Abstract: In this paper, we investigate the covertness and secrecy guarantees of wireless communications in an active attacker scenario where attackers perform detection/eavesdropping and jamming simultaneously. Both detection and eavesdropping attacks need to be counteracted, such that the covertness and secrecy guarantees in wireless communications can be achieved. To understand the covertness and secrecy performances, we provide theoretical modeling for covertness outage probability and secrecy outage probability, respectively. Based on the the-oretical model, we conduct theoretical analysis to identify the covert secrecy rate (CSR) under power control (PC)-based secure transmission scheme. Extensive numerical results are provided to illustrate the achievable performances and also reveal the impact of the active attackers on the CSR.
