Intrusion tolerant communication networks and associated methods

An intrusion tolerant communication network and related methodsis provided that places emphasis on continuity of operation andprovides for an attack-survivable communication network whosenetwork devices collectively accomplish the specified networkingintent even under attack and despite active intrusions. The presentinvention defines methods for network intrusion tolerance in termsof the various state transitions that maximize the overalleffectiveness of an intrusion tolerant communication network.
