ABSTRACT:
Methods and apparatus are disclosed for a content encryption scheme using programmable hardware. In one embodiment, a content request is transmitted to a content provider. In response to the content request, a session key is received and programmable hardware is configured using the session key to produce a first configuration. An identification key is generated and the first configuration of the programmable hardware is used to encrypt the identification key. The encrypted identification key is transmitted to the content provider. Encrypted content containing the identification key is then received.
