Patent

CA 2366556

The invention concerns a method for loading an applet in a smart card (2a), using two loading programmes, a so-called In-loader (IL), stored in the card, and Off-loader, respectively. The invention is characterised in that two specific communication protocol layers are provided, one in a terminal (1) hosting the card reader, the other in the card. Said layers include in particular intelligent agents enabling the card to provide a WEB client/server and a CGI gateway functional capability. The method comprises at least one step during which a HTTP request is sent to the card, to address a HTML page, a step which consists in retrieving parameterising data transported by a HTML form and a step which consists in executing a second loading programme (IL) using the CGI functional capability to load the applet.

L'invention concerne le chargement d'une "applet" dans une carte à puce (2a), à l'aide de deux programmes de chargement, dits "In-loader" (IL), stocké dans la carte, et "Off-loader" (OL), respectivement. Selon l'invention, on prévoit deux couches protocolaires de communication spécifiques, l'une dans un terminal (1) hébergeant le lecteur de la carte, l'autre dans la carte. Ces couches comprennent notamment des agents intelligents permettant à la carte d'offrir une fonctionnalité de client/serveur "WEB" et de passerelle "CGI". Le procédé comprend au moins une étape pendant laquelle une requête "HTTP" est envoyée à la carte, pour adresser une page "HTML", une étape de récupération de données de paramétrage véhiculées par un formulaire "HTML" et une étape d'exécution du second programme de chargement (IL), par mise en oeuvre de la fonctionnalité "CGI", pour charge l'"Applet".
