【摘要】 Hsu提出一个新的已知签名者的不可否认的门限代理签名方案.在该方案中,真正的代理签名者的身份是已知的.但是,在某些时候,我们不仅需要知道代理签名者的身份,而且需要知道真正验证者的身份.总而言之,我们需要知道代理签名方案中的所有参与者的身份.本文所提方案可以证实真正代理签名者和验证者的身份.
【Abstract】 Hsu proposed a new nonrepudiable threshold proxy signature scheme with known sig ners[1].In his scheme, the identifies of the actual proxy signers of the proxy signature can be known. But in some case, we not only want to know who th e actual proxy signers are, but also want to know who the actual verifiers are. In a word, we want to know both sides of the participants in a proxy signature. In this paper, the proposed scheme can provides the capability to identify the a ctual proxy signers and the actual proxy verifiers.
【Key words】 digital signature; proxy signature; threshold proxy signature; nonrepudiation;
