  2. HDCP:
  3. =====
  4. ME FW as a security engine provides the capability for setting up
  5. HDCP2.2 protocol negotiation between the Intel graphics device and
  6. an HDC2.2 sink.
  7. ME FW prepares HDCP2.2 negotiation parameters, signs and encrypts them
  8. according the HDCP 2.2 spec. The Intel graphics sends the created blob
  9. to the HDCP2.2 sink.
  10. Similarly, the HDCP2.2 sink's response is transferred to ME FW
  11. for decryption and verification.
  12. Once all the steps of HDCP2.2 negotiation are completed,
  13. upon request ME FW will configure the port as authenticated and supply
  14. the HDCP encryption keys to Intel graphics hardware.
