A Study on Group Based Authentication and Key Agreement Protocols for Communications in 3GPP Networks

Abstract

Communications among machine type devices without human intervention is one of the important objectives of Internet of Things (IOT). It has huge market and several use cases. Inmodern times there ismassive rise in the number of low power and cost, Machine Type Communicating Devices (MTCDs) that have a tendency to connect to the network causing severe congestions in the network thus deterring network’s QOSseverely. To address this issue several researchers had proposed the Group Based Authentication and Key Agreement (G-AKA) protocols where the cluster of such MTCDs isvalidatedat once by the authority, responsible for endorsement in the wireless networks. In these schemes, the authority say Home Subscriber Server (HSS) authenticates the MTCDs simultaneously, and also can establish the self-determining session keys with the autonomous MTCD to be used for further data transmission securely. These schemes have guaranteed the well-organized usage of bandwidth by dropping the congestion levels caused by control signals. In our paper, we have presented comparative analysis of such protocols. In the end, we have also explored its future scope and its potentiality in easing the network load considerably.
