Tetra Security Analysis by Fuzzing

Master Thesis


Analysis: 10
Empiricism: 7
Implementation: 5
Literature Research: 2


We have a basic fuzzing framework for a digital trunked radio protocol. First tests showed that devices implementing this protocol have severe security issues, for example, freezing and rebooting devices with minor packet modifications is possible. Since this technology is used by emergency services and big companies, these security issues are very critical, and hence need to be revealed and fixed.

Your tasks:

  • Extend the fuzzing framework for more message types.
  • Do a structured analysis of multiple devices implementing the digital trunked radio protocol.
