For existing security problem of user accessing authentication in WLAN,a double-layer authentication model combining negative selection mechanism and positive selection mechanism was proved to improve the security of the authentication.Negative selection mechanism model can identify unauthor-ized users without reading the user information database.The key technologies and processes of the model were given.The experimental results show that the model has higher detection efficiency and is easy to deploy.It has better applicability.
