On PHY-layer security of cognitive radio: Collaborative sensing under malicious attacks

Abstract

In cognitive radio networks, physical layer spectrum sensing plays a key role in helping cognitive radios adapt to changes in spectrum availability. However, it raises significant security issues at the physical layer as well. In this paper, we investigate collaborative sensing of cognitive radio networks under malicious attacks, and analyze the system… (More)
