Abstract

The invention provides a comprehensive defense secure e-mail system. The system comprises a secure e-mail sending client used for generating an encryption key; an e-mail security center used for scheduling an encryption algorithm to encrypt a sent e-mail and meanwhile scheduling an IBC encryption algorithm to encrypt the encryption key through a receiver e-mail address; and a secure e-mail receiving client used for scheduling an IBC decryption algorithm to decrypt the encryption key and scheduling a corresponding decryption algorithm to decrypt the e-mail. The comprehensive defense secure e-mail system provided by the invention adopts the IBC technology, the sand box technology and the reputation technology to form a joint e-mail box security defense system, which can effectively resist junk mails, Trojans, viruses, ATP attacks and the like and achieve multi-protection of login security authentication, transmission encryption and secure storage and the like of the e-mail system.

Description

technical field [0001] The invention relates to the security application field of emails, in particular to a comprehensive defense security email system jointly constructed by IBC technology, sandbox technology and reputation technology. Background technique [0002] The application of e-mail has brought great convenience to people's work, study and life, making the transmission of information between people faster and more convenient.
