| 摘 要： | 提出了具有新特点的代理签名方案:匿名性和可跟踪性。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,验证者可通过原始签名者揭示代理签名者的身份。这个方案并不需要可信任方参与。

| Abstract: | A proxy signature scheme was presented with the properties of anonymity and traceability. After the proxy signature has been verified, only the signature from delegation of the original signer could be confirmed by the verifier. On the other hand, the identity of the proxy signer could not be known at the same time. In appearing of disputation, the verifier can reveal the real identity of the proxy signer with the help of the original signer. A trusted party isn't involved in the scheme. |
