TErrestrial Trunked RAdio (#TETRA) standard is used in radios worldwide. Security researchers have found multiple vulnerabilities in the underlying #cryptography and its implementation, including issues that allow for the decryption of traffic. Not all users of TETRA radios use the specific #encryption algorithim called #TEA1 but it is the standard approved for export to other countries. https://www.vice.com/en/article/4a3n3j/backdoor-in-police-radios-tetra-burst

Christian KalkhoffOha, offenbar ist das bei #bos #funk genutzte #tetra protokoll nicht so ganz sicher, was die Verschlüsselung angeht. Offenbar aber nur bei Einsatz des Verschlüsselungsstandard #TEA1. In Deutschland (und Europa) wird aber nach meinen Informationen mit #TEA2 ein anderer Standard verwendet. Trotzdem mal weiter beobachten, wo das noch hingeht.
BOS Funk wird von den Rettungsdiensten, aber z.B. auch bei der Bundeswehr eingestetzt.
Researchers Find 'Backdoor' in Encrypted Police and Military Radios - Slashdot
A group of cybersecurity researchers has uncovered what they believe is an intentional backdoor in encrypted radios used by police, military, and critical infrastructure entities around the world. The backdoor may have existed for decades, potentially exposing a wealth of sensitive information trans...
