A METHOD FOR THE ACCESS OF THE MOBILE TERMINAL TO THE WLAN AND FOR THE DATA COMMUNICATION VIA THE WIRELESS LINK SECURELY

摘要

A method for the access of the mobile terminal to the WLAN and for the data communication via the wireless link securely. Through the combination of the public key technology and the symmetrical key technology, the method can make secure access control for the mobile terminal to the WLAN and overcome the secret localization of the data communication via the wireless link. When the mobile terminal wants to enter the access point, both sides should authenticate the certificate each other. Only when both sides have the legitimate certificate, the mobile terminal can enter the access point. In order to realize the secure data communication, the mobile terminal and the access point consult the secret key for communication together, give a key for each authentication and amend the key in the conversation process. Anyhow, this method not only realizes the access control of the mobile terminal, but also ensures the security of the access control for the mobile terminal and the high privacy of the communication.
