The Design of Trusted Access Scheme Based on Identity for WiMAX Network

To enhance access security capability of WiMAX (Worldwide Interoperability for Microwave Access), a trusted access scheme based on identity is proposed in this paper. It adopts trusted access architecture which includes three layers: identity layer, evaluation layer and authentication layer. Firstly, every entity is assigned only an identity in the identity layer; secondly, credible attribute of the entity is evaluated in the evaluation layer; lastly, authentication layer judges the evaluation results that evaluation layer refers. The scheme uses biology authentication and mutual authentication, then controls access of the user or terminal and chooses the service strategy of service side. Security analysis indicates that the scheme can prevent unlicensed user access, unlicensed terminal access, unlicensed base station attack and message modification.
