The Applied Cyber Security group belongs to the Chair of Security and Theoretical Computer Science at the Institute of Computer Science at University of Tartu.
We perform highly practical research in the field of cyber security, evaluating the security of the technology solutions used in our everyday life. Our focus is especially directed towards solutions with significant public interest that are used in Estonia. This includes electronic identity (e.g., ID cards and Mobile-ID), digital signatures, internet voting and similar topics.
Our aim is to develop our competence to act as an independent authority evaluating the security assurance of technologies, products and services provided by the government, industry and other institutions. We collaborate with industry by reporting our findings under a responsible vulnerability disclosure process. We serve the public by making our research publicly available and sharing our knowledge through various teaching activities.

Teaching and supervisionOur group contributes to the development of new cyber security specialists and researchers by various teaching and supervision activities. Currently, we are responsible for teaching the following courses:
- Applied Cryptography (MTAT.07.017)
- Wireless Technologies and Security (LTAT.04.009)
- Web Application Security (LTAT.04.013)
HardwareWe have access to various hardware that can be provided to students for experiments and reserch assignments.
