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. |
