Abstract
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.
