Current scientific projects


Prof. Gerold Hölzl is Project Coordinator of the Project TAKTICS for Digitalisation in Industry - Zentrum Digitalisierung.Bayern (ZD.B) at the University of Passau.

The goal of TAKTICS is to provide the necessary competencies to apply theoretical knowledge and methods in operational- and industrial practice. To achieve this, university lecture modules are created and/- or are adapted in teaching and positioned in the regular curriculum. This allows students to work on real and actual problems in detail. Students will get to know the specificities of the industrial context. The industry supports this project by providing professional and practical expertise as a mentor and the university provides the scientific and didactic professional as a coach.


Prof. Gerold Hölzl is German Coordinator of the Project NA2STY (Networked Appliances, Applications and Sensing Systems for the Smart City), DAAD GE-Seed 2016/2017, University of Passau and the German University in Cairo:

The Internet of Things assumes that objects have digital functionality and can be identified and tracked automatically. The combination of high-bandwidth connectivity, the availability of Internet-based services, and ubiquitous computing allows for communication, interaction, and information access everywhere and anytime to be embedded into anything.
Vehicles, devices, goods, and everyday objects become a part of the Internet of Things. The network of interconnected devices scales from the smart home to the smart city, including all infrastructures.
Challenges include the design, development and implementation of suitable protocols, middleware and services in the area of networking, computing and interaction.

Finished projects with head of the group Prof. Polian (untill october 2017)

Identification and Test of Vulnerable Components under Process Variationen

Founded by the German Research Council (DFG) within the second funding phase of the collaborative program Realtest.

Summary: Nanoelectronic circuits and systems are increasingly affected by massive statistical process variations. To guarantee stable operation, they most be designed robustly, i.e., equipped by fault protection mechanisms working at different levels. The project develops methods to analyze system vulnerability under process variations. One focus is identification of vulnerable system parts not covered by system-level fault handling. The analysis can support robustness enhancement. Furthermore, special automatic test pattern generation approaches taking a large number of constraints into account are developed based on SAT technology.

Trustworthy Manufacturing and Utilization of Secure Devices

EU supported COST action (IC 1204)

Hardware security is becoming increasingly important for many embedded systems applications ranging from small RFID tag to satellites orbiting the earth. Its relevance is expected to increase in the upcoming decades as secure applications such as public services, communication, control and healthcare will keep growing.  The vulnerability of hardware devices that implement cryptography functions (including smart cards) has become the Achille’s heel in the last decade. Therefore, the industry is recognizing the significance of hardware security to combat semiconductor device counterfeiting, theft of service and tampering. 

This COST action aims at creating a European network of competence and experts on all aspects of hardware security including design, manufacturing, testing, reliability, validation and utilization. The network will play a key role in developing solutions responding to the hardware security challenges, hence strengthening the position of Europe in the field.
