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