The Internet of Things (IoT) is an interactive environment, which interconnects material things to the internet and provides advance and intelligent services to a wide range of applications. This kind of complex and dynamic system is often susceptible to attack during data transmission and processing. Therefore, it is essential to know the origin of data and to assure that the source is reliable and the integrity of data is maintained during transmission. However, the limitation on the resources and heterogeneous environment brings several challenges for securing the data in the IoT system. Traditional security solution becomes infeasible because of low energy devices in the IoT system. The purpose of this paper is to present a lightweight security solution for the IoT system by using the Received signal strength indicator. RSSI values would be used to generate the link fingerprint. By comparing the link fingerprints values of various nodes on the server, the presence of adversarial nodes in the system can be detected. This method required very less energy in comparison to the other conventional method.
