Trust and Deception in Hypergame Theory

Hypergame theory has been used to model advantages in decision making. This research provides a formal representation of deception to further extend the hypergame model. In order to extend the model, we propose a hypergame theoretic framework based on temporal logic to model decision making under the potential for trust and deception. Using the temporal hypergame model, the concept of trust is defined within the constraints of the model. With a formal definition of trust in hypergame theory, the concepts of distrust, mistrust, misperception, and deception are then constructed. These formal definitions are then applied to an Attacker-Defender hypergame to show how the deception within the game can be formally modeled; the model is presented. This demonstrates how hypergame theory can be used to model trust, mistrust, misperception, and deception using a formal model.
