“…Recently, the SOP was studied in [12] under the assumption that the relay is untrusted. In [13], the authors proposed a relay selection scheme for security constrained in the CRNs with an eavesdropper. In [14], the authors proposed four different relay selection schemes to enhance the security in the CRNs, i.e., random relay and random jammer, random jammer and best relay, best relay and best jammer, and best relay and no jammer.…”

In this paper, the secure communication of a cognitive radio network (CRN) over Nakagami-m fading channel is investigated. An underlay protocol is used in the considered network, where the unlicensed users or secondary users (SUs) can operate simultaneously with the primary users (PUs) in the same spectrum bands providing that the transmit power of the SUs is constrained by not only the maximum tolerance interference at the PU's receiver but also the maximum transmit power at the SU's transmitter. The exact closed-form expressions of important secure performance metrics, i.e., secrecy outage probability (SOP) and secrecy capacity (SC), are derived. In addition, to give a deep insight into the secure performance trends, the asymptotic expression of the SOP is also obtained when the average signal-to-noise ratio (SNR) of the legitimate channel is high. It is proven that the considered system achieves full diversity gain regardless of the number of antennas at the eavesdropper. Finally, the correctness of our mathematical framework is verified by Monte Carlo simulations.

“…A centralized control scheme is presented in [16,17], which needs setting a cognitive user as the target user to compare with others, then FC adjudges whether the user is abnormal by iteration. This scheme will bring FC huge amount of computation as N 2 because direct and indirect information interactions have occurred in any of the two or more users.…”

“…Zhang et al in [15] proposed a security scheme based on localized combinatorial keying (LOCK) scheme and employees IDbased secure group key management, which minimizes the number of key storage requirement and the number of the communication messages for rekeying. Sakran et al in [16] proposed a secure relay selection scheme which selects a trusted decode and forward relay to assist the SUs and maximize the achievable secrecy rate that is subjected to the interference power constraints at the PUs for the different number of eavesdroppers and PUs under available channel knowledge in the security constrained CRNs. In [17], Chen et al proposed a game theoretical anti-jamming scheme and modeled the jamming and antijamming process as a Markov decision process.…”

Security has played a major role in cognitive radio networks. Numerous researches have mainly focused on attacking detection based on source localization and detection probability. However, few of them took the penalty of attackers into consideration and neglected how to implement effective punitive measures against attackers. To address this issue, this article proposes a novel penalty mechanism based on cognitive trust value. The main feature of this mechanism has been realized by six functions: authentication, interactive, configuration, trust value collection, storage and update, and punishment. Data fusion center (FC) and cluster heads (CHs) have been put forward as a hierarchical architecture to manage trust value of cognitive users. Misbehaving users would be punished by FC by declining their trust value; thus, guaranteeing network security via distinguishing attack users is of great necessity. Simulation results verify the rationality and effectiveness of our proposed mechanism.

“…Given that relay beamforming is an important method of PLS, this paper mainly researches the CRNPLS transmission problems based on relay beamforming. There is a pair of nodes and some relay nodes in the bibliographies [10,11,12,13,14], but they just select the best one of the relays to transmit signal. Although bibliographies [15,16] mainly concern about CRNPLS transmission schemes with multi-relay collaboration, they concern only the condition of a pair of secondary users.…”

Abstract. To solve the transmission problemof physical layer security(PLS) in relay cognitive radio network (CRN), this paper investigates the PLS transmission scheme of multiple relays CRN, which contains two pairs of secondary nodes without direct link each other. Compared with the model that consists ofa pair of secondary node users and a single relay in terms of theoretical analysis and optimization, the proposed scheme is more complicated. To maximizethe joint secret rate of the secondary users,power allocation of the twosecondarysource transmission node withbeamforming andartificial noise assist (PBNAS) is obtained. Furthermore, exploiting the semidefinite programming theory (SDR) and the successive convex approximation (SCA) method, the original complex nonconvex problem is transformed into a convex optimization problem, and the iterative procedure is summarized.Finally, the security transmission rate versus different number relays andrelays total power is simulated. The simulation results show that the security performance of the PBNAS scheme is the best.
