Abstract

Cognitive radio based networks can resolve the spectrum scarcity issues present in the current emergency communication networks. Establishing quick and secure communication between rescue team members in the disaster field is a significant task and cognitive radio MANETs are the best choice for disaster management and other emergency situations. This paper presents a scalable group key agreement protocol called ‘ITGECDH.2’ which uses an improved batch rekeying scheme. It is inferred from the performance analysis that the proposed ITGECDH.2 is suitable for secure group communication in emergency cognitive radio MANETs with inherent dynamism as it reduces the number of renewed nodes and incurs reduction in rekeying time.
