| 摘要: |
| 代理签名是一种非常有用的密码学工具.使用它,原始签名人能将其数字签名权力委托给代理签名人.在盲签名方案中,消息的内容对签名者是不可见的.签名被接收者泄露后,签名者不能追踪签名.代理签名和盲签名在实际中分别有着广泛的应用.结合两者的优点,在Schnorr签名的基础上,提出了一个代理盲签名方案. |

| Abstract: |
| Proxy signatures are very useful tools with which a potential signer can delegate his signing power to a proxy signer who signs a message on behalf of the original signer. A blind signature is the concept with a salient feature that the signer cannot make a linkage between the blind signature and the identity of the requester. Therefore, it is very suitable for electronic commerce. On the basis of the blind Schnorr signature, this paper presents a digital proxy blind signature scheme, which satisfies the security properties of both the blind signature scheme and the proxy signature scheme. |
