Abstract
A media server authenticates a user of a client device. The media server retrieves or generates a shared key stored at the media server, encrypts the shared key with a hash based on web session attributes of the client device. The server provides the encrypted private key to the client device after authentication of the user. The media server provides encrypted media content to the client device in response to a request from the client device. The client device decrypts the shared key and decrypts the encrypted media content with the decrypted private key.
