ABSTRACT
In this chapter, we propose game-theoretic models for resource allocation in interference channels with physical layer security. Three two-user interference channel scenarios are studied: the peaceful system with public messages, the case with private messages and forward secrecy, and the case with a public feedback channel. These lead to achievable rate, achievable secrecy, and achievable secret-key regions. Next, the outcome of a strategic game in normal form is computed and it is shown that either there exists an equilibrium in dominant strategies or a Nash equilibrium. Finally, three cooperative game models are applied: the Nash bargaining solution, a strategic bargaining algorithm, and the Walrasian market model. They are applicable to all three interference channel scenarios. Numerical illustrations show the utility regions and the outcomes from the different game models are discussed.
