DFG project NANOSEC – maximum IT security for tiny particles

The analogue world could make the Internet of Things more secure. In the DFG project NANOSEC, a research team in Passau is investigating future possibilities for the deployment of physically unclonable functions in memory structures and nanomaterial-based components.

In the analogue world, the way chips are produced causes unwanted, minimal deviations. But in fact, these unplanned variations make each chip unique in its own right. 'In computer science, we can take advantage of these differences because they enable us to identify hardware unambiguously', explains Professor Stefan Katzenbeisser, holder of the Chair of Computer Engineering at the University of Passau. These unique codes are known as physically unclonable functions, or PUFs for short. With the aid of PUFs, devices can be identified unambiguously, which means that the PUFs are rather like a digital fingerprint. At the present time, this is regarded as a robust and simple solution by means of which the Internet of Things, for example, can be made more secure.

In the DFG project "NANOSEC – manipulation-proof PUFs based on nanostructures for secure and robust hardware security primitives", the researchers in Passau have teamed up with the TU Chemnitz to combine their skills in the areas of hardware security (University of Passau) and nanomaterial-based components (TU Chemnitz). The tandem team are investigating the extent to which new semi-conductors based on carbon nanotubes are suitable for use in PUFs. Here, the team are developing and researching hybrid PUFs, which have both sensor and PUF functionalities. 'This could be a promising building block for security-relevant applications, for example in autonomous driving, because it delivers trustworthy, hardware-proof sensor data', explains Professor Katzenbeisser.

The German Research Foundation (DFG) is funding the project over a period of three years.
