SAFE INFORMATION INTERCHANGE BETWEEN A USER OF A TERMINAL AND A SIM APPLICATION TOOLKIT VIA WAP

摘要

A method and system for interchanging information safely between the user and a SIM Application Toolkit application in a telecommunication system comprising a terminal device (MS), connected to a telecommunication network (WN); a smart card (SC) inserted into the terminal device (MS); a WAP client program (WAPCLIENT) and a SIM Application Toolkit (STK), arranged in the terminal device (MS) and/or the smart card (SC); and a first application (WMLSCRIPT) which is part of the WAP client program (WAPCLIENT). The terminal device (MS) comprises the necessary features for using the WAP. As part of the WAP client program (WAPCLIENT), the second application (DRIVER) is added to start and control the SIM Application Toolkit applications. The first application (WMLSCRIPT) calls the second application (DRIVER) when wishing to use SIM Application Toolkit applications. The second application (DRIVER) controls and manages the SIM Application Toolkit applications and the interchange of information between the user of the terminal device (MS) and the SIM Application Toolkit applications.
