A Novel Anonymous Communication Model:Coding Mix
MA Yalei · Journal of Wuhan University · 2011
A wireless network is subject to various security attacks.The present methods of broadcasting,proxy,onion routing and packets mixing are unable to completely adapt the wireless network which has open link,dynamic changes of topological structure and limited resources.In this paper,after exploring the approaches of preventing traffic analysis through hiding the source and destination of packets,we present a novel anonymous communication model named coding mix which is based on the information confusion and the disguising of network coding.This model changes the correspondence and external form of the in and out packets to improve the ability against attacks by coordinating of coding mix on link layer,slicing information on network layer and multipath routing.The new model can achieve the confidentiality and anonymity of the communications and implement the function of the anonymous communications infrastructure.
