PHYSEC is a spin-off of the Horst Görtz Institute for IT Security (HGI) in Bochum. The findings of Christian Zenger’s research and doctoral thesis at Professor Christof Paar’s Chair for Embedded Security were the motivation behind our successful application for the Federal Ministry for Economic Affairs’ EXIST Transfer of Research, and allowed us to develop our products on the basis of PHYSEC technology. The key idea behind our work is digital self-determination for our clients by applying digital business models that offer the highest levels of IT security whilst being simple to implement.

PHYSEC was established in early 2016 following a successful bid for the EXIST Transfer of Research. Based in Bochum, the management team consists of Dr Christian Zenger and Dr Heiko Koepke, supported by a team of five full-time and six part-time staff.

Products based on PHYSEC technology find application in the fields of critical infrastructures, home and building automation, and industry. The first customer projects were initiated soon after its foundation in 2016 and PHYSEC meanwhile boasts a growing customer base in these sectors. PHYSEC technology and the products and business models based on it have received many awards, including Bochum’s Senkrechtstarter (Highflyers), the Eco Internet Award – Next Generation Security, the international Security Rockstars competition, and in March 2017 it won first prize in the Federal Ministry for Economic Affairs’ Digital Innovation start-up competition, presented by Minister Brigitte Zypries.

PHYSEC also has a broad network of supporters from the research community and the political sphere. We are involved in diverse research projects working to optimize PHYSEC technology and are constantly on the lookout for new areas of application for our technology. Promising research areas for PHYSEC technology include the diversification of cryptographic keys, post-quantum resistance, protection from relay attacks and integrity protection.
