The paper, “Misreporting Attacks against Load Balancers in Software-Defined Networking,” which was just accepted for publication in Mobile Networks and Applications, is the journal version of our previous paper in SecureComm’20 that quantified for the first time the strategy and impact of a compromised/malicious switch intentionally misreporting loads to a load balancing application on the […]

Coreset work receives DAIS Awards
Our work on coreset, particularly “robust coreset construction”, was recognized at the close-out of DAIS-ITA through two awards in the categories of “Military Impact” and “Commercial Prosperity”. See DAIS Awards.
Paper on “Flow Table Security” accepted to TON
The paper, “Flow Table Security in SDN: Adversarial Reconnaissance and Intelligent Attacks“, talks about how a host-based adversary can use the difference in packet delays to infer flow table state and policy, and then use the inferred information to design efficient DoS attacks. Its conference version was presented at INFOCOM’20.
Our proposal on “Inference and Control in Overlay Networks” got funded by NSF
The proposal, “Collaborative Research: CNS Core: Medium: Inference and Control in Overlay Networks”, proposes a joint project with Prof. Eytan Modiano at MIT to study the fundamental challenges and algorithms for observing and controlling a non-cooperative underlay network from the perspective of an overlay system. The Penn State team will lead the inference effort using […]
Hanlin passed his defense
Hanlin Lu worked primarily on data reduction techniques for reducing communication cost in distributed machine learning, with focus on coreset. Congratulations, Dr. Lu!
Paper on “adaptive FL” wins the 2021 IEEE Communications Society Leonard G. Abraham Prize
The paper, “Adaptive Federated Learning in Resource Constrained Edge Computing Systems,” published in IEEE Journal on Selected Areas in Communications, vol. 37, no. 6, pp. 1205-1221, Jun. 2019, is one of the first papers to rigorously study the optimization of federated learning tasks in the wireless edge network environment. Congrats to the whole team!
Paper on a better cascading failure model (CAMPR project) accepted to TPWRS
The paper, “Inclusion of Pre-Existing Undervoltage Load Shedding Schemes in AC-QSS Cascading Failure Models“, talks about improving the accuracy of AC-QSS based models of cascading failures in power grid by incorporating the effects of a built-in protection scheme (undervoltage load shedding) that will be activated in a distributed and autonomous manner during cascading. Congrats to […]
Paper on CAMPR project accepted to ICCCN’21
The paper, Budget-Constrained Reinforcement of SCADA for Cascade Mitigation, examines the problem of communication network design for monitoring and controlling a coupled power grid from the perspective of budgeted allocation of non-PLCC links. Congratulations to Vaji!
Paper on “Queuing Network Topology Inference” accepted to IFIP Networking’21
This work, Queuing Network Topology Inference Using Passive Measurements, studies for the first time the topology inference problem based on possibly uncorrelated end-to-end delay measurements originating from a single source. Compared to existing works using various kinds of active probing mechanisms, we take a very different approach of inferring the detailed queuing dynamics inside the […]
Paper on “attack against network tomography” accepted to TNSE
The paper, Stealthy DGoS Attack against Network Tomography: The Role of Active Measurements, extends our previous works on DGoS Attack by incorporating a defense mechanism through the design of measurement paths to mitigate the performance impact of stealthy attacks. This is the first work on defense against data manipulation attacks on network tomography, which has […]
