Terrestrial Trunked Radio (TETRA); Security; Synchronization mechanism for end-to-end encryption
|Publication Date:||1 June 2003|
The present document defines the Terrestrial Trunked Radio system (TETRA) synchronization operation for end-to-end encryption algorithms that employ streaming ciphers for voice. The method defined applies equally to Direct Mode Operation (as defined in EN 300 396 (see bibliography)) and to Trunked Mode Operation (as defined in EN 300 392 (see bibliography)).
