Tree Based Group Key Agreement - A Survey for Cognitive Radio Mobile Ad Hoc Networks

Abstract

Cognitive radio networks solve the spectrum scarcity problem by dynamically utilizing the unused spectrums. To ensure secure and reliable communication, cognitive radio mobile ad hoc networks require more stringent and secure protocols due to their intrinsic nature. Tree based topology for cognitive radio network is widely used as it takes less time for join and leave operations for the users within the channel of the spectrum compared to other topologies. This paper presents a survey of tree based group key agreement schemes applicable to cognitive radio networks. © Springer International Publishing Switzerland 2014.
