Abstract
Internet of Things is found everywhere in today’s life, they are simplifying our life and are reliable. As they are connected to the Internet for communication, they are vulnerable to security attacks. Here, we have proposed a Key generation protocol for Internet of Things (IoT) devices for securing the communication between them. The proposed protocol is based on the discrete logarithm problem (DLP) and is secure. In the proposed mechanism the nodes/entities generate the session key and the communication is facilitated by server. The session key is generated by the individual nodes. The mechanism uses group theory and DLP. As the key is generated by the nodes and no exchange of key is done, the proposed mechanism is secure. It requires very fewer resources and is suitable for IoT networks.
