35th Chaos Communication Congress: PHYSEC presents details on the application of their technology
At the 35th annual conference of the Chaos Computer Club (35C3), the largest international hacker meeting in Europe, Christian Zenger, David Holin and Lars Steinschulte presented PHYSEC’s Enclosure-PUF technology.
This year’s Chaos Communication Congress attracted more than 16,000 visitors to the exhibition halls in Leipzig on three days. Under the motto “Refreshing Memories” it was the venue for important debates, lectures and workshops on technical and socio-political topics.
It was the first time that we gave insights into the PHYSEC technology. With Enclosure-PUF we presented an innovative technology that makes it possible to verify the authenticity, integrity and physical state of a physical object and to prove corresponding statements via digital channels.
In public environments, data extraction from or manipulation of computer systems is easy to perform as it requires only physical access. The aim of the talk was therefore to demonstrate exemplary tamper resistance by means of a (very inexpensive) self-built test bed in order to protect secret information without attack detection or data erasure circuit. The use of electromagnetic waves (or their propagation behaviour) enables the protection of individual small components to be extended to the entire periphery of a system. This in turn leads to the detection of manipulations so that suitable countermeasures can be taken in good time. The protection can be used flexibly with regard to size and application.
In 2018, we were awarded the German IT Security Prize of the Horst Görtz Foundation for the development of the Enclosure PUF.
