asciilifeform: mircea_popescu: loox, at least superficially, like a ok prng (for tetris at least). but how didja get the idea that it's fit for cipher ?
asciilifeform: aactually strike that, CheckBlock is called prior to bastardization litmus, http://btcbase.org/patches/asciilifeform_aggressive_pushgetblocks/tree/bitcoin/src/main.cpp#L1232
diana_coman: mircea_popescu, yes
mircea_popescu: diana_coman did we end up with an ada impl of mersene twister at some juncture ?
diana_coman: mircea_popescu, we agree on the result but not on the formula, lol; your formula says e(2)=p(2) xor k(1)*p(1) xor k(2)*p(2) xor k(3)*p(3) xor k(4)*p(4) right?
asciilifeform: mircea_popescu: multiplication with snipped off top half ?
asciilifeform: it's the reason for asciilifeform's lulzsubmission to mircea_popescu's 'block contest'. it wasn't even joak, it was 'rsa is the only tool in that box that i have any reason to think actually worx'
a111: Logged on 2018-10-30 16:51 asciilifeform: the closest thing i can think of to a working variant of mircea_popescu's device, is where you keep the carries, and use primes... and we know it as.. rsa

asciilifeform: perchance i can provoke mircea_popescu into writing a proggy that deciphers ?
mircea_popescu: diana_coman E[2] = 1 (because P[2] = 1) xor 1 (because K[2] = 1 and RB2[2] = 1) xor 1 (because K[4] = 1 and RB4[4] = 1). thus E[2] = 1.
diana_coman: mircea_popescu, but uhm, isn't that precisely the example I give in the comment and which leads to the wrong value? this: but with the formula above it would be E(2)= P(2) xor 0*P(1) xor 1*P(2) xor 0*P(3) xor 1*P(4) = P(2) xor P(2) xor P(4) = 1 xor 1 xor 0 = 0 .
mircea_popescu: diana_coman answered.
asciilifeform: mircea_popescu: i suspect roughly same dynamic as old-style spam. i.e. 'i heard others are doin' it, there gotta be moneys in it, so i'ma buy a webcam and interactivefetish kit'
asciilifeform: mircea_popescu: wtf is that
asciilifeform: there's an imho moar pertinent mircea_popescu piece, where 'archaetypical kid made gift for mother, out of acorns and matchsticks' or how did it go
a111: Logged on 2017-04-15 17:27 mircea_popescu: given the list of all the things that have been said already (this is really a tree, but in his perspective it's flattened into a list by nulling out all the values associated with the string nodes), his choice is :
a111: Logged on 2015-02-16 06:45 mircea_popescu: read one police report of crime x, you've read half of them. read ten, you've (practically) read them all. clinical psychology is only interesting to the patently insane, as a practice. otherwise all the notes say endlessly the same five or six things. there just aren't that many things to say.
asciilifeform: mircea_popescu: recall poor old al schwartz's reply to s.nsa ? 'if you succeed you will be killed or bought'

a111: Logged on 2018-10-29 21:54 mircea_popescu: K = 0101, P = 1110. RB = (1110), (1101), (1011), (0111). E1 = 1 x 1 x 0 = 0 ; E2 = 1 x 1 x 1 = 1 ; E3 = 1 x 0 x 1 = 0 ; E4 = 0 x 1 x 1 = 0 ; E = 0100.
diana_coman: for anyone following along, I can confirm I got same as mircea_popescu here: http://btcbase.org/log/2018-10-29#1867338 ☝︎
asciilifeform: diana_coman: correct, i haven't found the item i was looking for, thus far
asciilifeform: diana_coman, mircea_popescu : i'ma feed the thing into an algebratron later tonight
asciilifeform: diana_coman: http://p.bvulpes.com/pastes/aZuZQ/?raw=true << example of term elimination. but tbf i'm still working from the hypothesis that i must be mistaken, somewhere, and all of the keybits are conserved, and could prove this somehow...
a111: Logged on 2018-10-21 21:23 mircea_popescu: http://btcbase.org/log/2018-10-20#1864445 << not so, was briefly dead but then adobe released a new set after 5+ years silence and it's catching back up.
