Effective certificate revocation scheme based on weighted voting game approach

摘要

Mobile ad hoc networks (MANETs) are wireless networks that have a wide range of applications because of their dynamic topologies and ease of deployment. Owing to the independent and dynamic nature of mobile nodes, the topology of a MANET often changes and is prone to various attacks. Therefore, substantial research in the area of security is required. Certificate revocation is an effective mechanism for providing network security services. However, the existing schemes are not well suited to MANETs because of their considerable overhead or low accuracy with respect to certificate revocation. In this study, the authors investigate a distributed certificate revocation protocol. On the basis of the game-theoretic model, they design a new voting-based security scheme. Their game-based security paradigm can provide the ability to practically respond to the current system conditions and is suitable for real MANET operations. Simulation results demonstrate the effectiveness and the efficiency of their scheme with respect to certificate revocation. Finally, they discuss the results of an evaluation provide an outlook on the future work in this field.
