Secured communications in cognitive radio networks

Enabling end to end secure communications between source and sink is significant for many Cognitive Radio Networks (CRNs). While there have been many works devoted to hop by hop secure communications, the issue of end to end secure communications is largely ignored. In this paper, an end to end secure communication protocol in randomly deployed CRNs is designed. Specifically; this protocol is based on a methodology called differentiated key pre-distribution. The core idea is to distribute different number of keys to different nodes to enhance the resilience of certain links. This feature is leveraged during routing, where users route through those links with higher resilience. Using rigorous theoretical analysis, an expression for the quality of end to end secure communications is derived and uses it to determine optimum protocol parameters. Extensive performance evaluation illustrates that the proposed solution can provide highly secure communications between relays and sink in randomly deployed CRNs.
