Surviving in Cyberspace: A Game Theoretic Approach

As information systems become ever more complex and the interdependence of these systems increases, a mission-critical system should have the fight-through ability to sustain damage yet survive with mission assurance in cyberspace. To satisfy this requirement, in this paper the authors propose a game theoretic approach to binary voting with a weighted majority to aggregate observations among replicated nodes. Nodes are of two types: they either vote truthfully or are malicious and thus lie. Voting is strategically performed based on a node's belief about the percentage of compromised nodes in the system.
