We are a security research group in the NS unit, CNS division, at the Computer Science and Engineering department (joint between Chalmers University of Technology and University of Gothenburg). We also connect with researchers across units through the Chalmers Security & Privacy Lab.
We focus on attacks and defenses in networked systems, with emphasis on Internet routing, blockchain peer-to-peer networks, and distributed infrastructure. The lab is led by Dr. Muoi Tran. For recent updates, see our activity report (2025).
We’re excited to welcome Sarat today as a new WASP PhD student! Chalmers is already familiar territory for Sarat, who received his master’s degree here not too long ago. During his PhD, Sarat will work at the intersection of network security and distributed systems.
A very warm welcome to the lab, Sarat!
Our paper on studying the routing centralization and its impact on content censorship in IPFS has been accepted at the 28th International Symposium on Stabilization, Safety, and Security of Distributed Systems (SSS ‘26’).
We show that while IPFS promises censorship-resistant storage through decentralization, its content providers are largely exposed to routing attacks in practice. This potentially leads to large-scale censorship attacks, e.g., a single AS-level adversary hijacking roughly 100 IP prefixes can block more than 75% of all tested content from over 57% of requesters!
The full paper will be available soon.
Glad to share that we have two posters accepted at the upcoming ACM CCS 2026! They are about preliminary results on (1) measuring impacts of hardware contention on AI workloads and (2) evading the state of the art routing defenses. Congrats Weijia, Ilias, and Shahrooz!
We will be in The Hague this November, so reach out to us about those exciting research!
This week, we are incredibly happy to welcome Weijia and Shahrooz to Chalmers University of Technology.
Weijia completed her master’s thesis on federated learning security at the University of Manchester, and Shahrooz joins us after his PhD at the University of Massachusetts Amherst and research tenure at Cisco.
They will be working on exciting research challenges at the intersection of network security and AI. Looking forward to the collaboration ahead as we build the next chapter together!
Today, Shubham begins his PhD journey in our lab, working on network security for AI. Shubham recently earned his master’s degree at Chalmers, where he wrote his thesis with AI Sweden and published work on decentralized federated learning. We are thrilled to welcome him — this time as a PhD student!