diana_coman: mircea_popescu, the parallel is actually quite striking, yes; otherwise though, if there is ONE thing that living in several countries teaches one is that there is nothing "Romanian" , yes
mircea_popescu: diana_coman http://trilema.com/2016/btmsr-block-cipher-competition/#comment-126940 << for your lulz compartment. ☟︎
a111: Logged on 2018-10-30 05:15 BingoBoingo: mircea_popescu: I'll give lobbes 24 hours to confirm before submitting to assumed mapping
a111: Logged on 2018-10-29 22:56 diana_coman: basically I get http://btcbase.org/log/2018-10-29#1867091 BUT can't yet follow it to http://btcbase.org/log/2018-10-29#1867092 mainly because it seems to me that the effect of A is basically in fixing d,f,h (so that xor(a,d,f,h)=0); in short: wouldn't a change (of any number of bits) in a trigger (if imposing xor(a,d,f,h)=0 still) changes further in b-h so that the resulting key schedule is different? theoretically that would be the ration

BingoBoingo: Anyways, after spending more time here I went from seeing contrasts versus Argentines on landing, to similarities to Argentines during the time ben_vulpes was here, to now accepting the Uruguayos are weird and alien in a way that makes the Argentines look like hill billies
a111: Logged on 2018-10-01 16:30 mircea_popescu: ~then~, after that gets established, one can step down, add another, and so on. like a steps process, with continuity and everything.
mod6: iirc mircea_popescu said we could even have three chairs(?) might be mis-remembering that (may have to log-dig for that). I'd be happy to continue doing my role with a TRB focus, or I could step down officially and just keep doing TRB stuffs without the fancy title.
mircea_popescu: http://www.voxnovus.com/60x60/2003_International_Mix.htm#Aaron_Rogier << keks.
asciilifeform: and mircea_popescu saw calendar in egypt, ditto
BingoBoingo: In 2003 between my junior and senior years of highschool I wrote a piece of music that my computer compiled only for the faggot running the concert to butcher my short biography at the time. http://www.voxnovus.com/60x60/2003_International_Mix.htm

mod6: (noad running with mod6_excise_hash_truncation.vpatch + mod6_phexdigit_fix.vpatch (reground, not yet posted because keccak) + asciilifeform_whogaveblox.vpatch
asciilifeform: diana_coman: i'm baking a proggy that shits out sister keys, if it still dun make sense, you can wait till its birthed and try yourself.
asciilifeform: diana_coman: errywhere else, it appears strictly as a copy of w(0)
asciilifeform: diana_coman: look at the recurrence, term a appears directly only once, in w(0)
BingoBoingo: ^ asciilifeform mod6 mircea_popescu Please correct me if I have misunderstood anything
asciilifeform: mircea_popescu: if we can agree to walk the key in same direction, we get same answ
asciilifeform: mircea_popescu: your 1st 'lmao will have to redo' is correct.
asciilifeform: also, mircea_popescu: 1 x 1 x 0 aint 1
asciilifeform: mircea_popescu: that's the k in my example, neh
asciilifeform: mircea_popescu: it'd be resolvable if that's actually what you had. but in fact you dun have.
asciilifeform: mircea_popescu: if i encrypt message=2 with key=10, i get same 5 as if i encrypt message=2 with key=10
asciilifeform: mircea_popescu: what's RB ?
asciilifeform: ( and if mircea_popescu's point was that ~all~ present-day 'block ciphers' are reducible to some variant of it -- the point is made )
asciilifeform: mircea_popescu: seems to me that ~now~ you correctly defined... the http://btcbase.org/log/2018-10-29#1867192 cipher. ☝︎
asciilifeform: mircea_popescu: feel free to bake this by curing the little proggy pasted earlier
asciilifeform: diana_coman et al : http://p.bvulpes.com/pastes/kH2Av/?raw=true << proper.
asciilifeform: diana_coman et al : http://p.bvulpes.com/pastes/uX1BM/?raw=true << for convenience, the recurrence eqs rewritten 1) as sexpr 2) with the orig constant-xors included
a111: Logged on 2018-10-29 19:22 diana_coman: asciilifeform, that helps, thank you! I had to take break and I'm slow on this sort of things so it'll take a while until I get to say anything
asciilifeform: mircea_popescu: 'write-only memory'
asciilifeform: mircea_popescu: http://p.bvulpes.com/pastes/gWzx9/?raw=true , satisfy yerself that it dun reverse
asciilifeform: mircea_popescu: your offsetting rotates (as e.g. ram on z80) or truncates? ( when message is shifted beyond the buffer bound ) ?
asciilifeform: mircea_popescu: meanwhile plz be so kind as to say how to decipher.
asciilifeform: diana_coman: can substitute with search-and-replace
asciilifeform: diana_coman: http://p.bvulpes.com/pastes/94fgv/?raw=true << the raw emacs-sewed recurrence equations, if it helps
asciilifeform: diana_coman: i'm still boggled re the sheer wtf of it all.
asciilifeform: diana_coman: that's exactly what i remembered.
