Method for controlling the execution of an applet for an IC card
A method for controlling the execution of an applet for an IC Card including a java card platform, includes a phase for downloading the applet inside the IC Card, a phase for executing the applet through the java card platform and a phase for storing an identification platform number inside a memory portion of the IC Card. The phase for executing the applet has a first step for detecting the identification platform number to perform the phase for executing the applet with or without restrictions, respectively if the identification platform number is not or is detected by the step for detecting. The applet is a java card applet or a SIM toolkit applet.
1. A method for controlling execution of a first applet in a second IC Card comprising a second java card platform, with the first applet initially intended for execution on a first IC Card comprising a first java card platform, the method comprising:
downloading the first applet into the second IC Card, and at least one parameter being sent to the first applet during the download;
detecting an identification platform number that identifies the first java card platform, with the first java card platform being in a memory portion of the second IC Card; and
executing the first applet, through the second java card platform, when the at least one parameter is correct, and when the at least one parameter is not correct, then blocking execution of the first applet, with the at least one parameter specifying a restricted subset of services of the first applet to be provided.
2. A method according to claim 1 wherein the at least one parameter includes a number of times the first applet may be executed.
3. A method according to claim 1 wherein the first and second applet each comprises a java card applet.
4. A method according to claim 1 wherein the first and second applet each comprises a SIM toolkit applet.
5. An IC Card comprising:
an IC card substrate;
a memory on the IC card substrate to store,
a first applet initially intended for execution on a different IC Card comprising a first java card platform,
a second java card platform and a second applet, and
at least one parameter associated with the first applet and an identification number that identifies the first java card platform; and
a processor on the IC card substrate;
said processor to cooperate with the memory to execute the first applet when the at least one parameter is correct, and when the at least one parameter is not correct, then block execution of the first applet, with the at least one parameter specifying a restricted subset of services of the first applet to be provided.
6. An IC Card according to claim 5 wherein the first and second applet each comprises a java card applet.
7. An IC Card according to claim 5 wherein the first and second applet each comprises a SIM toolkit applet.
8. An IC according to claim 5 wherein the at least one parameter includes a number of times the first applet may be executed.
