电子邮政签名系统的设计与实现

THE DESIGN AND IMPLEMENTATION OF SIGNATURE SCHEME FOR ELECTRONIC MAIL

本文设计与实现了一个基于RSA密码体制的电子邮政签名系统,该系统的签名具有传统书面签名同样的法律效力:收方能够对公正的第三者证明其报文内容是真实的,而且是由那个发方发出的;发方事后不能根据自己的利益来否认报文,而且收方事后也不能根据自己的利益来伪造报文或签名。系统运行表明:达到设计要求。

A signature scheme for electronic mail based on RSA public key cryptosystem is designedand implemented in this paper. Electronic signatures furnish the parties with two forms ofprotection, where A is the originator and B the receiver of a message. That is, 1) Both PartyA and Party B should be protected against forged messages and being planted in the commu-nication system by a third party who pretends to be party A; 2) Party A should be protectedagainst messages forged by party A. The design requirement is found achived by running thesystem.
