The Secura Lab is a research group in the Computer and Network Systems division at the Department of Computer Science and Engineering (CSE), which is joint between Chalmers University of Technology and University of Gothenburg (Sweden). We also have an organic connection with the Chalmers Security & Privacy Lab.
The Secura Lab is led by Dr. Muoi Tran. The primary goal of our lab is to enhance the security of computer systems, particularly those that are networked. Our research includes areas such as security in Internet routing, peer-to-peer security on blockchain, and the security of network infrastructures. Take a look at our publications page to learn more about our recent publication.
We are hiring PhD students! Check the job description via »this link«.

News
We are looking for enthusiastic candidates to join our newly launched lab as PhD students! These positions tentatively focus on network security problems in blockchains and AI/ML systems. That said, the research topics are quite flexible and so is the starting date. Note that the application deadline is 31 March, 2025.
All necessary information can be found in this link. We recommend a thorough read.
Please reach out to Muoi Tran if you have any further questions.
A new paper on fuzzing Proof-of-Work and Proof-of-Stake blockchain implementations has been accepted at IEEE/ACM ICSE 2025! This is a joint work with our collaborators from KAIST (Korea) and NUS (Singapore).
Blockchain systems run on top of P2P networks of nodes who collectively adhere to consensus algorithms. What may go wrong if nodes use different clients (or different versions of the same client)? Unsafe consensus! Tailored to detect discrepancies in how blockchain clients handle the complex fork resolutions, our fuzzing tool Forky found several unreported bugs in the most two popular blockchains, namely Bitcoin and Ethereum.
The full paper will be available soon.
Muoi Tran has been acknowledged as one of the top reviewers at ACM CCS ‘24. Thanks the program chairs! This honor is a testament to our lasting commitment to contributing high-quality reviews to the community.
Muoi will again serve on the technical program committee, and also, on the organizing committee as a Poster/Demo chair at ACM CCS ‘25’ in Taipei (Taiwan).
Along with Muoi Tran accepting the offer to join Chalmers University of Technology, we have a new lab.
Secura means secure in Latin. It is what we do – securing (networked) systems from lower layers and up!

Our paper on routing attacks against cryptocurrency mining pools has been accepted at IEEE S&P 2024.
We propose the Erosion attacks, in which network adversaries disrupt Proof-of-Work mining pools at scale. Check our paper to see how 96% of Bitcoin mining power can be disrupted by tampering with a few packets!
