| 摘要 |
The invention relates to a method for high-speed data stream transmission to an Internet-type network (RI) between a remote server ( 4 ) and a smart card terminal ( 1 ). The terminal and the card each include a specific transmission protocol layer ( 13, 23 a). These layers include two intelligent agents (T<SUB>2</SUB>, T<SUB>1</SUB>, S<SUB>2</SUB>, S<SUB>1</SUB>), one being a server and the other being a client. The intelligent agents (T<SUB>2</SUB>, T<SUB>1</SUB>, S<SUB>2</SUB>, S<SUB>1</SUB>) enable the establishment of bidirectional data exchange sessions. The card then has the function of a client/web server. A filter ( 28 ) cooperates with the intelligent agents (T<SUB>2</SUB>, T<SUB>1</SUB>, S<SUB>2</SUB>, S<SUB>1</SUB>) to form a "proxy"-type function ( 27 ) implanted directly in the card. The data stream includes critical data that pass through the card and opaque data that pass directly to the terminal ( 1 ) under the control of the filter ( 28 ). Application in particular to multimedia data streams.
