Abstract

L’invention a pour objet des systèmes de communication radio (100), des émetteurs radio (110) et des unités de supervision (150). Le principe général de l’invention est basé sur l’ajout d’une information d’identification aux signaux émis par les émetteurs d’un système de communication radio. Par ailleurs, les récepteurs du système de communication radio sont insensibles à l’information d’identification. En effet, on ajoute une unité de supervision au système de communication radio, qui est la seule à être sensible à l’information d’identification. C’est donc cette unité de supervision qui authentifie les signaux émis par les émetteurs. Fig.1The invention relates to radio communication systems (100), radio transmitters (110) and supervision units (150). The general principle of the invention is based on the addition of identification information to the signals emitted by the transmitters of a radio communication system. In addition, the receivers of the radio communication system are insensitive to identification information. In fact, a supervision unit is added to the radio communication system, which is the only one sensitive to identification information. It is therefore this supervision unit that authenticates the signals sent by the transmitters. Fig. 1
