On the Security of Cognitive Radio Networks

Security in Cognitive Radio Networks Security in Cognitive Radio Networks

While bringing the potential for solving the spectrum underutilization problem using methods such as dynamic and opportunistic spectrum access, Cognitive Radios (CRs) also bring a set of security issues and potential breaches that have to be addressed. These issues come out mainly from the two important capabilities implemented within CRs: their cognition ability and reconfigurability. This cha...

Cognitive Radio Networks and Security: A Survey

In cognitive radio networks (CRNs), cognitive radio (CR) nodes adaptively access the spectrum aiming to maximize the utilization of the scarce resource. Crucial to the successful deployment of CRNs, security issues have begun to receive research interests recently. This article surveys the research advances in CRNs. First, the fundamentals of CRNs including the basic components (i.e., character...

Spectrum Sensing Security in Cognitive Radio Networks

Title: Spectrum Sensing Security in Cognitive Radio Networks Awais Khawar, Master of Science, 2010 Supervisor: Dr. Charles Clancy Department of Electrical and Computer Engineering This thesis explores the use of unsupervised machine learning for spectrum sensing in cognitive radio (CR) networks from a security perspective. CR is an enabling technology for dynamic spectrum access (DSA) because o...

Security management based on trust determination in cognitive radio networks

Security has played a major role in cognitive radio networks. Numerous researches have mainly focused on attacking detection based on source localization and detection probability. However, few of them took the penalty of attackers into consideration and neglected how to implement effective punitive measures against attackers. To address this issue, this article proposes a novel penalty mechani...
