ELECTRONIC MAIL SYSTEM AND METHOD BASED ON CPK SAFETY AUTHENTICATION

摘要

An electronic mail system and a method based on the CPK safety authentication. The system includes an ID certificate module and a protocol module. The ID certificate module is in use as ID for encrypting, authenticating, and signing E-mail when transmission of E-mail, and providing a CPK private key. In the procedure of transferring E-mail, the protocol module uses ID provided by the ID certificate module and the CPK private key to encrypt/ decrypt, authenticate, and validate, and sign E-mail as well as validate validity of signature. A method of safety certification based on CPK E-mail is also disclosed. The solution brings the E-mail system safety, higher efficiency, and more economy.
