The present invention proposes a method for exporting on a secure server data comprised on a UlCC comprised in a terminal. The method consists in: On export request, signing an export request by the UlCC, the signed export request being transmitted by the terminal to the server; Verifying, at the level of the server, the signed export request by comparing the signature and the identity of the UlCC; If the verification is positive, sending by the server an signed export certificate to the UlCC via the terminal;Verifying the export certificate in the UlCC and, if positive, preparing an export package containing the data, the export package being signed and encrypted by the UlCC; Sending the export package to the terminal; and set the exported data as "unusable" in the UlCC; Transmitting from the terminal to the server the export package; Receive the package and verify the signature at the level of the server; Signing an acknowledgment message and transmit it to the UlCC via the terminal; In the UlCC, verifying the acknowledgment message and, if the signature of the server is recognized, destroying the data that have been exported and sending a signed acknowledge message to the server via the terminal; Verifying the signature of the acknowledge message in the server and, if the signature is recognized, making the data available for a further transfer to a new terminal or UlCC.
