Efficient Group Key Management Protocol for Region Based MANETs

N. Vimala, B. Jayaram, and R. Balasubramanian

Abstract—Key management in the ad hoc network is an exigent issue concerning the security of the group communication. There are three categories for classifying Group key management protocols; centralized, decentralized and distributed. By establishing key management protocol, suitable solution can be provide to services like authentication, data integrity and data confidentiality. This paper deals with an approach for designing and analyzing the region-based Group key management protocols for scalable and reconfigurable group key management in Mobile Ad Hoc Networks (MANETs). The main issue of centralized key management protocols is about data security on group communication. To overcome this problem a novel approach for key management in Region based MANET is proposed. The Group key establishment comprises creating and distributing a common secret for all the group members. However, key management for a large and dynamic group is a difficult problem because of scalability and security. Modification of membership needs the group key to be refreshed to ensure backward and forward secrecy. In this paper, a Simple and Efficient Group Key (SERGK) management scheme is proposed for Region based MANETs. The proposed method is also effective in defending against many sophisticated attacks such as Denial of service (DoS) attack. In order to preserve the security, the region-based group key management protocols deal with outsider attacks in MANETs. The experimental results compares the computation cost and time for the existing and proposed approach and the results illustrate that the proposed approach outperforms the existing method with lesser computation cost and time.
