Abstract

Abstract:

In recent years, problems such as email leaks have emerged one after another, which have caused a very bad impact. In order to solve the security problem during mail transmission, this paper designed a mail encryption system based on SM9 algorithm according to the national encryption standard of China. The system consisted of four parts: key generation and key distribution, email encryption and decryption, email signature, and key exchange. It could realize the email encryption transmission, email integrity verification, email signature, and key negotiation, etc. It effectively ensured the security of the mail during the transmission process. The email encryption system solved the problems of key spoofing and man-in-the-middle attacks in the traditional email encryption system, and ensured the authenticity and reliability of the public key. It had advantages over traditional email encryption systems.

Key words: E-mail system, asymmetric encryption, SM9 algorithm, identity-based encryption
