Research Topics

  • Physically Unique Parameters for Authentication: We research on protocols that both authenticate a device and verify its physical parameters, such as location and timing. Compared to purely cryptographic methods, such approaches require lower computational capabilities of the devices while maintaining similar security guarantees. Our particular interest is in unique parameters that define the communication between devices. We aim to incorporate those parameters in low-complex authentication protocols.
  • 5G Localization based on Channel Impulse Response: The channel impulse response reflects the environment of the communicating devices. Direct line-of-sight communication links, reflections, scattered signals and interference can be found. For cellular communication we aim to extract the signal propagation time from the channel impulse response to estimate the range between devices. The advantage compared to time-of-arrival based ranging is the lower synchronization requirement of access points and less cooperation between mobile device and access point. Based on the range estimates, localization techniques are used to determine the location of the device.
