A Study of Authentication Protocols in Internet of Things

Internet of Things(IoT) is a promising technology in the current era, and security is one amongst the significant challenges in its success. The resource constraints in devices make the design and implementation of counter security mechanisms more challenging. Many attacks from an eavesdropper may endanger to authentication and lunch further attack to IoT systems. Hence, there is a need for an efficient authentication mechanism to withstand all possible known attacks. This study discusses the recent research on lightweight authentication protocols and compares them on various security parameters. In addition, the study also enumerates the various research issues related to the efficiency of authentication mechanisms in IoT. The study also discusses the possible solutions for authentication.
