Title
(EN) METHODS AND APPARATUS FOR PERFORMING SECURE BACK-UP AND RESTORE
(ZH) 用于执行安全备份和恢复的方法和装置
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.

提供了用于保存配置数据的备份程序,这些备份程序使得能够在设备被重置为默认设置时在设备上恢复所述配置数据,或者在设备被盗或损坏时在另一设备上恢复所述配置数据。由于配置数据是敏感数据,因此,在整个备份和恢复过程中保护配置数据的机密性和完整性是重要的。目前的解决方案能在同一设备上实现安全的备份和恢复过程,这是因为备份的配置数据采用仅为该设备所知的凭证来进行加密。为了克服这些缺点,提出了一种用于执行安全备份过程的解决方案,该安全备份过程使得能够在相同的设备上或在不同的设备上恢复备份的数据。这通过采用设备池共用的加密密钥来实现。这些共用的加密密钥在设备的制造期间提供。
