New Security Level of Authentication and Key Agreement Protocol for the IoT on LTE Mobile Networks

Nowadays, systems communications have evolved greatly and creating a new ecosystem with appearance of a high variety of objects, which are able to communicate with each other. The convergence of the cellular networks is raising a new concept called Machine-to-Machine (M2M) communication, which are the most popular application for the Internet of Things (IoT). The future IoT causes different challenges among them we can cite the security of communication and privacy of users. The standard authentication and key agreement protocol (EPS-AKA) normalized by the 3rd Generation Partnership Project (3GPP) in Long Term Evolution (LTE) system is proposed to provide the authentication service between the device and the network. However, this protocol does not support IoT objects and has some issues, including security attack vulnerabilities and traffic overload due to control message. In this article, we propose a new security level of authentication protocol that satisfies the security requirements by providing protection against several attacks, reducing bandwidth consumption by optimizing the authentication messages and secures an efficient communications among various IoT devices. Simulation results showed that the proposed when compared to existing protocols offers better performances in terms of security, overhead and computations delay.
