ETSI Technical Committee TCCE has finalized new algorithms in specifications ETSI TS 100 392-7 and ETSI TS 100 396-6 to secure TETRA networks against future threats, including quantum computer attacks, for at least the next two decades. Developed in collaboration with the ETSI quantum safe cryptography group and supported by TCCA, these updates introduce over-the-air key management and authentication mechanisms designed to withstand brute force attacks beyond 2040. The enhanced standard ensures continued high-level voice encryption and resilience for critical public safety, military, and transportation applications that rely on TETRA’s peer-to-peer capabilities and TDMA architecture. This upgrade reinforces TETRA’s role as a mission-critical communication technology capable of protecting sensitive government and emergency services against evolving cyber threats.
