A Novel Secure Session Key Generation using two-level architecture For Cluster-Based Ad Hoc Networks Based On ID-Based Bilinear Paring

In 1997, Ruppe R. et al [17] first proposed a Near-Term Digital Radio (NTDR) network system which is a cluster-based ad hoc network intended to be used efficiently for military missions. In the same year, Zavgren J. [18] proposed a management protocol for the NTDR network system. But they both lack the security considerations. In 2003, Varadharajan et al [4] proposed a secure cluster-based ad hoc network protocol using public key infrastructure (PKI). However, in 2005, Chang et al pointed out that using PKI would be a heavy burden for the computation of each mobile node. Hence, they proposed a protocol [5] based on Diffie-Hellman method for securing network, in the same year, Liaw et al. proposed a secured key exchange protocol [20] for securing nodes communication in mobile ad hoc networks (MANETs). In 2006, also for security purpose, Chang and Lee [6] proposed the other scheme by using nodes’identities. But after our analysis, we find that both of their protocols have some mistakes. Accordingly, we propose a new protocol based on ID-based bilinear pairing to get rid of nowadays unsolved security problem in NTDR network. After our analysis, we conclude that our scheme is not only secure but also very efficient.
