Security is the key for IoT and Industry 4.0. Many of the available security solutions for the Internet of Things scale poorly with the number of nodes, have too much latency or are not energy efficient. The maintenance, commissioning and handling of such solutions is also complex and static.
A promising approach is to improve security on the transmission layer in order to create security across technologies and frequencies for IoT and Industry 4.0 solutions. Wireless fading channels are a burden, but guarantee “perfect security” using information-theoretical results. Using the principle of the “physically uncloneable function”, such as a reciprocal wireless transmission channel, a unique, secure key that is tap-proof can be generated between two communication partners.
The “fast secure” research project aims to show that “physical layer security” concepts can also be implemented in reality on the transmission layer on hardware that is available today. This creates the basis for secure and fast communication for many sub-projects in the fast cluster and beyond.
