E-mail IBE (identity based encryption) system aiming at OWA (outlook web access)

Abstract

The invention relates to an OWA (outlook web access) e-mail IBE (identity based encryption) system applying a pseudo-RSA (Rivest, Shamir and Adleman) digital certificate. The system comprises an OWA client, the pseudo-RSA digital certificate, an IBE cryptogrammic module, a pseudo-RSA digital certificate issuing tool or system, an Exchange server, an AD (advertisement) server, an IBE public key acquisition agent and an IBE secret key server, wherein the IBE public key acquisition agent is an HTTP (hyper text transport protocol) agent or plugin arranged or inserted in an HTTP transmission channel between the OWA client and the Exchange server; the HTTP agent or plugin stops a request of the OWA client for acquiring public keys of encrypted digital certificates of an encrypted e-mail sender and an encrypted e-mail receiver from the AD server by Exchange and generates or returns pseudo-RSA digital certificates or pseudo-RSA public keys of the e-mail sender and the e-mail receiver, so that e-mail IBE encryption based on the OWA is realized, and the manual operation involved in the application of the pseudo-RSA digital certificates in the OWA is reduced and simplified.

Description

technical field [0001] The invention belongs to the technical field of information security, in particular to an email IBE (Identity Based Encryption) encryption system for OWA (Outlook Web Access), which enables the OWA system that does not support IBE encryption to be implemented without modification Email encryption system for IBE encryption of emails. Background technique [0002] The current encryption algorithm can be divided into two systems: Symmetric key encryption (Symmetric key Cryptography) and asymmetric key encryption (Asymmetric Key Cryptography); correspondingly, encryption technology is divided into symmetric key encryption technology and asymmetric key encryption technology technology. In symmetric key encryption algorithm (technology), the same key is used for data encryption and decryption; in asymmetric key encryption algorithm (technology), data encryption and decryption use two different but interrelated keys (a pair of Keys), one of which can be mad...
