Abstract: The invention relates to a remote-controlled system comprising: —at least one ground interface (3), from which an operator can control a remote-controlled vehicle; —at least one mission unit (7, 8) in said vehicle; and —a data link between said interface (3) and said mission unit (7, 8). Said system is characterized in that it comprises, on the ground and in the vehicle, security monitoring systems (6, 10) suitable for approving and/or authenticating critical data and/or commands exchanged between the ground and the vehicle and also suitable for verifying the integrity of said data. It is thus possible to use, on the ground as on board the vehicle, interfaces and units with a low level of criticality at the same time as interfaces and units with the highest level of criticality.
