LTE based C-IoT Network Security Issues and Protocols

Abstract

Cellular Internet of Things (C-IoT) is a new concept for devices connectivity through a dedicated cellular network backhaul. The development of the C-IoT can be added more flexibility and capability to the existing IoT network. As the increase in the cellular and wireless traffic, it leads to the data insecurity issues of the system. Here, we discuss the LTE based C-IoT network and discuss different security and authentication related issues to this system. The current security protocol which is used for present IoT system is not enough to secure all the layer of cellular IoT and also the communication overhead is much high. The proposed Multi-level Authentication and Key Agreement Protocol (ML-AKA) focus on threats generated by all the layer of the IoT starting from application to the core network layer. This proposed protocol is authenticated and validated by AVISPA tool and ProVerif Automatic Cryptographic Protocol Verifier tool and the simulation result shows that ML-AKA protocol is safe from attacks and comparison done after testing, the ML-AKA protocol takes less communication overhead than the others existing protocols.
