In this paper, we discuss a basic key management protocol togenerate and distribute the keys required for a secure groupcommunication system, which also preserves the backward and forwardsecrecies. We devise a few relaxed policies for rekeying andformulate an enhanced set of protocols for key management. All thecommunications in the protocols are properly authenticated usingElliptic Curve Digital Signature scheme. The relaxed protocolsreduce the number of rekeying to almost 25%, thus saving energy.The security analysis shows that our protocols can withstandseveral possible security attacks especially the serious one, thenode capture attack.
