NB-IoT Security: A Survey

Abstract

In the past few years, the term Internet of Things (IoT) has become very prevalent. In IoT, aggregation of data (from sensors) to processing the data (to the cloud) is energy constraint. To address this challenge, Narrowband- Internet of Things (NB-IoT) is becoming a popular choice for smart devices manufacturer due to its characteristics of high energy-efficient and long battery life. Researchers and academia have addressed the problem related to energy constraints, but it opens the door for security issues related to NB-IoT devices. In this paper, we have done a survey closely related to security issues related to NB-IoT technologies like RFID, WSN, WoT, and IoT. IoT is enabled with five-layered architectures, and each layer is prone to different security attacks. In this paper, we have provided a comparative analysis of security issues in a layer-based approach. We propose the different possible security attacks like shared node attack, synchronization attack, node failure attack, source code attack, and battery drainage attack associated with NB-IoT. To do the performance analysis of security attacks, related matrix, and their mathematical formulation is based on Secrecy Rate and Secrecy Outage Probability for the smart home application. This paper also raises security issues related to smart health and smart agriculture applications.
