Privacy preserving protocol for secure routing in wireless mesh networks

Abstract

In wireless mesh networks (WMN), there are possibilities of lossy links, security attacks and privacy attacks. In order to overcome these issues, in this paper, we propose a privacy preserving protocol for secure routing in WMN. In this technique, when a source node wants to transmit privacy information, it performs a secure routing based on the security level of the nodes. Also, it takes direct and delegation tickets into consideration for secure data transmission. Then, in order to authenticate the access of the mobile users, a tri-lateral pseudonym generation method is used. The mesh client registers its real identity to the operating managers and selects a secret key to generate the pseudonym. By simulation results, we show that the proposed technique enhances the network security.
