Abstract

La présente invention concerne un procédé d'envoi d'un code exécutable à un module de sécurité connecté localement à un dispositif de réception, ce module de sécurité comportant un microcontrôleur et une mémoire, ladite mémoire comportant au moins une zone exécutable prévue pour contenir des instructions susceptibles d'être exécutées par ledit microcontrôleur et au moins une zone non exécutable dans laquelle le microcontrôleur ne peut pas exécuter les instructions, caractérisé en ce qu'il comporte les étapes de séparation du code exécutable en blocs; d'adjonction auxdits blocs, d'au moins un code de gestion du bloc de façon à former un bloc étendu; d'introduction du contenu d'un bloc étendu dans un message de type prévu pour être traité dans le dispositif de réception, de telle sorte que l'ensemble du code exécutable soit contenu dans une pluralité de messages; d'envoi d'un message au dispositif de réception, ce message contenant l'un des blocs étendu distinct du premier bloc étendu; de traitement dudit message de façon à en extraire le bloc étendu; de mémorisation dans la zone exécutable de la mémoire, du code exécutable et dudit au moins un code de gestion du bloc reçu; d'exécution d'au moins un code de gestion dudit bloc étendu, ce code de gestion ayant pour effet de transférer le contenu du bloc dans une zone non exécutable de la mémoire; de réitération des étapes précédentes jusqu'à ce que tous les blocs étendus aient été mémorisés dans la mémoire à l'exception du premier bloc; d'envoi d'un message contenant le premier bloc étendu au dispositif de réception; de traitement dudit message de façon à en extraire le bloc étendu et de mémorisation du code exécutable du bloc reçu, dans la zone exécutable de la mémoire. L'invention concerne également un procédé d'exécution de ce code.
