Patent

CA 2329044

The invention relates to a method for activating one (A i) of the applications of an embedded system, particularly of a chip card (2a) connected to a terminal (1) equipped with a reader, by means of a "web" browser. The terminal (1) and the chip card (2.alpha.) each comprise, in addition to the conventional protocol layers (101-102) corresponding to the ISO 7816 standards, a specific layer (13, 23.alpha.). The latter comprises intelligent agents (132, 231.alpha.1) for establishing two-way data exchange sessions, enabling the chip card (2.alpha.) to offer a "web" server functionality. In addition, the chip card (2.alpha.) comprises intelligent agents (ATS 1-ATS n) called script translators that interact with the applications (A i-A n), making it possible to activate a selected application (A i) using conventional commands corresponding to the ISO 7816 standards. In a variant of embodiment, provisions are made for a dynamic updating of the chip card (2.alpha.). particularly from the browser. The invention also relates to the corresponding embedded system.

L'invention concerne un procédé d'activation d'une (A¿i?) des applications (A¿1?-A¿n?) d'un système embarqué, notamment d'une carte à puce (2a) connectée à un terminal (1), muni d'un lecteur, par l'intermédiaire d'un navigateur de type "WEB". Le terminal (1) et la carte à puce (2a) comprennent chacun, outre des couches protocolaires conventionnelles (101-102), répondant aux normes ISO 7816, une couche spécifique (13, 23a). Cette dernière comprend des agents intelligents (132, 232a¿1?) pour l'établissement de sessions d'échanges bidirectionnels de données, ce qui permet à la carte à puce (2a) de présenter une fonctionnalité de serveur "WEB". En outre, la carte à puce (2a) comprend des agents intelligents (ATS¿1?-ATS¿n?), dits traducteurs de scripts, interagissant avec les applications (A¿1?-A¿n?), ce qui permet d'activer une application sélectionnée (A¿i?), à l'aide d'ordres conventionnels, répondant aux normes ISO 7816. Dans une variante de réalisation, on prévoit des dispositions pour une mise à jour dynamique de la carte à puce (2a), notamment à partir du navigateur. L'invention concerne aussi le système embarqué correspondant.
