Title: TRANSMISSION OF DATA STREAMS BETWEEN A TERMINAL DEVICE AND A SECURITY MODULE
Abstract:
The invention relates to a method for transmitting data streams (20, 22) between a terminal (12) and a portable security module (10), which is provided with a web server, wherein the security module (1) receives a first request (26) that announces a processing data stream (20) and a second request (28) that contains the processing data stream (20). While receiving the processing data stream (20), the security module generates a result data stream (22) based on data of the processing data stream (20) that have already been received and transmits a first response (30) to the first request (26) during the generation of the result data stream (22), wherein the first response (30) contains the result data stream (22). Thus, more voluminous data streams (20, 22) can still be processed despite the limited capacity of the security module (10).
