Abstract: In this research, an effective smartcard authentication model is developed in the internet of things (IoT) network based on elliptic curve cryptography (ECC). The proposed smart card authentication method has four phases, such as user registration phase, login phase, mutual authentication phase, and password update phase. Initially, the user accesses the real-time information from the sensing node by registering at the gateway node. During the login phase, the smart card is used by the user to login into the system with the supplied. In the mutual authentication phase, a session key is established between the accessed sensing node and the user through the gateway node. Finally, at the password update phase, the legitimate user updates the password without involving the gateway node. The proposed ECC-based authentication scheme is analysed using the metrics, such as detection rate, delay, and throughput for varying number of rounds.
