Building an Intelligent Global IoT Reputation and Malicious Devices Detecting System

The Internet of Things (IoT) applications are growing immensely. However, malicious IoT devices are major concerns that threaten the security of IoT applications. This paper proposes an intelligent reputation system for IoT devices using edge computing and cloud computing infrastructures. The proposed system can be used to mitigate the effect of malicious and malfunction IoT devices. Therefore, the proposed system can be used to enhance the effectiveness of IoT based systems such as smart cities, and reduce the risk of malicious IoT devices especially in sensitive systems, such as military applications, that leverage IoT devices. To achieve this goal, the paper proposes a new identification method for uniquely and globally identifying IoT devices wherever they move. Moreover, the paper proposes a new approach for computing the reputation of IoT devices, and calculating correct values based on these reputations. The results show that the proposed approach achieves very good results in detecting malicious IoT devices and computing very close values to the true values.
