Research on Cognitive Radio Spectrum Sensing Security Mechanism Based on Blockchain

Abstract

Abstract In cognitive wireless networks, the collusion attack of malicious users has brought great challenges to the safety perception of the spectrum. Based on the analysis of the characteristics of existing attacks, a hypothetical analysis of possible attack behaviors, and the effective combination of blockchain technology and existing mechanisms are introduced, and a new secure spectrum sensing method based on blockchain technology is proposed. This method can treat the user’s historical interaction as a public ledger, and effectively monitor the user’s collusion attacks.
