Embodiment

[0036] Using double EAP authentication, an MS uses the embodiment of the initial access process of the method proposed by the present invention, refer to figure 2 , its main steps include:

[0037] 1) MS and Authenticator exchange authentication policies through BS;

[0038] 2) The Authenticator selects the authentication method, and sends an authentication request AuthRelay_EAP_TRANSFER message to the MS through the BS, including information such as EAP-Request / Identity;

[0039] 3) After receiving the EAP_TRANSFER (EAP-Request / Identity) message, the MS replies to the Authenticator through the BS with EAP_TRANSFER (EAP-response / Identity), and reports the identity required for authentication;

[0040] 4) When the Authenticator receives the MS EAP-Identiy, it sets the state of the Diameter authentication state machine to IDLE, and the initial value of the first-round authentication success flag is False; and constructs a DER message according to the received MS EAP-payload. ...

Abstract

The invention discloses a method for realizing the respective authentication of a user and equipment by adopting a Diameter protocol. An authenticator sets the initial state of a Diameter client authentication state machine as IDLE; the authenticator constructs a corresponding DER message according to an attribute value related to the MS authentication, and sends the DER message to an AAA authentication server; the authenticator analyzes a DEA message when receiving the DEA message from the AAA authentication server, and the first round of authentication is successfully finished if the analyzed DEA message contains the attribute value which is successfully authenticated; a mark for the first round of successful authentication is set as TRUE; the authenticator constructs a corresponding DER message according to an attribute value related to the MS authentication, and sends the DER message to the AAA authentication server; the authenticator analyzes a DEA message when receiving the DEA message from the AAA authentication server; and if the analyzed DEA message contains the attribute value which is successfully authenticated, the authenticator is changed into an open state, and the authentication is finished. The method can support both single authentication and double authentication; and the method can support the double authentication through slight modification based on the prior diameter authentication state machine, and has backward compatibility.

Description

technical field [0001] The invention relates to a communication system, in particular to a method for implementing user and equipment separate authentication (Double EAP) by adopting a diameter protocol in a mobile Wimax system. Background technique [0002] Four authentication methods are defined in the latest version 1.0.0 of Wimax's network structure specification: user authentication: User single EAP; device authentication: Device Single EAP; simultaneous user and device authentication: User / Device Single EAP; user and device respectively Authentication: Double EAP (two EAP procedures are performed). [0003] The method of user and device authentication (that is, double EAP) requires two rounds of authentication: the first round of device authentication, and the second round of user authentication. If the authentication of the user (User) and the mobile station (MS) needs to be performed separately, the way of double EAP can be selected. A typical application scenario ...
