Abstract: Internet of Thing (IoT) enhances the heterogeneous communication facility by providing Thing-to-Thing, Human-to-Thing, and Human-to-Human communication schemes. Various kind of threats and vulnerability cause sensor equipped IoT environment at a larger scale. So security and privacy are two important factors that must rely on IoT communication model. IoT network has some capability constraints that affect the deployment of realistic IoT application at a wider level like healthcare system and smart grid, smart city. One of the security concerns of the IoT network is the need of light-weighted encryption scheme. Elliptic Curve Cryptography (ECC) simulation with integrated encryption scheme is the most prominent solution for IoT devices to develop lightweight encryption technology. Here, Optimized Elliptic Curve Digital signature scheme is proposed to achieve secure communication between IoT sensor nodes. The results of optimized ECDSA algorithm are analyzed on Cooja simulator that is a IoT network simulator.
