“…In contrast to the works mentioned above, we not only explore the design of the block structure and consensus algorithm with the goal of resolving the scalability issue with blockchain technology, but we also develop a decentralized energy detection evaluation mechanism and a privacy protection mechanism to maintain the privacy of SUs and the openness of the blockchain system. The authors in [56] suggested a blockchain-based spectrum sensing in order to improve security improvement in CRNs. To the best of our knowledge, this is the first study of a combined privacy protection mechanism and energy detection assessment in a Dynamic Spectrum Access (DSA) system with CSS.…”

In this article, the authors proposed a novel blockchain-oriented location privacypreserving (BoLPP) for the Cooperative Spectrum Sensing (CSS) in 6G networks. In order to attain the sustainability of privacy and security for 6G wireless networks, it is a great challenge in this sensing as it faces various malicious attacks while the secondary user (SU) is active. To tackle these issues, the authors proposed a novel framework for blockchainoriented Cognitive Radio Networks (CRNs) for CSS using an energy detection technique. Moreover, the authors implemented another novel paradigm BoLPP, to attain the privacy of SUs location for CSS in 6G networks. This approach preserves the SUs' location and makes the BoLPP framework immune to all malicious attackers. The simulation results have been undergone based on the performance metrics such as response time, consistency, probability of false alarm, frame loss (%), average network throughput, energy efficiency, and security. The outcomes reveal that the proposed scheme achieves high security, privacy, energy efficiency, average network throughput, and low probability of false alarm and frame loss (%) when compared with the existing frameworks such as Friend or Foe (FoF) and Tidal Trust Algorithm (TTA) mechanisms. It is observed that the proposed BoLPP mechanism provides better security and privacy in 6G wireless networks.
