A Novel Route Randomization Approach for Moving Target Defense

Route randomization is an important research focus for moving target defense which seeks to proactively and dynamically change the forwarding routes in the network. In this paper, the difficulties of implementing route randomization in traditional networks are analyzed. To solve these difficulties and achieve effective route randomization, a novel route randomization approach is proposed, which is implemented by adding a mapping layer between routers' physical interfaces and their corresponding logical addresses. The design ideas and the details of proposed approach are presented. The effectiveness and performance of proposed approach are verified and evaluated by corresponding experiments.
