Yagoba GmbH was founded in April 2013 in Graz, Austria, by three former university colleagues. Beginning of 2023 Christoph Herbst joined the management team and Manfred dropped out of daily business. Since May 2013 we executed more than 90 projects to the full satisfaction of our customers. Our developments are regularly certified for electronic payment systems. We are known as reliable partner for highly efficient code that meets highest security and quality standards. Together with our clients we define the requirements, timelines, interfaces and functionality to work as reliable and independent partner.
Stefan’s position at Yagoba is CTO (Chief Technology Officer), leading the product development and implementation. He is our expert for secure and efficient implementation. If you require support for payment applets (contact and contact-less application on cards or NFC modules), Stefan is the guy you need. In case you have performance problems with your Java Card applet running on a specific controller, talk to him. Stefan studied computer science with an emphasis on security and digital hardware design. He worked as postdoc researcher at the University of Bristol in the team of Nigel Smart, and published around 50 articles about the design of security hardware, SCA analysis and protection, microprocessor architectures and similar topics in high-ranked scientific literature.
As CSO (Chief Science Officer) Thomas ensures that Yagoba stays ready for the future. Beside his activities together with our academic partners, he is responsible for development of our staff. Additionally he leads development of our test environment. As former patent consultant, he also covers all our innovation and IP topics. Thomas studied computer science ("Telematik") with an emphasis on IT-security and digital hardware design of SCA-resistant crypto circuits. His focus during his PhD and postdoc research were SCA-resistant logic styles. Thomas is co-author of the "DPA Book": Power Analysis Attacks - Revealing the Secrets of Smart Cards. After his academic career, Thomas worked as a patent engineer and IP consultant at Anwälte Burger & Partner.
Christoph's position at Yagoba is CAO (Chief Administrative Officer). In January 2023 he took over the responsibilities from Manfred Aigner. Christoph cares for CCC (customers, contracts, and coffee). Additionally, he is responsible for project management of key projects, as well as application for and management of funded research projects. Most importantly, he makes sure that staff, management and shareholders stay happy and motivated. Christoph studied computer science focusing on applied security. He has a long history in security architecture, certification, and evaluation of embedded secure systems.He gained his experience on vendor side as well as on evaluation lab side.
