Secure Collaborative Spectrum Sensing in the Presence of Primary User Emulation Attack in Cognitive Radio Networks
Collaborative Spectrum Sensing (CSS) is an effective approach to improve the detection performance in Cognitive Radio (CR) networks. Inherent characteristics of the CR have imposed some additional security threats to the networks. One of the common threats is Primary User Emulation Attack (PUEA). In PUEA, some malicious users try to imitate primary signal characteristics and defraud the CR user...
متن کاملPrimary user emulation attack in dynamic spectrum access networks: a game-theoretic approach
Cognitive radio enabled dynamic spectrum access networks are designed to detect and opportunistically utilize the unused or under-utilized spectrum bands. However, due to the open paradigm of cognitive radio networks and lack of proactive security protocols, the dynamic spectrum access networks are vulnerable to various denial-ofservice (DoS) threats. In this paper, we propose a game theoretic ...
متن کاملMitigating selfish primary user emulation attacks in multi-channel cognitive radio networks: A surveillance game
Primary User Emulation Attack (PUEA), in which attackers emulate primary user signals causing restriction of secondary access on the attacked channels, is a serious security problem in Cognitive Radio Networks (CRNs). An user performing a PUEA for selfishly occupying more channels is called a selfish PUEA attacker. Network managers could adopt a surveillance process on disallowed channels for i...

متن کاملNEAT: A NEighbor AssisTed Spectrum Decision Protocol for Resilience against Primary User Emulation Attacks
We propose a distributed spectrum decision protocol resilient to primary user emulation attacks (PUEA) in dynamic spectrum access (DSA) networks. PUEA is a type of denialof-service attack that can result in unreliable and/or disconnected DSA networks by depriving legitimate secondary users of spectrum access. We first propose an individual detection mechanism for secondary users to achieve prel...
