Protocol and technology convergence, the core of near future communication, will soon be forming the interoperating heterogeneous networks. Attaining a strict secure authentication without risking the QoS performance and call success rates is a major concern when it comes to wireless heterogeneous networks. In order to achieve this, a generic, fast and secure, authentication and key agreement protocol is to be used; a version of which is to be implemented between each two technologies. In this paper, different existing EPS-EPS AKA protocols will be compared with the authors' proposed protocol EC-AKA (Ensure Confidentiality Authentication and Key Agreement) based on security, cost effectiveness, signaling overhead, delay and performance.
