摘要
给出一种可收回代理权的代理签名方案,它具有一些代理签名方案的新特点:可回收性和可追查性。这个方案具有在原始签名者需要时,收回某个代理签名者代理权的特性。另外,当出现争议时,验证者可通过代理群管理员追查出代理签名者的身份,因此可以间接起到对代理签名者的监督,有效防止代理签名者签名权利的滥用。
A proxy signature scheme recalling the proxy signature right is presented. The scheme had the properties of recalling the proxy right and traceability. The proposed scheme could recall the proxy signature right of the proxy signer delegated by the original signer if the original signer needed. Furthermore, the verifier could reveal the real identity of the proxy signer with the help of the GP in appearing of disputation. Therefore the scheme can indirectly supervise these proxy signers and effectively prevent these proxy signers from misusing their proxy signature rights.
