asciilifeform: and certainly not for other, orthogonal (or even, possibly, contradictory!) properties such as non-leakage and non-structurization
asciilifeform: and the hashes popularly in use are optimized for strictly one thing -- (perceived!) collision resistance
asciilifeform: this is discussed publicly even less often than the pseudoscientific nonsense of block and stream ciphers, but: hashes are necessarily voodoo. elementarily, by counting argument (input:output sets are not 1:1).
asciilifeform: *flag into
asciilifeform: so here it is. flag.
asciilifeform: 'here -- mines.'
asciilifeform: y'know, sappers in popular imagination (and sometimes in life) actually clear mines, but just as often simply put little flat into the earth.
asciilifeform: (proved that there necessarily exists a hash boojum , for any given scheme that includes any hash of whatever kind, that makes the algo fall down.)
asciilifeform: in exactly the way i expected it would fall down on serious examination
asciilifeform: to briefly revisit earlier thread, i found an old piece by shoup that utterly demolishes the oaep nonsense. (unfortunately pdfized, and not convertible meaningfully.)
asciilifeform: see also, http://btcbase.org/log/2014-04-24#641281 . ☝︎
asciilifeform: догоним и перегоним! (tm) (r)
asciilifeform: mircea_popescu: the 'loc == revenue' is simply this century's version of chinese/su 'moar steel, revenue!'
asciilifeform: complexity -- is a cost. that it sometimes also brings something in return, is incidental.
asciilifeform: they are, to borrow from dijkstra, 'cost, not revenue, no matter how many people insist on writing them down on the wrong side of the ledger'
asciilifeform: (winblowz - wins!1!! forever!!1)
asciilifeform: rather like comparing 'lines of code'
asciilifeform: even then
asciilifeform: moar!
asciilifeform: or let's why not weigh james watt's steam engine vs modern diesel and say same thing.
asciilifeform: nobody thinks of weighing, e.g., 386 vs pentium to learn which one bangs moar for the buck
asciilifeform: mircea_popescu: we had thread about musculature of pan troglodytes, where many fewer cells in the muscle than a man's, but he can tear the man in half. so even for an ordinary mechanical 'strength', counting mass is nonsense.
asciilifeform: we already saw this movie before, with 'deep blue'
asciilifeform: so that it can look like 'ai'.
asciilifeform: gotta teach the 'grind student' again, by rote, the rote responses to the counterattacks actual people almost immediately came up with.
asciilifeform: *trotted out
asciilifeform: which, incidentally, i suspect is why alphago has not been trotted again.
asciilifeform: http://btcbase.org/log/2016-01-26#1386298 << oblig ☝︎
asciilifeform: well yes
asciilifeform: dusman!! i had nfi that this persian word, known to half the planet, made it as west as ro ☟︎
asciilifeform: usg has become such a loathesome and monstrous thing, that there is no fixed set of 'enemy', every earthworm in every step of ground it steps on, becomes enemy
asciilifeform: but the carrots begin to run out.
asciilifeform: afaik the structural diff is that usa traditionally relied on 'carrots' for the seekrit folx, more than 'sticks'
asciilifeform: (why not house'em in шарашкаs and be done with it, one might ask)
asciilifeform: quite likely there is an eight-figure golden toilet contract right at this very moment to attempt to roster, e.g., ts clearance holders who show symptoms of having used bitcoin. and the like.
asciilifeform: that is, automated probing for sudden curiosity, or evidence of ideological unreliability of whatever origin.
asciilifeform: the real megabux are, apparently, not even in 'data leakage prevention', as the earlier crackpottery is known, but in the yet (afaik) nameless ~detection of the turned~
asciilifeform: hence ethertardium etc.
asciilifeform: their ancient dream, yes.
asciilifeform: the mechanical politruk, which doesn't 'quis custodiet ipsos custodes?', and cannot be bribed, bought, needs 0 rest, can really 'plug into all of the telescreens at one time in the ministry of luvvvv', etc.
asciilifeform: dun like drinking piss? then stop being known for 'travail arabe' .
asciilifeform: this 'works' is a pestilence and is largely why clueful greybeards from the meat world , e.g., mircea_popescu , unzip and piss on programmers simply for sport ☟︎
asciilifeform: you really expect real time response, what are you , a martian' or, or, or
asciilifeform: http://btcbase.org/log/2016-12-24#1590218 << i cannot resist going back to this and giving it another whack of the spiked club. this variant definition of 'works', whereby things such as clim supposedly 'work', how would folks such as gabriel_laddel like if their cpu worked like this ? on and off, when weather is just right, and randomly melts on odd-numbered thursdays, and 'oh dontcha know you gotta jiggle the handle', and 'wtf did ☝︎
asciilifeform: every 'security software co' in usa wants in.
