一种基于RSA密码体制的盲签名方案

Untraceable Blind Signature Scheme Based on the RSA Cryptosystem

盲签名是一种重要的密码与计算机网络安全技术,它的使用可以保证所传送的信息不被篡改和伪造。在盲签名方案中,消息的内容对签名者是不可见的,签名被泄露后,签名者不能追踪其签名。论文基于RSA密码体制,利用扩展Euclidean算法构造了一种不可跟踪盲签名方案。

Blind signature is very useful tool in crypto and internet security. 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 voting systems and electronic commerce. On the basis of the RSA Cryptosystem, based signature schemes, this paper presents a blind signature scheme using extended Euclidean algorithm, which satisfies the security properties of the blind signature.
