Title
(EN) METHODS AND APPARATUS FOR PERFORMING SECURE BACK-UP AND RESTORE
Abstract
(EN)

Back-up procedures for saving configuration data are provided, which enable the restoration of said configuration data on the device when it is reset to default, or on another device when the device is stolen or broken. Since configuration data are sensitive data, it is important to protect their confidentiality and their integrity throughout the back-up and restore process. Current solutions enable a secure back-up and restore process on the same device since the backed-up configuration data are encrypted using credentials that are only known to the device. In order to overcome these drawbacks, a solution is proposed for performing a secure back-up process which enables the restoration of the backed-up data to the same device or to a distinct device. This is made possible by using encryption keys that are common to a pool of devices. Those common encryption keys are provided during the manufacturing of the devices.
