Abstract:
A method and system are provided for resetting a password using a first device and a second device. The second device stores data encrypted using a content protection key, which itself is stored in encrypted form using the password, and is also stored in encrypted form using a key encryption key. The first device receives a public key from a second device. The first device uses the public key and a stored private key to generate a further public key. The further public key and a new password are sent to the second device. The second device uses the further public key to generate the key encryption key, which is then used to decrypt the encrypted content protection key. A new content encryption key is created, and encrypted using the new password.
