TETRA Security

Bachelor Thesis, Master Thesis, Diploma Thesis



We have a basic fuzzing framework for a digital trunked radio protocol, TETRA, which is used by public services. 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.


Depending on your knowledge, you can pick the following tasks and goals:

  • Implement an open source base station.
  • Implement an open source mobile station.
  • Implement a wireshark dissector for all fields.
  • Improve the fuzzing framework.
