“…All the existing physical layer security methods in [3] are classified into five major approaches: theoretical secrecy capacity, multiple-input-multipleoutput (MIMO) channel, coding schemes (channel coding and network coding), power allocation, and signal design (artificial noise). Additionally, cooperative relay [11]- [13], cooperative jamming [14] and energy harvesting [15] are other useful methods. Among the aforementioned methods, cooperative jamming is a promising technique and has attracted significant attention.…”

“…However, these two techniques are adopted separately in most works [11], [12], [32]- [34]. In [12], a scheme with joint cooperative jamming and beamforming is proposed to enhance the security of a cooperative relay network, where part of the nodes uses a distributed beamforming mechanism while the others jam the eavesdropper simultaneously.…”

“…A hybrid cooperative jamming and beamforming scheme is proposed in [34] also; the idea is in both cooperative transmission phases, some intermediate nodes relay the signals to the legitimate receivers by adopting the beamforming distribution, while, simultaneously, the other nodes jam the eavesdropper, which eventually leads in protection of the transmitted data. The authors in [11] develop an optimal relay assignment algorithm to solve the secrecy capacity maximization problem, and a smart jamming algorithm is proposed to increase the secrecy capacity of the system.…”

Abstract-Security has always played a critical role in wireless cooperative communication systems design. Eavesdropping and jamming are two common threats to the information security in wireless networks. However, jamming can be used in a cooperative manner to enable a secure communication link between the legitimate transmitter and the intended receiver. This paper presents a comprehensive survey on different jamming methods used to enhance the physical layer security. This survey outlines first the underlying concept and challenges with respect to security in wireless network design followed by a comprehensive literature review and analysis of jamming techniques with their applications in this field. For each jamming protocol, the paper categorizes different techniques within the existing literature by elaborating on their application, and corresponding performances.Index Terms-Physical layer security, cooperative jamming, beamforming, power allocation, artificial noise, multiple antennas, MIMO, game theory.

“…To maximize the secrecy capacity, the authors of [12] proposed a scheme in which the best channel condition relay is in charge of information relaying, while other relays are in charge of sending jamming signals. The work in [13] considered a more complex model in which multiple sources transmit signals to multiple destinations with multiple relays through a smart jamming algorithm.…”

Secure information exchange occurs in many recently emerging cooperative-based networks, such as 5G networks (especially those with a Device to Device architecture), the Internet of Things, and vehicular ad hoc networks. However, the existing information exchange protocols only focus on either pairwise information exchange or group information exchange, and none of these protocols enable private and public information exchange to occur simultaneously. Thus, a general secure information exchange protocol for a multiuser channel is desirable. With this motivation, this paper investigates simultaneous private and public information exchange in a Multiple Inputs Multiple Outputs (MIMO) multiuser relay channel. In an aim to achieve this goal, signal alignment is chosen as the core technique. With the designed precoding matrix for each user, private information is aligned with its exchange partner, and public information forms a coding chain at the relay. With the aligned private signal and public coding chain, neither an untrusted relay nor external eavesdroppers can recover the original individual information. Performance analyses of the proposed protocol are conducted. First, we conduct transmission performance analyses from the perspective of time slot cost. Second, we conduct a security analysis for private information exchange and public information exchange. Third, we conduct secrecy sum-rate analysis for three attack scenarios: an untrusted relay attack only, an eavesdropper attack only, and both an untrusted relay and eavesdropper attack. The simulations are conducted to demonstrate that the proposed protocol can enable simultaneous private and public information exchange while resisting attacks by an undesired receiver, an untrusted relay, and external eavesdroppers.

“…Specifically, the SC can make the transmission from the source node to the legitimate destination node secure while achieving zero mutual information between the source node and malicious eavesdropper node. Based on this idea, extensive research efforts have been devoted to improving the SC from an information-theoretic perspective under different scenarios, for example, cooperative relaying [12][13][14][15] and beamforming techniques [16,17], cooperative jamming (CJ) methods [18][19][20], and multiple-input multipleoutput (MIMO) schemes [21,22].…”

Cooperative relaying communication is one of the green communication technologies since it shortens the communication distance and saves the transmit power. In this paper, the physical-layer security (PLS) of a multisource multirelay cooperative relaying communication network is investigated by considering the influence of cochannel interference from a security-reliability tradeoff (SRT) perspective. First, the SRT performance is characterized by the outage probability (OP) and the intercept probability (IP). In particular, the IP encountered at the eavesdropper is used to evaluate the security performance, while the reliability performance is analyzed in terms of the OP experienced at the destination. Then, under the impact of multiple cochannel interferers, the intercept probabilities and the outage probabilities of both the conventional direct transmission (DT) strategy and relay selection (RS) strategy are derived in closed-form expressions over Rayleigh fading channels, respectively. Simulation results are provided to validate the theoretical analysis. It is shown that when the OP (reliability) requirement is relaxed, the IP (security) performance improves and vice versa. It confirms that there is an SRT existing between the OP and the IP. Meanwhile, a better SRT performance can be achieved by increasing the number of sources, relays, and cochannel interferers. In addition, it is also shown that the RS strategy generally outperforms the conventional DT strategy in terms of the product of the IP and the OP.
