Indirect Reciprocity Game Modelling for Secure Wireless Networks

The authors formulate the wireless security problem as an indirect reciprocity game, and propose a security mechanism that applies the indirect reciprocity principle to suppress attacks in wireless networks. In this system, a large number of nodes cooperate to reject the network access requests from attackers during the punishment periods. If the punishment time is so long that the cost due to the loss of network services exceeds the illegal security gains of the attack, rational nodes do not have incentive to attack, and hence their system can reduce the attacking probability in the network. They develop a social norm and reputation updating process to build such an indirect reciprocity mechanism for the network.
