DYNAMIC DELAY TIME DECISION METHOD FOR ENHANCING SECURITY OF THE FORCED LATENCY INTERLOCK PROTOCOL IN INTERNET OF THINGS

Most devices in the Internet of Things (IoT) utilize WiMAX communication, and Femtocells are used to provide reliable communication by eliminating shaded areas where wireless signals become weaker with distance and underground facilities. One downfall of this method is the possibility of eavesdropping through Man-in-the-Middle attacks. Forced latency interlock protocol is used to detect these attacks. This protocol uses a fixed latency value and does not consider packet size and distance. In this paper, we propose a dynamic delay time decision method for reducing the fixed delay time of the forced latency interlock protocol in wireless communications based on the IoT. The evaluation function considers the distance between the device, the packet size, and the bit rate of the broadband internet. The simulation experiments demonstrate the validity of our method, which reduces delay time by an average of 88.19% and increases detection rate by an average of 7.97%.
