Abstract
A method for exporting on a UICC in a terminal. An export request signed by the UICC, is transmitted by the terminal to a secure server. The server verifies the signed export request by comparing the signature and the identity of the UICC. The server sends a signed export certificate to the UICC via the terminal. An export package containing the data is prepared, signed and encrypted by the UICC, and sent to the terminal. The terminal transmits the export package to the server. The server signs an acknowledgment message and transmits it to the UICC via the terminal. In the UICC, the data that have been exported is destroyed, and a signed acknowledge message is sent to the server via the terminal. The server makes the data available for a further transfer to a new terminal or UICC.
