Secure Communication Between Sensors in IoT

 Wireless Sensor Networks (WSNs) are the foremost module of IoT that gather information from the surroundings and send the data to the destinations. A wide Varity of devices can be included in the IOT. Connecting many stand-alone IoT systems through the Internet introduces many challenges, with security being front-and-center as much of the collected information will be exposed to a wide and often unknown audience. Majority of the existing mechanisms are highly recursive that is actually not feasible for a resource-constraint node to execute for a longer run. Therefore, it will lead to an excessive shortening of resource from the sensor node thereby degrading both communication and security standard. The adversaries acts very differently in wireless sensor networks (WSN) and it has never been checked how they behave when they slipped to internet communication channel. Hence, a robust security scheme is required for securing both gateway node as well as sensor node from being prone to ever increasing level of threats in IoT network and its respective applications. The main aim of this paper is to introduce a secure communication system in IoT.
