Distributed Hierarchical Group Key Management using Elliptic Curve and Hash Function

Key management is an essential cryptographic primitive upon which other security primitives are built. However, there are many existing key management schemes that lack on some points and those are not much suitable for ad hoc networks. In this paper we are going to present a distributed hierarchical group key management approach that uses Elliptic Curve Cryptography and Hash function for secure generation and distribution of group key.
