Introduction of the Research Group

Our research group covers the full field of automotive safety and cybersecurity and maintains strong links with the Hungarian automotive ecosystem, particularly key TIER1 suppliers. Through close industrial cooperation, we have access to state-of-the-art technologies and methods, especially in automotive cybersecurity.

A central focus of our work is the interaction between cybersecurity and system reliability. We develop integrated design and analysis methodologies that address both functional safety and cyber-safety requirements, supporting the development of resilient and secure automotive systems. In addition, we have strong expertise in accident reconstruction and forensic analysis, with particular emphasis on accidents involving highly automated vehicles, including reconstruction methods, dominant conflict types, and liability-related issues.

Our research is strongly driven by industrial needs and supported by strategic partnerships. Within the MASPOV project, conducted with Ukatemi Technologies, we developed methods and tools for assessing vehicle safety and cybersecurity characteristics. In collaboration with Microsec, we adapted public key infrastructure–based authentication solutions for automotive systems and demonstrated their applicability.

A key outcome of our work is an integrated testing methodology for vehicle-to-vehicle wireless communication addressing both safety and cybersecurity aspects; its patenting and industrial exploitation are currently underway. Our expertise is also regularly requested by industry partners for the analysis of serious vehicle failures and traffic accidents.

We actively involve BSc, MSc and PhD students in our research, enabling them to gain practical experience and identify areas of specialization. We also support talent recruitment through the Safety First! competition, which exposes students to real-world automotive safety and cybersecurity challenges beyond formal education.
