Process for allowing direct encrypted communication between two terminals of a mobile radio network and groupings of stations and terminals involved. Process for allowing direct encrypted communication in one hop or simply direct between two terminals of a mobile radio network via satellite(s) and/or GSM/DCS after one of them is called via a fixed mobile radio station (2) of a network. After a first phase executed in the normal manner a numbering key is simultaneously generated by the identification card (0) associated with the calling terminal (1) and by the command structure of the network for the encryption/decryption of the data transmitted by radio link between the said calling terminal and the station. The said numbering key is then stored in the memory of the station, for transmission to the called terminal (3), when a radio link is established between the said station and the said called terminal for the communication requested by the calling terminal, to allow encryption/decryption of the data exchanged between the called terminal and calling terminal.
Procédé destiné à permettre une communication cryptée, directe en un seul bond ou simplement directe, entre deux terminaux de réseau radiomobile par satellite(s) et/ou de type GSM/DCS, après appel de l'un d'eux par l'intermédiaire d'une station radiomobile fixe (2) d'un réseau. Après une première phase de cryptage, réalisée de manière habituelle, une clé de chiffrement est simultanément générée par la carte d'identification (0) associée au terminal appelant (1) et par la structure de commande du réseau pour le cryptage/décryptage des données transmises par liaison radio entre ce terminal appelant et la station. Cette clé de chiffrement est alors stockée dans une mémoire de la station, afin d'être transmise au terminal appelé (3), lors de l'établissement d'une liaison radio entre cette station et ce terminal appelé pour la communication demandée par le terminal appelant, en vue de permettre le cryptage/décryptage des données échangées entre terminaux appelé et appelant.
