Method for communication between a user station and a network, in particular internet, and implementing architecture

摘要

The method is designed for communication between a terminal (1) fitted with a chip card reader (3) and a data transmission network (RI) e.g., an Internet The terminal has a first network (RI) access protocol layer including a determined number of logic communication layers (C1 - C4). The chip card reader (3) and the chip card comprise the second and third protocol layers, each including at least communication logic layers (CC2 - CC1, CCa2 - CCa1), called 'low' so as to permit data exchange between the chip card and the terminal (1). The method includes: - a first preliminary stage which consists of implanting, into the chip card (2a) a first piece of specific logic (23a) forming an interface between the 'low' layers (CCa2, CCa1) of the third protocol layer and with at least an application (26a) recorded on the chip card (2a); - a second preliminary stage which implants in the terminal (1), a second specific logic (13) forming interface with the 'low' layers (CC2, CC1) of the second protocol layer and with determined layers of the first protocol layer (C-2,C3). The first and second specific logic parts (13, 23a) include at least a matched pair of first logical entities.(132, 232a), co-operating with each other so as to permit the establishment of a bi-directional data exchange session between the terminal (1) and the chip card (2a) and/or the network (RI).
