An Efficient Genetic Based Broadcast Stateless Group Key Management Scheme with Dynamic Rekeying in Mobile Ad-Hoc Networks

Abstract

This paper addresses the issue in managing a group key among dynamic group of nodes in Mobile Ad hoc Networks (MANETs), where the participants frequently miss the group key update, commonly known as rekeying. In this paper, we propose a broadcast stateless and distributed Group Key Management framework: Genetic based Group Key Agreement scheme, for supporting dynamic rekeying mechanism in MANET. The rekeying scheme operates with hash functions and Lagrange interpolation polynomial implementation over finite area for group key establishment. Moreover, to provide a strong security mechanism, a revocation system is presented to gather accurate rate of node misbehaviours. The simulation results show that the proposed group key management scheme achieved higher performance and security compared with other existing key management schemes. Moreover, the scheme detects both selfish and malicious attacks fairly at lower overhead.
