I am doing hdcp. I have a question about hdcpRngCipher implementation.
1 first AN value is generated by using random number seed.
2 other AN value is generated by hdcpBlockCipher sequence and mi,ki.
I want to ask which modules can work during hdcpRngCipher? if the operation mode is same hdcpBlockCipher, why last specification said that Rekey signal may but need not be enabled? (in fact hdcp BlockCipher need 56 clocks rekey enable.)
thanks!
