Research on SSDF Attack and Defense for Cooperative Spectrum Sensing

Abstract

Cooperative spectrum sensing is the core of cognitive radio technologies to utilize spectrum resources effectively. However, cooperative spectrum sensing schemes are vulnerable to abuses by false sensing data, and thus offering opportunities for malicious users. By launching the spectrum sensing data falsification attack, some of them can make a well cognitive radio system useless. To further understand the SSDF attack and its current research situation and development trend, the types of SSDF attack were analyzed in the form of three aspects, and several typical security methods were concluded. Meanwhile, the current problems of SSDF attack and research trends in this area were discussed.
