Abstract:
The invention relates to a telecommunication system including a plurality of terminals divided into groups such that within each group each terminal can send multidestination messages to the other members of the group. Each terminal of a group is associated with encryption and decryption means so that each terminal can send multidestination messages that can be decrypted only by the other terminals of the group. The system includes a central server for distributing to each encryption and decryption means keys for secure transmission of communications within each group.
