Title: Ulrich Rührmair and Physical Unclonable Function Monitoring.
Introduction
Ulrich Rührmair is an inventor based in Frankfurt, Germany. His work includes a patent on monitoring a local environment using a physical unclonable function (PUF), a technique that uses the distinctive physical properties of a system to support identification and security.
Latest Patents
Rührmair is associated with 1 patent: “Monitoring of a Local Environment Using a Physical Unclonable Function.” The invention assesses a PUF by examining how a fixed local environment responds to electromagnetic challenge signals. It sends an initial challenge with predetermined parameters, uses data from the received signal to generate a modified challenge, and determines the channel impulse response from that modified signal. The resulting response is stored in association with the challenge, making the relationship between them less predictable.
Career Highlights
Rührmair is associated with IHP – Leibniz Institute for High Performance Microelectronics, a research institution focused on microelectronics. His patent reflects work at the intersection of electromagnetic signal processing, physical system characteristics, and security.
Collaborations
His listed coworker is Lara Wimmer. Their association provides context for the collaborative research connected with this invention.
Conclusion
Ulrich Rührmair’s patent describes a method for strengthening PUF-based monitoring by making challenge-response associations more unpredictable.
