讲座题目：Counterintelligence and Its Effects in Games with Conflict of Interest

讲座摘要：We consider the interaction between a Defender with private types and an Attacker. The Attacker benefits from taking an action that matches the Defender’s actual type, while the Defender prefers the opposite. Before taking action, the Attacker receives a noisy signal about the Defender’s type generated either from his own intelligence system or a counterintelligence system covertly designed by the Defender. The Attacker does not know which system generated the signal, but he knows the probability that it comes from the Defender’s counterintelligence system （the “infiltration rate”）. We examine the Defender’s equilibrium design of counterintelligence information and how counterintelligence affects the Attacker’s action choice. We find that the infiltration rate plays a crucial role in equilibrium characterization, and increasing it may reduce the Defender’s payoff. Moreover, counterintelligence does not always benefit the Defender or harm the Attacker.
