Anonymous Communication in Wireless Mesh Network
Ru Li, Liaojun Pang, Qingqi Pei, Guozhen Xiao · 2009
Wireless Mesh Network (WMN) is vulnerable to passive monitored attacks because of the specific character of wireless channel. The existing security routing protocols of WMN are all the improved ones based on the original Ad hoc network protocols, so it is necessary to design a new security protocol for the specific character of WMN. In this paper the Onion Ring protocol designed by Lee has been analyzed that it cannot defend against a so-called intersection attack, a new type of attack. Based on this protocol, an improved layered Onion ring protocol is proposed which can defend against this attack effectively. Therefore, the proposed protocol is more secure and effective than the existing one.
