Together with her colleagues, Sophie Rain introduced a framework for adapting computer science content and delivery methods to a younger audience at the 16th International Conference on Informatics in Schools (ISSEP 2023). The reshaping of unplugged computer science activities is grounded in a meticulous analysis of experiences from sessions involving 192 primary school children, aiming to align with their developmental needs and capabilities. The TUW team regards the creation of an educational playground for primary and secondary school classes as a valuable contribution to the broader societal mission of fostering interest in STEM among more children, ensuring that our technological future is as diverse as possible.

2023-06-26  Achievement

The research paper titled “Glimpse: On-Demand PoW Light Client with Constant-Size Storage for DeFi” by Giulia Scaffino, Lukas Aumayr, Zeta Avarikioti, and Matteo Maffei has been accepted at the prestigious “USENIX Security Symposium” (August 2023). The paper introduces the “Glimpse” protocol, which enables secure cross-chain token transfers in a fully decentralized manner, eliminating the need for large commercial crypto-depots. One notable feature of the Glimpse protocol is its compatibility with blockchains that have limited scripting languages. The authors provide a specific implementation of Glimpse for the Liquid Network, which is a pegged sidechain of Bitcoin. The protocol’s security is proven within the Universal Composability (UC) framework, indicating a strong level of confidence in its security guarantees. The researchers also conducted an economic analysis of the Glimpse protocol. The cost evaluation reveals that verifying a simple transaction on Bitcoin-like chains using Glimpse incurs a maximum of 700 bytes of on-chain overhead, resulting in a one-time fee of $3. This fee is only twice as much as a standard Bitcoin transaction, demonstrating the efficiency of Glimpse in terms of transaction costs. Overall, the advancements presented in the paper open up exciting new possibilities for the world of cryptocurrencies.

During the Tuesday Lounge event titled “TU und Schule: Faszination Technik?” Sophie Rain introduced the “Abenteuer Informatik für Volksschulen” project (Adventure Computer Science for Elementary Schools), which started in May 2023. This initiative aims to cultivate interest in STEM subjects among children by showcasing the captivating nature of computer science. The project plans to organize over 20 workshops annually, specifically designed for third-grade students in Vienna’s elementary schools, providing an opportunity for 18,000 children to participate and engage in STEM activities. Laura Kovacs, the project’s leader, emphasizes the team’s primary goal of easing the transition for children from regular school activities to scientific research. While the role of universities in STEM education development is still evolving, we take pride in the contributions our students make towards this emerging trend.

2023-05-24  Presentation

SecInt PhD student Lorenzo Veronese delivered a talk titled “WebSpec: Towards Machine-Checked Analysis of Browser Security Mechanisms” at the 44th IEEE Symposium on Security and Privacy (IEEE S&P 2023). The talk presented a joint work with B. Farinier, P. Bernardo, M. Tempesta, M. Squarcina, and M. Maffei. It introduced WebSpec as the first formal security framework for analyzing browser security mechanisms. WebSpec enables both the automatic discovery of logical flaws and the development of machine-checked security proofs. When a violation is detected, the toolchain automatically generates executable tests corresponding to the identified attack trace, which are validated across major browsers. The effectiveness of WebSpec was demonstrated through practical examples, highlighting its versatility and broad range of applications.
