摘要
给出一种可容忍信息泄露的指定验证者盲代理签名方案,它具有一些代理签名方案的新特点:匿名性和可追踪性。指定验证者在验证代理签名之后只能确信代理签名是代表原始签名者的签名而无法确定代理签名者身份;当出现争议时,指定验证者可通过代理群管理员追查出代理签名者的身份。提出的方案较好地解决了基于身份指定验证者签名中的密钥托管问题。与同类方案相比,签名和验证次数少、交互次数更少。
A leakage-resilient designated verifier blind proxy signature scheme is presented. It has the properties of anonymityand traceability on the proxy signature. After the proxy signature had been verified, only the signature from delegation ofthe original signer can be confirmed by the verifier, on the other hand, the identity of the proxy signer can not be known atthe same time. In appearing of disputation, the verifier can reveal the real identity of the proxy signer with the help of theKDC. The proposed scheme partially solves key escrow problem in identity-based designated verifier signature. Comparedwith the existing proxy signature schemes, the scheme had less computation and fewer interactions in signature issuingand verification phase.
