Abstract
Group key management in a mobile ad-hoc network (MANET) may be provided. Each network node associated with the MANET may comprise a group distribution key and a list of authorized member nodes from which a group key manager may be elected. The group key manager may periodically issue a new group key to be used in protecting communications among the network nodes. A compromised node may be excluded from receiving updated group keys and thus isolated from the MANET.
