不可追踪的盲签名和多重盲签名方案

Untraceable blind signature and multi-blind signature scheme

盲签名是指签名者不知道任何有关签名的信息,可以保护接收者的隐私,因此在电子支票支付等实际应用中有一定应用价值。于是设计了一种新的不可追踪的盲签名和多重盲签名方案,该方案不需要利用hash函数,只需要引入一个随机数,计算量较小,具有一定的实用价值。

Blind signature is that a signer don＇t known any information about the message signed by his/her. It can keep the privacy of the receiver in a proper environment, so it can he put into practice in the application of e-check payment. This paper proposes a blind signature and multi-blind signature scheme. The scheme needn＇t to use the Hash function, only need to introduce one random number, and the computation quantity is greatly small, so it has some practicality.
