HDCP:
|
|
=====
|
|
|
|
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.
