ROV-GD: Improving the Measurement of ROV Deployment Using Graph Difference

BGP has been threatened by prefix hijacking attacks due to the lack of authentication mechanisms. In recent years, many ASes have begun to participate in RPKI deployment to improve Internet security jointly. Some researchers have studied how to measure the actual deployment of ROV globally, but such works suffer from the shortcomings of small measurement coverage and insufficient accuracy. Therefore, we propose RO-VGD, a ROV measurement method based on graph difference. We collect routing path data from the control plane and data plane. Then, we rely on prefix reachability and propagation edges for ROV inference. The results show that about half of the tested ASes have ROV filtering behaviors. In addition, our method can be extended to the ROV measurement of IXPs. Through validation and analysis, we prove that our method leads to convincing results and, at the same time, has a broader coverage and better applicability than other existing methods.
