Information Leakage Games: Exploring Information as a Utility Function

A common goal in the areas of secure information flow and privacy is to build effective defenses against unwanted leakage information. To this end, one must be able reason about potential attacks their interplay with possible defenses. In article, we propose a game-theoretic framework formalize strategies attacker defender context leakage, provide basis for developing optimal defense methods. novelty our games that utility given by which some cases may behave non-linear way. This causes significant deviation from classic game theory, functions are linear respect players’ strategies. Hence, key contribution work establishment foundations games. We consider two kinds games, depending on notion considered. The first kind, QIF -games , tailored theory quantitative flow. second one, DP corresponds differential privacy.
