S Ecurity V / S Q O S for Lte a Uthentication and K Ey a Greement Protocol

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 research, different existing EPS-EPS AKA protocols will be compared with our proposed protocol EC-AKA (Ensure Confidentiality Authentication and Key Agreement) based on security, cost effectiveness, signaling overhead, delay and performance. It is proven that EC-AKA is the exclusive protocol satisfying the New Generation Network’s KPIs and it will be promoted as the target generic AKA protocol in heterogeneous networks.
