摘要
认证邮件协议的目的是实现邮件m与收到该邮件的收据之间的公平交换,认证邮件协议满足的最重要的性质是公平性。基于修改过的W-B签密方案,该文设计出一种带有离线的、透明可信的第三方认证邮件协议。与同类协议相比,在通信量相同的情况下,该协议具有更小的计算量和更高的执行效率。
A certified e-mail protocol is about fair exchange of a message m for its receipt. Fairness is the most important property in exchange. We modify existing W-B signcryption scheme so that it can be used by certified e-mail protocols, and based on the modified scheme we propose a new certified e-mail protocol. The protocol makes use of an off-line and transparent trusted third party only in exceptional circumstances, and has lower computation overhead and better efficiency comparing related protocol.
