Lightweight ECC and token based authentication mechanism for WSN-IoT

The paper deals with Wireless Sensor Networks (WSN) registered in a specific Internet of Things (IoTʼs) network that have different kind of applications. They come into use once they are successfully registered within a specific IoT network. Elliptic Curve Cryptography (ECC) with Token based Security Scheme is proposed here for secured and authenticated communication. A lightweight authentication mechanism is proposed also in order to prevent the network from the unauthorized access. Network nodes are generated with token keys immediately after login, and the gateway generates token ID for each individual nodes. Then elliptical curve cryptography is applied to remove the malicious nodes completely if some adversaries missed out during token key verification process. If the user needs to access the data, he must go through the token key generation and verification phase, as well as through the data integrity and transmission phase.
