: mircea_popescu: there is sometimes 1 or even 2 rs232 ports , but they go at -12v/+12v , and needs level shifter, which in turn oscillates, and potentially pollutes rng
: ( tho perhaps, a FG with only 1 rng
plugged in, could be a 'fuckgoat' )
: ave1: simulator won't give you much useful to work with re analogue rng
, considering that it relies on amplification of physical (johnson) noise
: I was reading through the fg design (doing experiments with circuit simulators to see how the RNG
might work etc). I'll just continue with the next step.
: conceivably rng
is separable, can simply be rs232 jack in which e.g. FG goes.
: am i going to have rng
? how small can it then be ? if not small, and rng
, why is it not using a proper terminal ?
: am i going to have no rng
in this wallet ? how make change address then ?
: ( why? because asciilifeform doesn't like to crypto in any form, even as toy, on boxes without rng
, and some of his trb dev machines at the time had none )
: esthlos: the one piece of iron which was catastrophically absent was rng
, and this was fixed
: likewise, with a popped unit it will be possible to take multi-GB samples of the onboard rng
, and examine this.
: interestingly, a major puzzler was 'how to rng
'. most folx used some trigonometric crapola; it ~worked..
: i got various things. problem is that i do not currently have a popped unit where i can see the effect of $manipulation on rng
(or any other part, aside from general 'it crashed')
: asciilifeform, how's the rng
work ? maybe a bit of electric field can set out 1s ?
: ( the 'rma unlock' 32byte turd, is simply rng
: mircea_popescu: a break of the rng
would also do the job. ( admittedly , tall order , but listed for completeness. )
: speaking of which, it's still an open q, what to do re rng
: ( the others being the z-whatevers, 2 of'em and i can't recall how they differed, the one with 'z-snark' and other other, with the magical rng
: the debian rng
bug is a good example of hosed RNGs, that's a fine place to start
: douchebag, 99% of criminals hacking companies are working for a criminal organisation calling itself "the united states govewrnment", and 99% of the time their hacks include some rng
: Logged on 2018-03-28 19:32 asciilifeform: funnily enuff, if working rng
were standard on pc, 128bits from it would give unique-gensym ( the supposed problem , according to the gcc nitwits, with mktemp , is collision ) without O(N) searching ( as in mkstemp) with probability ~1
: and by extension, for instance, rng
( witness the lack of excitement among heathens in re fg, for instance : 'expensive, and what exactly does this do that my intel doesn't')
: ( where you apply a magictransform to the whole rfc4880 turd, to get a lattice and get the privs; or at the very least, diddled rng
that gives e.g. 48 bits of possible keyspace, so nobody finds straight collision, but their asic can walk it, or the like.
: illustration, so to speak, of the connection b/w 'physical' entropy and the rng
: there is afaik no adult rng
on board ( in what, exactly, is there one ? ) but it has usb socket for FG; and the typical shit webcam for gurl-powered rng
: diana_coman, a package called sys-apps/rng
-tools has a thing called 'rngd'
: Logged on 2018-04-22 17:46 asciilifeform: d00d spends his days having 2way convos with his rng
: in otherwords, the kernel's built-in RNG
: since you mentioned rng
: what source of rng
does your system use in a typical configuration ?
: when the RNG
is backdoored, the ephemerals are compromised, but not necessarily the statics
: 1 caveat re 'brute force needs machine the size of 10^bignum universes running for 10^biggernum yrs' is that it presumes a flat keyspace. whereas if instead you can exclude large chunks ( because, e.g., winblowz rng
is known to never output'em , or some other likewise ) ...

: ideally would want also not merely 'all 0' and 'all 1' but rng
, and then to plot time vs hammingweight, and look for correlation
: The exact micro-chip carries a great impact if perhaps you will be a winner or perhaps a non-winner throughout texas holdem video. The method locations you within the fretting hand will be of value, even now, content material micro-chip commonly known as all of the RNG
(Occasional Total Traffic generator) which gives the necessary steps for a professional to manipulate the exact cunning participate in and even botch the possi
: technically it wants ~three~ ttys, one for normal i/o, one for eggogs, one for rng
: or a defective rng
. or hell knows just about every broken-but-running mechanism.
: Logged on 2018-01-19 02:22 mircea_popescu: asciilifeform no, he's evidently not useful. but he's not a logic gate, either. he's certainly not human. the fundamental identification/classification of "i will deliver result X through randomly chosen path each time" is... rng
. at least to my mind.
: you ~use it~ as a clock crystal. but what it is... well... it's actually a rng
: i meant in the sense where e.g. the clock crystal on the fg, is not itself an rng
. even tho it has jitter.
