摘要：In the past, Ad-hoc networks were used in limited areas which require secure groupcommunication without Internet access, such as the army or emergencies. However, Ad-hocnetworks currently are widely used in variety applications like group chat, smart applications,research testbed etc. Ad-hoc network is basically group based network in the absence of accesspoint so it is prevalent to provide group key approach to prevent information leakage. When weuse group key approach, we need to consider which group key management method is the mostsuitable for the architecture because the cost and frequency of the rekeying operation remain asan unresolved issue. In this paper, we present analysis about existing group key managementsolutions for Ad-hoc network and suggest a new approach to reduce frequency of the rekeyingoperation.
