Wireless sensor network are the foremost module of IoT that gather information from the surroundings and send the data to the destination. Internet of Things (IoT) allows communicating with sensor devices in the remote area. It is growing rapidly in business since it provides most valuable service with less cost. In addition to that it makes most advancement in IT resources. A sensor plays a major role in IoT which sense the environment and transmit information to other devices. IoT is built on internet so it contains new kind of challenges like security and privacy. Here major issue which occurs is security of data transmission between nodes. Though several secure algorithms were invented for providing secure transmission each of them have some drawbacks. Traditional security algorithms works fine for wired and wireless network but when it is applied in IoT devices it consumes more energy and ultimately it becomes major problem with battery assisted IOT devices. As IoT operates in different standards and different communication stacks involved traditional encryption algorithms cannot be applied directly, it requires many modifications. This chapter provides a comprehensive discussion on security technologies for WSN using IoT. A brief discussion on the future direction of research in IoT based WSN security is also included.
