My assumption is that the other Unixes weren't looking at interrupt timing to begin with, i.e. they've always been as starved for entropy as Linux eventually became.Well, you know what they say about assumptions.Smart people will come around and help correct them? :)That being said, does VXWorks even *have* an OS provided strong random number generator?Don't know, don't care.Why not? It carries your data.
Routers should not need strong randomness, at least the way the 'net works now, to carry my data...
Windows has CryptGenRandom, which AFAIK doesn't block, and survives everything but VM suspend/restore.FreeBSD also doesn't block.May I ask what FreeBSD's entropy sources are?
It depends - device drivers can add entropy. It does include interrupt stuff, but not, by the looks of it, timing information, so I await the results of your experiments with interest (note, btw, I didn't have much to do with FreeBSD's /dev/random). _______________________________________________ Full-Disclosure - We believe in it.
