Have you ever designed HDCP?
Can you give me some advice on how to generate Pseudorandom value An.
HDCP standard doesnt describe in detail.
thank you
 

Please visit following page ... it might help you

PN value can be generated by using a linear shift register with feedback and xor operation
 

Ask away - although im not on here much.

An is pseudo random 64 bit value so it can be anything. I use LFSR random number generator to do this.

It can also just be constant, or even 0.

Anything will do really!
