Abstract

Le problème selon l'invention consiste à permettre la commande d'opérations telles que le verrouillage et le déverrouillage d'une serrure de véhicule par l'intermédiaire d'un terminal mobile tel qu'un téléphone intelligent. La solution selon l'invention porte sur un système de commande de véhicule qui présente un serveur de commande (130) qui peut communiquer avec un terminal mobile (110) d'un utilisateur de véhicule par l'intermédiaire d'une connexion réseau (120), et un dispositif de commande (140) qui commande le fonctionnement du véhicule et qui est configuré au moyen de la carte de circuit imprimé d'une clé de commande à distance pour verrouiller et déverrouiller une serrure de véhicule. Le serveur de commande (130) chiffre des données de commande pour commander des opérations de véhicule au moyen de l'ID de véhicule et d'une clé privée associée à l'ID et envoie les données de commande chiffrées au terminal mobile. Le terminal mobile (110) transmet les données de commande chiffrées envoyées par une unité de communication sans fil au dispositif de commande (140) au moyen d'une communication sans fil à courte portée. Le dispositif de commande (140) déchiffre les données de commande chiffrées transmises par l'intermédiaire du terminal mobile (110), puis exécute l'instruction contenue dans les données de commande lorsque le mot de passe à usage unique (OTP) contenu dans les données de commande correspond au mot de passe à usage unique stocké et n'exécute pas l'instruction lorsque les mots de passe ne correspondent pas.
