Efficient and Secure Authentication Handover using Network functions virtualization

Mobility of the subscriber is an important attribute to the success of a telecommunication network. With the advent of 5G networking which achieves high throughput rates by using heterogeneous nodes and frequent handovers, existing authentication and handover techniques should be revisited to securely and reliably perform handovers for LTE LTE. By virtualizing the nodes through Network Functions Virtualization the nodes can be treated as a homogenous node and can be controlled in unison. This greatly simplifies the handover procedure and increases the security of the user specific information. In this article we present our scheme for secure authentication handover in 5G Hetnets
