In this paper, we consider the physical layer security issue for the multi-channel full-duplex (FD) communications in the presence of eavesdroppers. There co-exist multiple FD pairs, where the two users in each pair perform bi-directional transmissions. The secure communication is then challenged by the users’ self-interference, external interference from other pairs, and threats from the eavesdroppers...
Information security is a critical yet challenging issue for wireless communications. In this paper, we investigate this problem from a networked perspective. Specifically, we consider a wireless network where there coexists users with and without security concerns, which respectively maximize the secrecy rate and transmission rate. To enhance wireless security, we give the security-oriented user...
Information security is of paramount importance yet significant challenge for wireless communications. In this paper, we investigate the power-efficient transmissions with security concerns in the presence of a full-duplex (FD) active eavesdropper. With FD capability, the eavesdropper can launch jamming attacks while eavesdropping, which affects the legitimate transmissions, such that the legitimate...
Security issue is of paramount importance yet significant challenge for wireless communications, and this problem can be even more intricate when facing with a full-duplex adversary. In this paper, we investigate the physical layer security of a legitimate transmission link in the presence of a full-duplex active eavesdropper, who is capable to perform eavesdropping and jamming simultaneously. The...
Reactive jamming, which performs jamming attacks on condition of detecting the legitimate transmissions, is widely considered as one of the most serious security challenges in wireless communications. In this paper, we tackle the reactive jamming issue from a novel yet realistic perspective -- the jammer may not always be able to accurately detect the legitimate transmissions, which in turn, can be...
