摘    要:引入前向安全技术与单向hash链,构造了一种具有时间有效期的安全电子邮件协议.该协议对发送的邮件具有时间有效性,签名所用的私钥具有与时间相关等特点,用不断更新的hash值保证相应的公钥是有效的,以达到邮件签名不可被否认的目的,具有安全性好、稳定性高、实现速度快和实现简单等优点.此协议可用于传送类似合同等带有时间有效期的电子文件.

关 键 词:前向安全技术  单向hash链  安全电子邮件协议  时间相关  有效期  安全电子  邮件协议  VALIDITY  TIME  PROTOCOL  电子文件  速度  稳定性  安全性  公钥  私钥  签名  时间有效性  构造  hash  安全技术

Authors:Li Bin  Zhao Zemao
Abstract:A secure e-mail protocol with time validity was proposed.The forward security technology and one-way hash chain was used in this protocol.The mail to be sent is related to time validity.The private key to be used in signature is also related to time.A hash value updated continuously can ensure corresponding public key is validity,which make the signature of mail is undeniable.This protocol has good properties such as the perfect security,the high stability,quickly and easy to realize and etc.The proposed protocol may be applied to sending electronic file of time validity such as contract file and etc.
Keywords:Forward security technology One-way hash chain Secure e-mail protocol
