Abstract

L'invention concerne un procédé d'accès à un disque flash USB et un disque flash USB correspondant. Ledit procédé d'accès consiste à recevoir une instruction d'accès pour le disque flash USB (S11) ; à déterminer que l'adresse d'accès de l'instruction d'accès est une adresse spécifique du disque flash USB (S12) ; et à exécuter une instruction APDU associée à l'instruction d'accès ou à renvoyer des données d'une zone désignée, de manière à répondre à l'instruction d'accès (S13). Le procédé d'accès à un disque flash USB décrit peut améliorer la sécurité de lecture d'un disque flash USB et mettre en œuvre l'application personnalisée du disque flash USB.
