Safe E-mail system

Abstract

The invention discloses a safe E-mail system. The safe E-mail system is characterized in that a client side service module is used for client side encryption and decryption of mail contents and mail attachments, mail signature and communication with a server service module; a client side hardware crypto module is called by the client side service module to complete corresponding code computation; a server side service module is used for receiving connection with the client side service module to complete identity authentication and service processing requests; a server side hardware crypto module is called by the server side service module to complete key exchange and user management; a mail server is called by the server side service module to complete mail transmission and mail storage; and a database is called by the server side service module to achieve storage of system information and data. The safe E-mail system achieves confidentiality, integrity and non-repudiation of mail information in the process of mail transmission by utilizing data encryption technique, and the confidentiality of the mail information is guaranteed due to the fact that a symmetrical encryption structure is used in the safe E-mail system for encryption processing of the mail information.
