Method for provisioning an applet with credentials of a terminal application provided by an application server and corresponding OTA platform

A hardware security element having stored therein a computer program implemented in an applet, said computer program being configured to:

• receive, from a terminal application, a request to provision said applet with credentials;
• send a short messaging service (SMS) message containing an identifier of said applet to an over-the-air (OTA) platform
• receive, by said applet and from said OTA platform, a mobile station international subscriber directory number (MSISDN) that said OTA platform has determined from a header of said SMS message, and said credentials that said OTA platform has obtained from an application server for association with said MSISDN;
• and
• send, from said applet and to said terminal application, a message informing said terminal application that it has been provisioned with credentials of said terminal application.

A method implemented by an over-the-air (OTA) platform, said method comprising;

• based on a request for getting credentials for a terminal application present in a terminal, receiving, by said OTA platform and from an applet comprised in a security element of said terminal, a short messaging service (SMS) message containing an identifier of said applet;
• adding, by an SMS Center located in front of said OTA platform, a mobile station international subscriber directory number (MSISDN) of said security element in the header of said SMS;
• sending, by said OTA platform and to an application server, a request for said credentials;
• in response to the request for said credentials sent from said OTA platform to said application server, receiving, by said OTA platform and from said application server, said credentials to be associated with said MSISDN;
• and
• sending, by said OTA platform and to said applet, said credentials associated with said MSISDN.
