Lightweight Authentication Methods in IoT: Survey

In recent years, the Internet of Things has gained prominence as a potential communication paradigm with a wide range of applications, including smart cities, smart homes, and intelligent transportation systems. The information gathered by a variety of IoT smart devices may be safely stored on (cloud) servers. The communication between devices in networks has rendered people unable to communicate with one another due to security authentication challenges such as destruction or abuse of IoT devices. In the Internet of Things, security and privacy are important considerations. This paper conducts a review of existing research in the fields of identity management, lightweight authentication, and authorization that applies to the IoT environment. We sift through modern set of papers, classify them, and highlight current IoT security trends and its performance measures.
