Embodiment Construction

[0032] Referring to the drawings, a first IC card is indicated by reference numeral 1, manufactured by a first manufacturer, and includes a first java card platform 2 with a java virtual machine.

[0033] The first java card platform 2 supports the operation of an applet 3 provided by the first manufacturer and downloaded into the first IC card in a conventional manner.

[0034] Without limiting the scope of the present invention, the applet 3 may be a java card applet 3 or a SIM toolkit applet 3, which is a specific applet for communicating with a mobile phone. In the following description, the term "applet" may be understood as a java card applet or a SIM toolkit applet.

[0035] The platform identification number Id1 stored in the storage section 4 of the first IC card 1 is associated with the first java card platform 2 . The platform identification number Id1 is protected since only the manufacturer who produced the IC card 1 knows the location of the storage section 4 . ...

Abstract

Method for controlling the execution of an applet (3) for an IC Card (1) comprising a java card platform (2), including: a phase for downloading the applet (3) inside the IC Card (1); a phase for executing the applet (3) through the java card platform (2); a phase for storing an identification platform number (Id1) inside a memory portion (4) of the IC Card (1). The phase for executing the applet(3) comprises a first step of detecting the identification platform number (Id1) in order to prosecute the phase for executing the applet (3) with or without restrictions, respectively if the identification platform number (Id1) is not or is detected by said step for detecting. The applet (3) is a java card applet (3) or a SIM toolkit applet (3).

Description

technical field [0001] The present invention relates to a method for controlling the operation of a small application program for an IC card including a java card platform, the method comprising the steps of downloading the small application program into the IC card and running the small application program through the JAVA card platform A step of. The invention also relates to an IC card including a java card platform and a small application program. Background technique [0002] As we all know, electronic devices usually include a platform for running programs. [0003] More precisely, an electronic device generally consists of a hardware platform including underlying elements such as circuits, storage areas, and processors, and a software platform including a series of service programs. [0004] The service program is used to support the operation of user programs. [0005] More precisely, the java platform is a software platform including a compiler and a running engi...
