RSA-CEGD协议的密码分析
Cryptanalysis of the RSA-CEGD protocol
摘要：
最近，Nenadić等人（2004年）提出了关于电子商品核证交付的RSA-CEGD协议。这是一个相对复杂的方案，基于可验证和可恢复的加密签名（VRES），以保证强公平性和不可否认性等属性。在本文中，我们证明了这个协议不能实现公平性，提出了一个严重的攻击，也指出了一些其他的弱点。
英文摘要：
Recently, Nenadić et al. (2004) proposed the RSA-CEGD protocol for certified delivery of e-goods. This is a relatively complex scheme based on verifiable and recoverable encrypted signatures (VRES) to guarantee properties such as strong fairness and non-repudiation, among others. In this paper, we demonstrate how this protocol cannot achieve fairness by presenting a severe attack and also pointing out some other weaknesses.
