Towards a Secure E-mail Protocol with Perfect Forward Secrecy
摘要
Abstract
E-mail has been an important application to transfer the data of communication on Internet. In order to securely and efficiently transfer the E-mail message,many researchers focus on the issues of providing basic encryption function for E-mail protocol or certified E-mail schemes. However, these schemes only meet part of the security requirements for a secure E-mail protocol,and fail to provide a complete solution from the view of a practical secure E-mail protocol. A secure E-mail protocol is defined and proposed for the first time in this paper. In this protocol, the message is encrypted by the short - term encryption keys which are negotiated by the Diffie-Hellman algorithm. The security analysis shows that the scheme not only provides the basic security mechanism but also guarantees the perfect forward secrecy. In addition, this protocol resolves the problems of certification, timeliness and sensitivity,which are strongly needed by a secure E-mail protocol.关键词
