| 摘 要： | Nenadic等设计了一个公平的挂号电子邮件协议,协议的目的是实现互不信任的双方以一种公平的方式交换电子邮件和收据并提供发方不可否认证据和收方不可否认证据,这是通过构造一个可验证和可恢复的加密数字签名(VRES)来实现的,由于采用离线TTP,且没有使用零知识证明,效率非常高。该文通过分析指出该协议在构造可验证的加密数字签名时存在缺陷,从而使得它不能保证公平性,并对其进行了修改。 |
| 关 键 词： | 挂号电子邮件协议 可验证的数字签名 协议分析 |

| Abstract: | Nenadic et al.proposed a certified E-mail delivery protocol.The protocol provides strong fairness to ensure that the recipient receives the e-mail if and only if the sender receives the receipt.This is a scheme based on veriable 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 and propose a revised version. |
| Keywords: | certified E-mail protocol verfiably encrypted signature protocol analysis |
