UltraSec

UltraSec aims to design, model and demonstrate the basis for a secure technology for networking IoT devices based on UWB, which enables the cost-efficient construction and operation of a highly secure, flexible digital infrastructure. Based on channel measurements, Fraunhofer HHI characterizes the UWB radio environment using secrecy maps that identify spatial areas of particular attractiveness for potential eavesdroppers. An essential prerequisite for the inclusion of the secrecy maps in UWB networks is an investigation of the fundamental limits for secrecy in the finite block length regime. In addition, data-driven approaches to construct practical coding schemes for eavesdropping security will be developed and complemented by provable learning guarantees. Finally, a measurement environment is being set up that enables targeted characterization and simulation of jamming and attack scenarios. The goal is the practical integration of physical layer security into the design of UWB networks.