asciilifeform: it is like rerun of 1990s drm idiocy
asciilifeform: i dug up, last year, an inqtel-funded thing where... camera watches, it claims, for eyes of evil snowgnomes peeking at screen, etc.
asciilifeform: or whatever to call the nonsense where 'oh noez, mr.slave is flipping pages TOO FAST'
asciilifeform: or at the very least properly pwn the pnoje, it isn't as if this were especially arduous.
asciilifeform: http://btcbase.org/log/2016-12-24#1590209 << this sounds like a monumentally retarded idea. enemy will immediately see that you are flipping through the crapola, and 'snowden detection' is the fashionable 'must have!111' corporate idiocy. pull the NAND flash like a real man. ☝︎
asciilifeform: and that it is a mile of duct tape.
asciilifeform: how about that it isn't in the standard ?
asciilifeform: !!up gabriel_laddel_p
asciilifeform: (where did PeterL go... he might have something to say to this.)
asciilifeform: so generally you can make your custom whatever, out of standard parts.
asciilifeform: !!up gabriel_laddel
asciilifeform: whereas modern joints are quite reasonably tight
asciilifeform: i suspect that chemists of old days used a great bit more custom glass than today not only because borosilicate was not a thing (and so, easier to melt) but also because their ground joints sucked
asciilifeform: http://btcbase.org/log/2016-12-24#1590173 << how often do you need custom glass, gabriel_laddel ?? ☝︎
asciilifeform: http://btcbase.org/log/2016-12-24#1590185 << acetonitrile then ☝︎
asciilifeform not tried
asciilifeform: adlai has one ☟︎
asciilifeform: gabriel_laddel: how's the hardware biz?
asciilifeform: at least it wasn't COM-LAUNCH-ROCKETS..
asciilifeform: i.e. problem is really two problems.
asciilifeform: (it also has entirely separate component that is rivest's 'all or nothing transform')
asciilifeform: also betcha this problem could be reduced to shannon's noisy channel.
asciilifeform: aha
asciilifeform: it is an absolute fail for payload and padding to live in separate and known-to-enemy bitfields, yes
asciilifeform: (link -- loads, has a turd by same title and stock photos of 'collegiate' crapolade, i did not read further )
asciilifeform: http://btcbase.org/log/2016-12-24#1590098 << btw it is apparently back ☝︎
asciilifeform: (and not merely by the obvious lobotomist)
asciilifeform: i suspect that a good bit of crypto research was lobotomized by historic rng poverty.
asciilifeform: *was
asciilifeform: rivest wss afaik the first to ask for this. but he and afaik everybody since him, used hashes.
asciilifeform: gives NO knowledge of j.'
asciilifeform: of k rather
asciilifeform: all but one bit of j,
asciilifeform: informally stated , it is 'spread out k bits over j bits, j>k, such that the bitness of k that can be learned from knowing any 1 bit of j is minimized, and such that knowledge of a
asciilifeform: that was actually where i stopped last time. to properly and rigorously define the problem
asciilifeform: that is quantifiable
asciilifeform: there is a specific job involved
asciilifeform: i suspect that one could even prove that it cannot.
asciilifeform: and yes, the cost is high. but i remain unconvinced that a better method exists.
asciilifeform: but that was anally calculated. i have not tried with trng yet.
asciilifeform: http://btcbase.org/log/2016-12-24#1589914 << there ☝︎
asciilifeform: 3x was ~minimal inescapable bloat with no entropy~
asciilifeform: noooo
asciilifeform: i estimated a 16 fold margin.
asciilifeform: that, you do, i warned.
asciilifeform: you naturally gotta run long enough for p(walked all many times) to ~= 1
asciilifeform: http://btcbase.org/log/2016-12-24#1590091 << didja try it? and, importantly, was it with a physical trng?? because noshit , ~prng~ will structurize ... ☝︎
asciilifeform: http://btcbase.org/log/2016-12-24#1590078 << holy FUCK the ugly beast ☝︎
asciilifeform: i'ma bbl, off to play with pet.
asciilifeform: 'This has been a production of Rubbish From asciilifeform's Desk! No actual mathematicians were harmed...'
asciilifeform: seems like one could do a formal , sane proof.
asciilifeform: but i presently have nfi which one wins.
asciilifeform: 1d also eats full byte, puts 4 ops in it.
asciilifeform: you can generalize for n-dimensions, as mircea_popescu suggested earlier, similarly.
asciilifeform: say that the first bit of every tape pair means 'left or right', and the second 'flip or noflip.'
