Abstract

In this paper, we propose a group key management scheme for very high confidential information in tactical wireless networks. For the proposed scheme, we consider the tactical networks that has a hierarchical topology and the nature of high confidential information. The leader node, which may have higher probability of good channel state than others, provides some data to all the network member in order to generate a geographical group key and it transmits the encrypted information with minimum transmission power level to others. By this scheme, the security and reliability for sharing confidential information is ensured. The performance of the proposed scheme is validated by mathematical analysis. It shows that the proposed scheme makes nodes to share a high confidential information securely if the proper parameters for network design are selected.
