<p>The method for a backup and restore of configuration data of an end-user device comprises the steps: encrypting the configuration data by using symmetric-key encryption with a symmetrical key, signing the encrypted configuration data with a device private key, and sending the encrypted and signed configuration data to a personal computer of a user of the end-user device, and/or to a storage location of a service provider network, for storage. For restoring of configuration data intended for use within the end-user device, a first or a second public key of an asymmetric key encryption system is used for validating signed configuration data provided by the service provider network or for validating signed configuration data stored on the personal computer of the user.</p> |
