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