| 摘要 |
The invention concerns a method for high data flow transmission on an Internet-type network (RI) between a remote server (4) and a smart card terminal (1). The terminal and smart card comprise each a specific transmission protocol layer (13, 23a). The latter include two intelligent agents (T2, T1, S2, S1), one server, the other client. The intelligent agents (T2, T1, S2, S1) enable two-way data exchange sessions to be established. The card exhibits in that case the functional capability of a WEB server/client. A filter (28) co-operates with the intelligent agents (T2, T1, S2, S1) to form a proxy-type function (27) directly implanted in the card. The data flow comprises critical data, passing through the card and so-called opaque data passing directly through the terminal (1), under the control of the filter (28). The invention is particularly applicable to multimedia data flow.
