Methods, devices, and systems are provided for managing and controlling small footprint devices with a lightweight control protocol, such as SNMP. Relatively small control messages are employed that have a compact command portion included in an object identifier portion, thereby circumventing the need for a separate command portion as well as a data body. Also, methods, devices, and systems for improving the security and privacy of processing SNMP messages on SNMP-managed devices by moving this processing together with the sensitive data that the process employ such a cryptographic keys inside the tamper-resistant and tamper-evident boundary of an integrated circuit card.

L'invention porte sur des procédés, des dispositifs et des systèmes de gestion et de commande de dispositifs à faible encombrement à l'aide d'un protocole de commande léger, tel que SNMP. Des messages de commande relativement petits sont employés qui comprennent une partie instruction compacte incluse dans une partie identifiant d'objet, pour ainsi se soustraire au besoin d'une partie instruction séparée ainsi qu'un corps de données. L'invention porte également sur des procédés, des dispositifs et des systèmes d'amélioration de la sécurité et de la confidentialité de traitement de messages SNMP sur des dispositifs gérés par SNMP par déplacement de ce traitement, conjointement avec les données sensibles que le traitement emploie telles que les clés cryptographiques, à l'intérieur de la frontière résistante aux infractions et indicatrice d'infractions d'une carte de circuit intégré.
