An Efficient Communication Key Management Solution for MANET

An efficient communication key management scheme to mobile ad-hoc networks (MANET) based on the ideas of threshold cryptography is proposed,local-TTP and location-based virtual network infrastructure. The protocol is built upon a combinatorial formulation of the group key management issue. Primary features of the scheme include independently computation group keys by using a hash function and the mapping of nodes for group keys. Also,the proposed scheme scales well and supports dynamic setup and management of arbitrary structures of secure group communication in MANET.
