This invention relates to a communication procedure between a terminal (1) equipped with a smart card reader (3) and data transmission network (RI), in particular of the Internet type. The terminal (1), the smart card reader (3) and the smart card (2a) comprise communication protocol layers (C1-C4, CC1-CC2, CCa1-- CCa2). According to the invention, the smart card (2a) and the terminal (1) each comprise an additional software layer (13, 23a) consisting of intelligent agents (132, 232a) in order to send all, or part of, the data flow via the smart card (2a). According to another characteristic, the smart card functions as a "WEB" server and supplies terminal (1) with an "HTML" page or a program that creates a virtual model. Intelligent agents (132, 232a) allow sessions to open between smart card (2a) and terminal (1). Additionally, this invention pertains to the system architecture for differential implementation of the procedure.

L'invention concerne un procédé de communication entre un terminal (1) muni d'un lecteur de carte à puce (3) et un réseau de transmission de données (RI, notamment de type Internet. Le terminal (1), le lecteur de carte à puce (3) et la carte à puce (2a) comprennent des couches de protocole de communication (C>1<-C>4<, CC>1<-CC>2<, CCa>1<-CCa>2<). Selon l'invention, la carte à puce (2a) et le terminal (1) comportent chacun une couche logicielle supplémentaire (13, 23a) comportant des agents intelligents (132, 232a), de manière à dériver tout ou partie du flot de données par la carte à puce (2a). Selon une autre caractéristique, la carte à puce joue le rôle de serveur "WEB" et présente au terminal (1) une page "HTML" ou un programme formant un modèle virtuel. Les agents intelligents (132, 232a) permettent l'établissement de sessions entre la carte à puce (2a) et le terminal (1). L'invention concerne également une architecture de mise en oeuvre du procédé selon plusieurs variantes de réalisation.
