An Efficient Mobility Aware Group Key Management Scheme for Securing Mobile Ad-Hoc Networks

Authors : V.S Janani and M.S.K. Manikandan

Abstract: In Mobile Ad-Hoc Networks (MANET), providing secure communication is extremely challenging due to the dynamic nature and the lack of centralized management. To address this issue, several researchers have proposed various key management schemes to ensure security. In this study, we describe a Mobility aware Group Key Management (MGKM) scheme for secure communication in MANETs. We present a beneficial approach in which members in the network form various groups in the same network region. An effective key tree is deployed to carry out the rekeying operation within each group, when members leave or join. Moreover, we adopt an efficient key generation scheme in order to reduce computational overhead of new keys. A revocation system that unifies direct observations with Bayesian theory and indirect observations with Dempster-Shafer (DS) evidence theory is presented to obtain a more accurate misbehaviour rate of suspicious nodes in MANETs. The proposed scheme is designed to establish a secure dynamic communication between the nodes at different regions. From our experimental results, we revealed that the proposed group key management scheme achieved higher performance and security compared with other existing key management schemes.
