Clustering based trust and group key management for secure communications in MANET

Clustering based trust and group key management for secure communications in MANET In mobile ad hoc network (MANET), clustering without encryption and decryption may result in security issue. In order to overcome this issue, in this paper we propose to develop a trust based clustering and group key management for secure communications in MANET. In this technique, the cluster heads are selected based on the total trust degree and partial trust. Then each cluster member node takes a valid certificate from offline configuration. The cluster member maintains a logic key's tree that includes individual key's tree and a common key. The generated cluster keys broadcasted and member leave and join is handled in the cluster. After sharing the generated group keys with group members, the cluster head generates polynomials and based on which intra group keys are generated for intra-group communication. By simulation results, we show that the proposed technique enhances the network security and offers secure communication. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png International Journal of Services Operations and Informatics Inderscience Publishers

Abstract

In mobile ad hoc network (MANET), clustering without encryption and decryption may result in security issue. In order to overcome this issue, in this paper we propose to develop a trust based clustering and group key management for secure communications in MANET. In this technique, the cluster heads are selected based on the total trust degree and partial trust. Then each cluster member node takes a valid certificate from offline configuration. The cluster member maintains a logic key's tree that includes individual key's tree and a common key. The generated cluster keys broadcasted and member leave and join is handled in the cluster. After sharing the generated group keys with group members, the cluster head generates polynomials and based on which intra group keys are generated for intra-group communication. By simulation results, we show that the proposed technique enhances the network security and offers secure communication.
