Daniel’s work on “Stealthy DGoS Attack: DeGrading of Service under the Watch of Network Tomography” is accepted to IEEE/ACM Transactions on Networking. Congratulations to Daniel on your first journal paper with me! This is the extended version of our earlier INFOCOM’20 paper with the same title, discussing the optimal attack strategies and the maximum damage of a stealthy in-network attack on end-to-end communications under the monitoring of tomography-based bad link detection.
