I noticed peculiarities in the behaviour of the delta-delta-3 system for
entropy estimation in the random.c code./ When I hold right alt or control, I
get about 8 bits of entropy per repeat fro the /dev/random which is
overestimated. I think the real entropy is 0 bits because it is absolutely
deterministic when the interrupt comes. Am I right or is there any hidden
magic source of entropy in this case?
Right shift, left alt, ctrl and shift make 4 bits per repeat. Is greater
randomness being expected from the keys that return 8 bits?
When I have a server where n blobk read, keyboard and mouse events occur
(everything is cached within huge amount of semiconductor RAM), the /dev/random
depends solely on the network packets. These can be manipulated and their
leading edge precisely sniffed. I think here exists a severe risk of
compromise. Am I right?
