Firstly.. what is the diffrence between BISS and ConstantCW. Is the mechanism the same?
"CW" I think it means Control Word..
And what is the difference between ConstantCW and DCW(Direct CW?).
Why Control Words have 32b length, not 16?
And what is the reason for providers not to change CW, for some time(and DCW keys appear) ?
