<p>An authentication method and an authentication system are provided, which are used to authenticate a handover to a base station for a mobile terminal node, the method includes steps that: an access router of the first base station receives an authentication request from the mobile terminal node, the authentication request contains the first hash value and a media access control address of the mobile terminal node, the first hash value is obtained by looking up a locally preset mobile buffer list by the mobile terminal node according to the base station identifier of the second base station, the mobile buffer list contains the first hash value and the base station identifier; the access router looks up a locally preset access buffer list based on the media access control address to obtain the second hash value, compares the first hash value obtained from the authentication request with the second hash value, and the authentication successes if they are equal, in which the access buffer list contains the second hash value and the media access control address. The question that the mutual authentication efficiency is low during the handover for the mobile terminal node and the access router can be solved.</p> |
