Problems solved by technology

However, this transmission method usually faces high security risks. Illegal crackers can even directly obtain chat records such as pictures and voices by stealing the user's account name and password, thereby wantonly infringing on the user's privacy.
Although users can protect their accounts by regularly changing their passwords, this also means an increase in user costs, and this cannot eradicate the problem of privacy leakage, and there is no security at all

Abstract

The invention provides a mail encryption system based on a domestic commercial cipher code chip and an implementation method thereof. The mail encryption system comprises a system control module, a user data input module, a mail server configuration module, a mail content display module, a data encryption and decryption module and a key management module. The implementation method comprises the steps of sending encryption mail contents and receiving the encryption mail contents. Through encryption of data transmitted and received through mails, the system and method solve the possible problems of data loss and privacy leakage. According to the invention, the texts and the attachments of mails can be encrypted and further the encryption can be performed by using a default key in the system or a user-defined key, so that the security of the mail data of users can be further improved. The system and the method can protect decrypted plain texts and the default security strategy of burn after reading is enabled for attachments, so that the practical application requirements of users having relatively high requirements for personal privacy are met.

Description

technical field [0001] The invention belongs to the technical field of mail encryption systems, and in particular relates to a mail encryption system based on a domestic commercial encryption chip and an implementation method thereof. Background technique [0002] E-mail is a form of communication that provides information exchange by electronic means and is the most widely used service on the Internet. Emails can be in various forms such as text, images, and sounds. At the same time, users can get a lot of free news, special emails, and realize easy information search. The existence of e-mail has greatly facilitated the communication and exchange between people and promoted the development of society. [0003] As a widely used communication method for users at present, email is an indispensable communication channel for almost all Internet users in their life, study and work. Users can transmit text and multimedia with their family, friends and colleagues through email t...
