Security system of Internet of Things based on Subscriber Identity Module

Abstract

There are many security issues in the IoT field and current security solutions can’t provide high security level and cost-effectiveness at the same time. This paper expounds the IoT security service architecture based on Subscriber Identity Module(SIM) card and the key technologies of the service, including bi-directional authentication, secure data transmission and local secure storage. At the same time, it also analyses two modes of the security services, namely simple service mode and self-service mode. With the benefit of SIM, the solution can become a preferred security solution which provides a high security, low-cost, fast implementation and high cost-effective service for the IoT industry.
