The AIS (Automatic Identification System) is a system of communication between vessels, for example fishing vessels, which makes it possible to limit collisions between these vessels and which allows surveillance of the maritime traffic in view of the coast by virtue of coastal stations which listen to the communications. The collecting of these data by satellite allows maritime surveillance far from coasts and verification of the data transmitted by analysis of the signal received. The maritime surveillance authorities are desirous that the data, collected by satellite, relating for example to the position of the vessels in their territorial waters not be broadcast globally. Indeed, this would allow a user, by listening to the satellite, to ascertain the AIS messages exchanged far from these coasts. The AIS messages contain the position of the transmitting vessel, as well as its identifier, its direction, etc. The invention consists in implementing an encryption of the data that have been sent back down, based on the content of these data. The encryption of the data also allows the authorities to provide the AIS data as a service, possibly a pay-for service.
L'AIS (Automatic Identification System) est un système de communication entre navires, par exemple des navires de pêche, qui permet de limiter les collisions entre ces navires et qui permet une surveillance du trafic maritime en vue des côtes grâce à des stations côtières qui écoutent les communications. La collecte par satellite de ces données permet une surveillance maritime loin des côtes et une vérification des données transmises par l'analyse du signal reçu. Les autorités de surveillance maritime ne souhaitent pas que les données concernant par exemple la position des navires dans leurs eaux territoriales, collectées par satellite soient diffusées globalement. En effet, cela permettrait à un utilisateur, en écoutant le satellite de connaître les messages AIS échangés loin de ces côtes. Les messages AIS contiennent la position du navire émetteur, ainsi que son identifiant, sa direction,... L'invention consiste à mettre en place un chiffrement des données redescendues basé sur le contenu de ces données. Le chiffrement des données permet également aux autorités de fournir les données AIS comme un service, éventuellement payant.
