Abstract
The present invention allows creation of a backup key for backing up an encryption key inside a source trusted chip, encrypting the encryption key with the backup key, exporting the encrypted encryption key from the source trusted chip and storing it in a storage device, encrypting the backup key for transmission to a trusted third party. If the encrypted encryption key needs to be restored inside a destination trusted chip, the backup key and the encryption key encrypted with the backup key are imported to the destination trusted chip, where the encrypted encryption key is decrypted with the backup key inside the destination trusted chip to obtain the encryption key of the source trusted chip.
