this study aimed at identifying critical factors affecting the security of iranian football stadiums and prioritizing them using the analytical hierarchy process (ahp) for future decisions. in the qualitative stage of the study, the main factors affecting the security of iranian football stadiums were identified in 12 semi-structured interviews with experts. in the quantitative stage, 17 expert...

A multiobjective security game problem with fuzzy payoffs is studied in this paper. The problem is formulated as a bilevel programming problem with fuzzy coefficients. Using the idea of nearest interval approximation of fuzzy numbers, the problem is transformed into a bilevel programming problem with interval coefficients. The Karush-Kuhn-Tucker conditions is applied then to reduce the problem ...

In today's highly interconnected networks, security of the entities are often interdependent. This means security decisions of the agents are not only influenced by their own costs and constraints, but also are affected by their neighbors’ decisions. Game theory provides a rich set of tools to analyze such influence networks. In the game model, players try to maximize their utilities through se...

Abstract-The traditional target of computer game security is mainly copy protection. The emergence of online games fundamentally changes the security requirements for computer games. Although computer game development often utilizes the cutting edge technology in computer graphics, artificial intelligence, human computer interaction and programming, game providers (developers or operators) do n...

This chapter provides a comprehensive review of the domain of game theory based physical layer security in wireless communications. By exploiting the wireless channel characteristic and secure cooperation of nodes, physical layer security is to enable the exchange of confidential messages over a wireless medium in the presence of unauthorized eavesdroppers, without relying on higher-layer encry...
