In the modern information society, when the email is popular, the security problem is also very prominent. In fact, the process of e-mail transmission is the process of repeated replication on the network, the network transmission path is uncertain, it is easy to be unknown identity of the theft, tampering, and even malicious destruction, to send and receive both sides trouble. Information encryption to ensure the security of the transmission of e-mail has become an urgent demand for the vast number of e-mail users. The appearance and application of PGP solves the problem of secure transmission of e-mail well. Combining the traditional symmetric encryption with the public key method, we have two ...

1 Introduction e-mail plays an important role in people's work. According to statistics, the average Chinese per user receives 4.4 mails a week, sends 3.6 emails. But the primary protocol for e-mail, such as SMTP, is delivered in plaintext. This information may be obtained by a third party when it passes through an untrusted internet. In a modern society that attaches importance to information security, it clearly meets the requirements. How can this information be kept confidential without tampering or forgery? The PGP (Pretty-Privacy) described in this article is a kind of software, which is mainly used for electric ...
