SYSTEM AND METHOD FOR REMOTE RESET OF PASSWORD AND ENCRYPTION KEY |
摘要 |
Data is secured on a device in communication with a remote location using a password and content protection key. The device stores data encrypted using a content protection key, which itself may be stored in encrypted form using the password and a key encryption key. The remote location receives a public key from the device. The remote location uses the public key and a stored private key to generate a further public key. The further public key is sent to the device. The device uses the further public key to generate a key encryption key, which is then used to decrypt the encrypted content protection key. A new content encryption key may then be created.