: asciilifeform no, he's evidently not useful. but he's not a logic gate, either. he's certainly not human. the fundamental identification/classification of "i will deliver result X through randomly chosen path each time" is... rng
. at least to my mind.☟
: not one that you'd want to use as an rng
, at any rate.
: if you like, rng
with clearly visible spectral peak.
: motl is not a meat rng
tho. d00d suffers from a clearly identifiable fixation, 'the west' (tm)(r) where there is a 'capitalism' (tm)(r)
: incidentally the 'pull out rng
'a', then 'b', then 'both', then...' test is a low-tech preventer of 'enemy intercepts parcel and reflashes the cpld to shit marsaglia prng'.
: alright, i will now proceed to "rng
" your lines. starting with above : 21ec922676d4145fbcbc4e1d05436e31ffc45b0b6b30c38f3397840a2111282640ab321b906a9d911af757a3a6b550e8fc9aaffc9089a1ca881d980f60617c9b
<< very basic specificity-of-diddling lemma. i.e. if i put today's trilema through it, it isn't as if it knows in advance that it ain't an analogue-rng
-board plugged in, and what to shit out in response to a trilema that ain't yet been written☝︎
is not a resonance magic pill, just a resonance de-debugable-izers.
: asciilifeform definitionally, if your rng
is any good, it will type out shakespeare every so often.
: mircea_popescu: almost definitionally, if yer rng
is any good, it won't be pumping any resonance anywhere
: mircea_popescu: plugging prng in the place of the rng
!= deterministic algo in the civilized sense
: good rng
in fact lubricates convergence in all kinds of sims
: in that case rng
. in fact this is almost definition of what trng is for.
: ^ boatload of funstuff concerning , e.g., rng
testing methodology; rigorous approach to stego; novel attacks on symmetriccipherolade; various other interesting ( and quite compact ) items.
: mircea_popescu: actually frag is very capricious item, 'good rng
' , 100+ yrs of credible reports of folx within 'guaranteed corpse' radius, surviving with minor injury
: much simpler than that : if your rng
is broken someone somewhere will exploit it.
: mircea_popescu: maybe at some point we auction prototype rng
( asciilifeform has a few , mircea_popescu also, and somebody else i think )
: (nothing in crypto is useful, either, which severely limits the rng
uptake apparently -- if your crypto dun work anyway what need is rng
item or somesuch)
: evidently nothing in crypto is useful without rng
; what's this to do with anything ?
: ( what's the use, incidentally, of a cramershouptron, without sane rng
: and instead sat around uselessly , and wasted time making and selling rng
in the meantime also, lol
: ( i for instance have some approximate notion of how many people have an actual rng
. the number is not large. )
: ( for n00bz : ~one~ failure of rng
leaks entire privkey, in dsa. )
: if server generates all keys, client dun need an rng
: diana_coman: now let's split 1 byte into ~four~, A,B,C,D. we take same transform and do it to X and Y in turn. in total, we've used 4 bytes from rng
device, to cut 1 byte into 4 otpfrags.
: diana_coman: lemme give specific example. start with splitting 1 byte. to split byte B into X and Y, you take byte R from rng
, and compute B xor R = X. then Y = R . X xor Y = B .
: ( your encipherment speed is limited to 1/S of your rng
's bit rate, where S is the splitness )
: to expand a K-bit (block and key, we'll assume, are each K-bit) voodoocipher to J bitness, xor split ( on rng
); having generated J / K independent keys; each incoming plaintext block of J bits, is cut into J / K blocks, and each enciphered with the corresponding key. decipher -- same.
for some reason unable to turn up the thread in the l0gz where we did the 'rng
design is not a technical problem , but a political problem' thing
: asciilifeform so what do i get from divide by 0 ? rng
: afaik even the shoddiest 1980s hash algo, produce ~perfect 'white noise'. hence the popularity of faux-rng
via hashwhitener etc.
: generally there are cheaper ways to make use of 'key' to chump rng
: "all you need to know is where the signature 1blocks come in the "rng
", as they will be preserved by binary mult, can be seen in modulus."
: kinda why faux rng
calibration is done on 1blocks in the first place.
: (on proper rng
. on bs prng / kochgpg etc, they don't.)
<- confirmed; I do NOT use any nextprime or other "rng
"-parts from gpg; current rsatron prototype simply grabs nbits from fg, flips the 2 top bits and 1 bottom bit as per previous discussion and then checks if result is prime; if prime then keep, otherwise discard and try again; no "add 2 until prime" or other such thing☝︎
: afaik the only remaining, and most obvious 'loss' is the one implicit in prime number theorem ( where , wat, ~10k possible rng
outputs correspond to same prime output )
: ( she is using my sanitized gpg bignum. but i did not preserve koch's faux-rng
atrocity ; so anything pertaining to entropy, is new )
