Security identification system of wireless application service and login and entry method thereof

Abstract

The invention discloses a safety certification system for wireless application service and the registration and login method. The system comprises a plurality of mobile communication terminals, a business server, a CA certificate server, and a certificate storage server, wherein the mobile communication terminals, the business server and the CA certificate server are orderly connected with each other though the wireless network or wired network, and the certificate server is connected with the business server; the registration method is as follow: a couple of public key and private key are generated by the mobile communication terminal; the registration request is sent to the business server; the registration result is sent back to the business server; the user digital certificate is generated by the OA certificate server, and stored in the certificate storage server; the login method is as follow: the login request is sent to the business server by the mobile communication terminal, and checked by the business server; the checked result is sent back. The invention is characterized in that the public key and the private key are generated by the mobile communication terminal, and protected by the local safety code which is never transmitted in the network. The invention has the advantages of great risk reduction of the public key and the private key acquired, and improved use security of application service in wireless network.
