Cognitive Radio Sensor Networks (CRSNs) enable efficient spectrum utilization by allowing secondary users (SUs) to opportunistically access unused licensed spectrum bands. Cooperative Spectrum Sensing (CSS) ensures accurate detection of spectrum availability by leveraging collaborative sensing to mitigate individual sensing inaccuracies. However, the collaborative nature of CSS makes it vulnerable to security threats such as malicious user attacks and spectrum sensing data falsification, which can degrade network performance. This paper presents a review of Secure Cooperative Spectrum Sensing (SCSS) frameworks for CRSNs, emphasizing their role in enhancing sensing accuracy while ensuring resistance to malicious interference.

摘要

Cognitive Radio Sensor Networks (CRSNs) enable efficient spectrum utilization by allowing secondary users (SUs) to opportunistically access unused licensed spectrum bands. Cooperative Spectrum Sensing (CSS) ensures accurate detection of spectrum availability by leveraging collaborative sensing to mitigate individual sensing inaccuracies. However, the collaborative nature of CSS makes it vulnerable to security threats such as malicious user attacks and spectrum sensing data falsification, which can degrade network performance. This paper presents a review of Secure Cooperative Spectrum Sensing (SCSS) frameworks for CRSNs, emphasizing their role in enhancing sensing accuracy while ensuring resistance to malicious interference.
