CA 2330534

The invention concerns a terminal com- prising a terminal module (1) and a personal se- curity device (31). The terminal (1) is adapted for receiving requests from an application (Fap) implanted on an electronic unit in the form of high level requests independent of the module (1) and of said personal security device (31). One at least of the terminal module (1) and the personal security device (31) comprises a reprogrammable storage memory and means for executing a filter software (F) translating the high level requests into at least one of (i) at least one data exchange sequence between the terminal module (1) and the user or (ii) at least an elementary command or sequence of commands executable by the per- sonal security device, and means for protecting said filter software (F, 62) to prevent any modifi- cation of said software by a non-authorised per- son. The filter software comprises means for identifying and/or authenticating the origin of requests transmitted by said application (Fap) implanted in said unit.

Ce terminal comprend un module terminal (1) et un dispositif personnel de sécurité (31). Le terminal (1) est adapté pour recevoir des requêtes d'une application (Fap) implantée sur une unité électronique sous la forme de requêtes de haut niveau indépendants du module (1) et dudit dispositif personnel de sécurité (31). L'un au moins du module terminal (1) et du dispositif personnel de sécurité (31) comprend une mémoire reprogrammable de stockage et des moyens d'exécution d'un logiciel filtre (F) traduisant les requêtes de haut niveau en au moins l'une de (i) au moins une séquence d'échange de données entre le module terminal (1) et l'utilisateur ou (ii) au moins une commande élémentaire ou une séquence de commandes élémentaires exécutables par le dispositif personnel de sécurité, ainsi que des moyens de protection dudit logiciel filtre (F, 62), pour empêcher toute modification dudit logiciel par une personne non autorisée. Le logiciel filtre comprend des moyens d'identification et/ou d'authentification de l'origine des requêtes émises par ladite application (Fap) implantée dans ladite unité.
