Lightweight mutual Authentication Protocol for IoT devices using Elliptical Curves

The Internet of Things (IoT) has now permeated every aspect of modern life, requiring that all things be connected to one another and to the Internet using proper protocols. IoT, being an essential component of today's smart society is experiencing enormous problems from various security and interoperability attacks. Traditional encryption is unsuitable for low-cost IoTs because they are vulnerable to physical attacks. This paper proposes Lightweight mutual Authentication Protocol for IoT devices based on hash function using Elliptical Curve approach in which mutual authentication between RFID Tag and Reader is established through several rounds of communication. We also compare the proposed approach of authentication at both ends (Tag and Reader) in terms of efficiency and security.
