Privacy Preserving Security Framework for Cognitive Radio Networks
Hyunsung Kim · IETE Technical Review · 2013
AbstractTo address the ever-increasing demand for wireless bandwidth, cognitive radio networks (CRNs) have been proposed to improve the efficiency of channel utilization. CRN permits unlicensed users to utilize the idle spectrum as long as it does not introduce interference to the primary users due to the Federal Communications Commission’s recent regulatory policies. In this article, we first identify the security challenges on CRNs. Then, we present main security issues together with privacy issues on CRNs and provide a privacy preserving security framework as a potential solution. The proposed framework provides a privacy preserving yet accountable security among the CRN entities. Finally, we suggest directions of future work on secure CRNs by describing several open issues.
