Abstract

A method of controlling the use of an application. The application is capable of being executed on a portable object (SC. The method is characterized in that the method comprises the following steps:—a requesting step (REQ), in which a licence request is sent to a licensing remote server LRS;—a sending step (SEN), in which the licensing remote server (LRS) sends a token TK to the portable object (SC);—a validating step (VAL2), in which the token (TK) is checked so as to determine whether the token is valid or not; and—if the token (TK) is not valid, in an application-aborting step (ABO2), the execution of the application is aborted.

Claims

1. A method of controlling the use of an application capable of being run on a portable object (SC), comprising:

a requesting step (REQ), in which a licence request is sent to a licensing remote server (LRS);

a sending step (SEN), in which the licensing remote server (LRS) sends a token (TK) to the portable object (SC);

a validating step (VAL2), in which the token (TK) is checked so as to determine whether the token is valid or not; and

if the token (TK) is not valid, in an application-aborting step (ABO2), the running of the application is aborted.

2. The method according to claim 1, wherein the token (TK) is encrypted and wherein the portable object (SC) decrypts the token (TK) before checking the validity of the token (TK).

3. The method according to claim 1, wherein the requesting step (REQ) is preceded by a verifying step to check if the application is present on the portable object (SC);

and if not to cause the portable object (SC) to download the application from an application remote server (ARS).

4. The method according to claim 1, wherein the portable object (SC) is a SIM card SIC.
