6ME FW as a security engine provides the capability for setting up
7HDCP2.2 protocol negotiation between the Intel graphics device and
8an HDC2.2 sink.
9
10ME FW prepares HDCP2.2 negotiation parameters, signs and encrypts them
11according the HDCP 2.2 spec. The Intel graphics sends the created blob
12to the HDCP2.2 sink.
13
14Similarly, the HDCP2.2 sink's response is transferred to ME FW
15for decryption and verification.
16
17Once all the steps of HDCP2.2 negotiation are completed,
18upon request ME FW will configure the port as authenticated and supply
19the HDCP encryption keys to Intel graphics hardware.