asciilifeform: btw i seem to recall that the original mircea_popescu & diana_coman thread where 'let's try serpent' turned up that the current 'paper' is not in fact the original, and the orig has evaporated. nao gotta wonder what was in it.
a111: Logged on 2018-10-26 17:05 mircea_popescu: yeah but suppose some bright kid walks into here one day with that item we all suspect is under a rock somewhere
asciilifeform: mircea_popescu: as i understand not; we're at http://btcbase.org/log/2018-10-26#1866454 . ☝︎
a111: Logged on 2018-10-26 17:04 mircea_popescu: in short, because this winding discussion risks overwhelming buffers, the salient points are a) that i'm not ready to go to war over serpent, it's a meh-maybe item ; b) that building our spearheads around items we're not willing to die for may be how the converse of http://btcbase.org/log-search?q=bitcoin+corrupts altogether.
a111: Logged on 2018-10-26 16:48 mircea_popescu: i am experimenting with serpent, and yes it's borne of that ancient discussion of ours, but i'm nowhere near-ready to bake it into "this is tmsr secure disk"
asciilifeform: mircea_popescu: cuz it ~is~
asciilifeform: mircea_popescu: yer xoring overlapped copies, remember
asciilifeform: mircea_popescu: what would mean 'equiprobable' ? they're a 1:1 mapping
a111: Logged on 2018-10-29 15:53 mircea_popescu: it is entropy* conserving, where entropy* is a special "entropy-colored-for-meaning", but this isn't useful.
asciilifeform: mircea_popescu: it dun even seem like we need exotica here
asciilifeform: mircea_popescu: if it has a random component, it aint reversible, how wouldja reverse it ? with time machine ?
asciilifeform: mircea_popescu: they're reversible !
asciilifeform: now we factor out the ... xor 16#9e3779b9# xor Unsigned_32(I), it's an injective operation (neither adds nor subtracts entropy) ;
asciilifeform: mircea_popescu: 1/3
asciilifeform: mircea_popescu: not only were you right, but i just about have a handle on deriving the factual key bitness of serpent..
mircea_popescu: Mocky_ yeah but i wanted to drive the point home.
asciilifeform: Mocky_: yea , calls for an actual proof..
asciilifeform: diana_coman: aha
asciilifeform: mebbe i'm thick and it's a trivial provable ? ( diana_coman ? mircea_popescu
asciilifeform: mircea_popescu: somewhat related observation: designers of blockciphers are fixated on 'what if known plaintext block', but it is not clear to me why this has to be a living problem when you can fill up 1/4 or 1/2 or whatever of block with rng
a111: Logged on 2018-10-29 00:44 mircea_popescu: anyway, the likely reason they don't publish scratchwork is that before republic, nobody had any fucking idea how to do intellectual work. q is a lot like asking "why would doctors not wash hands". because before someone told them to, they didn't, that's why.
asciilifeform: mircea_popescu: i looked over notes from the 1st time i read the thing, and had same reaction then ! but then, left with 'maybe i find why'. 3y later, not found why !
asciilifeform: mircea_popescu, diana_coman , el al -- what am i missing ?
asciilifeform: iirc diana_coman asked a similar q, but cant currently turn up the thrd
asciilifeform: for I in 0..131 loop W(I) := Rotate_Left(W(I-8) xor W(I-5) xor W(I-3) xor W(I-1) xor 16#9e3779b9# xor Unsigned_32(I), 11); end loop;
asciilifeform: mircea_popescu: i have a serious wtf re serpent, and neither the s.mg/classic ada, nor the orig paper, has helped me to make sense of it, and i'm suspecting that i'm thick... so here it is:
a111: Logged on 2018-04-10 03:06 mircea_popescu: eh. the quality of police work has so terribly degraded in the past half century, if anyone does ANY PLANNING AT ALL it's a murder that'll never get solved.
asciilifeform: mircea_popescu: they not simply 'say same thing', it's a form letter, not even rubber stamped but initial'd by some monkey
asciilifeform: mircea_popescu: a little tricky to ~boot~ from rsa dump, with bare hands, tho
asciilifeform: mircea_popescu: funnily enuff, dun even need to be kronprinz, you pay fiddibux or i fughet how much it was
asciilifeform: mircea_popescu: idea being that one could enter pw even with other folx ( in e.g. restaurant ) looking on.
asciilifeform: mircea_popescu: i considered it, yrs ago, but imho it has serious minuses in the field
asciilifeform: mircea_popescu: if it's for cipher keys -- imho terrible idea to have ~all~ the key bits as physical switched in parallel, third party has no biznis being able to see the key simply by getting a peek at a keyed box with eyes
