“…If Eve knows that Alice and Bob insert jamming samples into their own Tx signals as given in (7), the receiver structure of Eve is equivalent to that in Figure 4 except for not exploiting the "Digital SI Canceller" block. From (18) and (19), we obtain ȳ e = [ȳ e (0), … ,ȳ e (L a − 1)] T , where from which we have The processes undertaken by Eve to wiretap the confidential information of Bob are equivalent to those in (16)- (21), except that y e in (16) is modified by When Eve eavesdrops on the data transmitted by Alice, the Tx signal of Bob received at Eve is treated as background noise.…”

“…As studied in [7][8][9], a legitimate receiver operating in IFD can transmit a jamming signal while receiving the information transmitted from a legitimate transmitter. In the presence of an adversary exploiting IFD for both eavesdropping and jamming attack simultaneously, [18] and [19] studied strategies to maximize the secrecy capacity by minimizing the effects of the jamming attack. In [10][11][12][13], IFD is applied in a bi-directional IFD (BD-IFD) communication environment where two legitimate users operating in IFD exchange their data.…”

“…This is because the in-band STR in a multiuser environment causes co-channel interference (CCI) between communicating users [5], or between a backhaul link and an access link [6]. However, from a PHYSEC perspective, the CCI yielded by the in-band STR of IFD can be used to protect the information of legitimate users from eavesdropping [7][8][9][10][11][12][13][14][15][16][17][18][19]. As studied in [7][8][9], a legitimate receiver operating in IFD can transmit a jamming signal while receiving the information transmitted from a legitimate transmitter.…”

In this paper, we describe a simultaneously transmitted jamming (ST‐jamming) for bi‐directional in‐band full‐duplex (IFD) system to improve information security at the physical layer. By exploiting ST‐jamming, each legitimate user transmits data samples and jamming samples together in one orthogonal frequency division multiplexing symbol according to given traffic asymmetry. Regardless of the traffic difference in both directions in IFD communication, eavesdropping of confidential information is prevented in both directions simultaneously without the loss of data rate. We first propose an encoding scheme and the corresponding decoding scheme for ST‐jamming to be used by the legitimate users. In addition, we study a transceiver structure of the legitimate users including a baseband modem uniquely designed for the use of ST‐jamming. The leakage of confidential information at an eavesdropper is then quantified by studying the mutual information between the confidential transmit signals and the received signals of the eavesdropper. Simulation results show that the proposed ST‐jamming significantly reduces the leakage of legitimate information at the eavesdropper.

We propose a robust resource allocation framework to provide physical layer security for a multiple input single output (MISO) communication system. In the considered system, we assume that the both legitimate receiver and eavesdropper are in full-duplex (FD) mode and compare the corresponding performance to conventional cooperative jamming frameworks where a half-duplex (HD) receiver is at hand. In the present paper, the adversary intends to optimize its transmit and jamming signal parameters so as to minimize the MISO secrecy rate between the legitimate transmitter and receivers. The proposed self-protection scheme eliminates the need for external helpers and provides system robustness. Moreover, we investigate robustness against channel state information uncertainty. Optimal power allocation is obtained based on worst-case secrecy rate maximization, under legitimate transmitter power constraint in the presence of an active eavesdropper. Numerical results are then provided to confirm the advantages of using FD receivers.
