SECURE NETWORK CODING SCHEME AGAINST WIRETAPPING ATTACK BASED ON ROUTE SELECTION
摘要
Abstract
Compared with the traditional network theory based on route, network coding technology has lots of characteristics and advantages.At the same time, it also suffers from a variety of network attacks, including the most typical one called wiretapping attack.This paper proposes a secure network coding scheme against wiretapping attack based on route selection.In the case that eavesdropped link position (unreliable link position) is known, we analyse the messages transmitted by eavesdropped links.Under the premise of ensuring the maximum network flow, we try to remove less eavesdropped links or normal links to ensure that the eavesdropper cannot get complete network source information while the destination node can normally receive all the information.According to the obtained topological structure of secure network, we construct new system transfer matrix and get the secure network code, so as to achieve the purpose of resisting wiretapping attack.Simulation results show that the proposed scheme can effectively resist wiretapping attack.关键词
