“…After inclusion of security mechanisms in the communication system, it is general observation that the energy consumption of the system increases by large amount. As compared to the research work implemented in [15], the fraction of energy savings is slightly reduced with the addition of security in the system. As can be seen from the Figure 9, the energy consumption goes on increasing with the coverage area extension.…”

Spectrum is a scarce and very essential resource for the ever growing mobile communication applications. Radio networks (CRN) is the best evolved solution towards spectrum scarcity. Cooperative spectrum sensing is a well-known and proven mechanism in the CRNs. As compared to other traditional wireless networks, CRNs are more delicate and open to the wireless environments due to their heterogeneous nature. Therefore, the CRNs have more security threats than the conventional wireless networks. The spectrum sensing and sharing mechanisms are inherently vulnerable to the malicious behaviors in the wireless networks due to its openness. This paper proposes an energy efficient lightweight cryptographic Cooperative web of trust (CWoT) for the spectrum sensing in CRNs which is proved to be appropriate for the resource constrained wireless sensor networks (WSNs). Development of trust based authentication and authorization mechanism for the opportunistic large array (OLA) structured CRNs is the main objective of this paper. Received signal strength (RSS) values obtained can be utilized to avoid Primary user emulation attacks (PUEA) in CRNs.

“…The public key is known to all the nodes in the network, whereas individual private key is retained by the corresponding node. Newer key exchange mechanisms for 802.11ae and 802.11af, based on groups have been discussed in the research work published in [15,16,17].…”
