20080288777 | A Peer-to-Peer Access Control Method Based on Ports - A port based peer access control method, comprises the steps of: 1) enabling the authentication control entity; 2) two authentication control entities authenticating each other; 3) setting the status of the controlled port. The method may further comprise the steps of enabling the authentication server entity, two authentication subsystems negotiating the key. By modifying the asymmetry of background technique, the invention has advantages of peer control, distinguishable authentication control entity, good scalability, good security, simple key negotiation process, relatively complete system, high flexibility, thus the invention can satisfy the requirements of central management as well as resolve the technical issues of the prior network access control method, including complex process, poor security, poor scalability, so it provides essential guarantee for secure network access. | 11-20-2008 |
20110055561 | ACCESS AUTHENTICATION METHOD SUITABLE FOR THE WIRE-LINE AND WIRELESS NETWORK - An access authentication method includes pre-establishing a security channel between the authentication server of the access point and the authentication server of the user terminal and performing the authentication process at user terminal and access point. The authentication process includes 1) the access point sending the authentication_activating message; 2) the user terminal sending the authentication server of user terminal request message; 3) the authentication server of the user terminal sending to the user terminal response message; and 4) completing the authentication. | 03-03-2011 |
