Fair electronic cash based on untrustworthy trustee

摘要

摘要: 利用RSA盲签名技术,给出了一种基于托管者的公平电子现金协议,重复花费者将以非常大的概率被托管者恢复出其身份。与以前协议不同的是:除非托管者与银行勾结,他无法提取用户的现金,而且托管者只能追踪银行要他追踪的现金,从而最大程度的保证了用户的隐私。该协议还可以追踪可疑的现金和用户,从而可防止和减少电子现金系统的犯罪活动洗钱,勒索等。用户在提取现金时,托管者脱线提供服务,所以效率较高。

Abstract: A fair electronic cash protocol based on trustee is presented by using RSA blind signature technique in this paper, the identity of multi-spender will be revealed by trustee with very high probability. Contrasting with the previous protocol, the users money cannot be withdrawn unless the trustee is in collusion with the bank, and the trustee can only trace the money that the bank asked him to trace. So the privacy of the user can be ensured to the maximum limit. Also this protocol can be used to trace the dubious cash and the owner, thereby it may be exploited to decrease the crimes like money laundering, blackmailing, etc. in the electronic cash system. This protocol requires off-line participation of trustee when users withdraw the cash, so it is efficient for implementation.
