A Survey on Security Issues in Wireless Cognitive Radio Networks

PhD Qualifying Examination


Title: "A Survey on Security Issues in Wireless Cognitive Radio
Networks"

Mr. Chengqi Song


Abstract:

Cognitive Radio has been proposed as an advanced technology to make use
of under-utilized wireless spectrums opportunistically, without
interference to licensed users. In cognitive radio networks, wireless
devices do not operate in fixed spectrums, but rather search and find
appropriate spectrums to operate in. To make this advanced technique work
well, some security issues have to be addressed. At first, cognitive
radio networks inherit security problems from general wireless networks,
such as jamming, misbehaviors in routing discovery and data forwarding,
etc. Secondly, cognitive radio networks have some new security problems
because of their special architecture, for example, misbehaviors in
spectrum sensing and analysis, attacks aiming on interference to licensed
users, emulation of licensed users and so on. In this survey, we at first
introduce the building blocks of security in cognitive radio networks,
then propose possible security problems and summarize existing solutions
addressing on them.
