Method And System For Authenticating Network Device

The present invention provides a method and system for authenticating a network equipment (NE). When the NE is authenticated, the integrity checking result recorded in the trust environment (TE) of the network equipment is added for joint judgment to determine finally whether to initiate the authentication request or to respond with the authentication access. Only when both of the received access authentication request and the integrity checking result recorded in the TE of the network equipment are correct, the NE responds with the authentication success. And only when the integrity checking result recorded in the TE of the NE is correct, the NE actively initiates a valid access authentication request. Thus only when the integrity of the NE is correct, authentication for the NE is passed, therefore the secure authentication for the NE is ensured, and the possibility that the illegal device or tampered device passes the authentication is eliminated.
