HDCP uses two main phases of operation: authentication
and the link integrity check. The FC starts authentica-
tion by writing to the START_AUTHENTICATION bit in
the serializer. The serializer generates a 64-bit random
number. The host FC first reads the 64-bit random num-
ber from the serializer and writes it to the deserializer.
The FC then reads the serializer public key selection
vector (AKSV) and writes it to the deserializer. The FC
