A Cooperative Jamming Scheme for Secure MUAS Control at Edge Using Kriging-Based REM

Multiple unmanned aerial vehicles (UAVs) are growing popular in civil and military scenarios, especially for their significant contributions to mission performance under high level of autonomy (LoA). However, autonomous cooperation at edge demands stronger security to the flying ad hoc network (FANET) that supports control-related data transmission among UAVs. In this paper, we investigate the confidentiality of data transmission in FANET from a physical layer security (PLS) perspective, and introduce cooperative jamming (CJ) against possible eavesdropping attacks. To estimate CJ efficiency in a partially known wireless environment, we design a self-detection based approach to evaluate the wireless conditions by using the Ordinary Kriging method to integrate limited channel state information. Further, we propose a CJ control scheme to balance the trade-off between security level and wireless energy consumption. By simulations, we evaluate the proposed schemes under different wireless conditions and compare them with other possible solutions.
