message from signature and verify the validity of proxy signature.It has the properties of proxy signature scheme and the signing message is unnecessary to be transmitted.Compared with other proxy signature schemes,the scheme can reduce the communication cost and the risk of verifier deception.In the case of deception,the scheme can decide exactly which verifier deceives.

Key words: message-recovery, shared verification, proxy signature

摘要: 提出了一个具有消息恢复的共享验证代理签名方案。在该方案中,把签名的验证权让[n]个验证人分享,使得指定验证组中的[t]个或更多验证人合作能从签名中恢复消息并能验证签名的有效性。该方案满足代理签名方案的安全要求,传送签名时无需传送消息,和其他代理签名方案相比,降低了通信开销;同时也降低了验证人欺骗的风险,万一遇到验证人欺骗,该方案能准确地检查出哪一个验证人在欺骗。
