“…To secure CR networks, several PLS solutions have been developed. For instance, in [93], a spatiotemporal diversification (i.e., moving target defense (MTD)) mechanism was proposed to secure the transmissions of SUs in different eavesdropping scenarios. The idea was to scatter the transmitted signals across space and benignly inject spurious data, thus Feasible transmit power range design + derive optimal power allocation strategy.…”

Fifth-generation and beyond (5G and xG) wireless networks are envisioned to meet the requirements of various vertical applications that require higher traffic throughput, ultra-massive connectivity, extremely low latency, and high quality of service. Disruptive technologies, such as massive multiple-input multiple-output, millimeter wave, and multiple access are being deployed to meet these requirements. However, the deployment of these technologies poses several challenges, including the lack of network transparency, management decentralization, and reliability. In addition, the heterogeneity of these networks raises security concerns, particularly, confidentiality, privacy, and trustworthiness. Typically, networks rely on encryption techniques at higher layers to ensure security and privacy. However, due to the emergence of novel computing paradigms, such as quantum computing, traditional security approaches are no longer sufficient to protect over-the-air communications. Therefore, 5G/xG networks must consider smarter and more efficient security techniques to operate seamlessly and efficiently. Within this context, physical layer security (PLS) and blockchain represent promising solutions to complement existing methods. By exploiting the characteristics of wireless links, PLS can enhance the security of wireless communications, while blockchain can guarantee the decentralization, integrity, and trustworthiness of networks. Motivated by these technological advancements, this paper provides an in-depth review of the existing literature on PLS and blockchain. Then, for the first time, we present a framework for the integration of PLS with blockchain in 5G/xG systems. We begin by providing a thorough discussion about the potential of PLS and blockchain for 5G/xG systems. Next, we present our vision of a cross-layer architecture that leverages both PLS and blockchain in 5G/xG networks. Finally, we identify related challenges and open issues and shed light on future research directions.

The highly dynamic nature of cognitive radio (CR) systems and their stringent latency requirements pose a major challenge in the realization of efficient intelligent transport systems (ITS). In this paper, we investigate relay selection and opportunistic spectrum access in conjunction with blockchain technology in a secure manner. Specifically, we propose a cross-layer method for secure relay selection, where secondary relays (SRs) are granted access to available spectrum bands based on the balance of their respective virtual wallets. These virtual wallets, which are built based on the SRs' secrecy capacity and their behavior in the network, are the predominant factors that allow SRs to participate in an auction model. To quantify the trustworthiness of the SRs, we formulate a mathematical framework to evaluate the trust value of each SR, which is then leveraged for rewarding or penalizing the SR. Furthermore, we develop an offline blockchain framework to store the information of participating relays and make it available for future operations, in order to detect reputable and non-reputable relays in the presence of multiple eavesdroppers. The stored reputations of the participating relays are used to develop a self-learning algorithm to exclude the non-reputable relays from the selection group. Finally, we present thorough numerical results to demonstrate the superiority of the proposed system in terms of security, credibility, and integrity.
