Abstract

L'invention concerne un procédé de mise en correspondance de données de dispositif et de ressources de serveur dans un environnement IoT, et une passerelle l'appliquant. Selon un mode de réalisation de la présente invention, un procédé de mise en correspondance de ressources IoT comprend les étapes consistant à recevoir, par une passerelle, des données en provenance d'un dispositif; à convertir, par la passerelle, les données de dispositif reçues en données de ressource par référence à une table de mise en correspondance que la passerelle possède; et à transmettre, par la passerelle, les données de ressource converties à un serveur. Ainsi, même si des dispositifs formant un système IoT sont ajoutés ou modifiés, la sécurisation des ressources est possible par l'ajout ou la modification d'uniquement une table de mise en correspondance dans un serveur IoT, sans modification du logiciel (SW) de la passerelle, et ainsi le processus est rapide et pratique.
