Abstract
A method includes receiving an authentication request from a mobile station () and determining whether to forward the request to an authentication agent. When it is determined to forward the request, the request is forwarded to the authentication agent (). A random number and a random seed are received from the authentication agent (). The random number and the random seed are forwarded to the mobile station (). A response to the random number and the random seed from the mobile station () is received and forwarded to the authentication agent (). The authentication agent () compares the response with an expected response. When the authentication agent () authenticates the mobile station (), a derived cipher key is received from the authentication agent ().
