BingoBoingo: So, in local bullshit it turns out the closed Zoo still has fucking animals https://www.elobservador.com.uy/nota/murio-clorinda-la-hipopotama-del-zoologico-de-villa-dolores-20181030115114
asciilifeform: btw, BingoBoingo , re waaay upstack -- trb 'throws bastards' from the simple reason that it doesn't keep track of peer heights, and ~always~ retransmits any block that it gets and happily welds to longchain
asciilifeform: ( i'm not actually certain why we do this test prior to bastardism, there's 0 point running any test on a block that fails do-we-have-its-father litmus . really this is leftover logic from removal of orphanage )
asciilifeform: tests for outrageous timestamps, sad pow, mutilated tx format
asciilifeform: aactually strike that, CheckBlock is called prior to bastardization litmus, http://btcbase.org/patches/asciilifeform_aggressive_pushgetblocks/tree/bitcoin/src/main.cpp#L1232
asciilifeform: more interestingly, there was even 1 of 10/30/18 17:05:41 ERROR: ProcessBlock() : CheckBlock FAILED from peer 213.148.193.153 ☟︎
asciilifeform: evidently there's a number of these.
a111: Logged on 2018-10-23 22:46 asciilifeform: i suspected shitfork, when realized that the 501 blox gotta be a few kB most, ea. -- my pipe couldn't disgorge 501 human-sized blox in <2sec
mircea_popescu: yeah ; and it'd better not be, the floor keeps crumbling underneath.
asciilifeform: ( and from there, whole chain )
asciilifeform: iirc you can trivially extract next-state of mt if you get 1
mircea_popescu: i suppose that could be the backup alternative then : if we end up ditching serpent, we use a rsa packet to move ~1.4kb of entropy for initializing the mt, and then use mt generated pads for a cipher.
diana_coman: for the udp tester
mircea_popescu: diana_coman did we end up with an ada impl of mersene twister at some juncture ?
mircea_popescu: as best i can tell -- the only options are either keep using serpent or else use some kind of recursive hash otp
diana_coman: and then I read the rest of the log; ofc
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: same observation arguably can be applied to errything else tho, so i'm not entirely sure it's a useful one.
asciilifeform: imho bitcoin is a quite poor cryptological 'mine canary' for this reason.
asciilifeform: for thread-completeness, asciilifeform will mention that he does not believe that ecc, as seen in bitcoin, is necessarily strong -- if there's a break, we won't hear of it unless somebody is catastrophically stupid -- it is analogous to those old safes that included 10 pounds of thermite for erry pound of benjie, torch it and you lose whole thing
asciilifeform: rsa & c-s (the latter, really a narrowed elgamal) are the only 2 oasis i know to exist in that desert.
asciilifeform: ( the 'intuitive' cure, 'let the primes be a sequence of primes, no prime used twice' is still breakable with fermat )
a111: Logged on 2018-10-30 16:53 asciilifeform: ( tho the reason why rsa is based on exponentiation, rather than straight multiplication-of-'plaintext'-prime-by-seekrit-prime is that in the latter variant you could trivially extract seekrit-prime with gcd )
asciilifeform: whereas if you don't throw them out, you have a reversible thing that is just multiplication, and i can gcd(p1,p2) == K.
asciilifeform: ( in the | 2^512 )
mircea_popescu: myeah. there's just no wai outs.
asciilifeform: you got a buncha intermediate addition bits that sink to the bottom of the sea
asciilifeform: it's the add-without-carry thing again
asciilifeform: mircea_popescu: multiplication with snipped off top half ?
asciilifeform: to make life even harder, rsa also suffers from 'can haz provably hard case' problem, there's classes of 'easy' primes, and no particular reason to think that we exhaustively know all of'em..
mircea_popescu: asciilifeform let's try something else. suppose key = 512 bit prime and suppose cipher works as E = P ^ K | 2^512.
asciilifeform: ditto prng. they're legs of triangle.
asciilifeform: sorta why it did not make sense to asciilifeform that people sat and 'i'ma make a hash', 'i'ma make a cipher', a good x is exactly a good y
asciilifeform: ( they're the same thing, if you had a provably working one, you get the other 2 gratis )
mircea_popescu: and that stands.
asciilifeform: in '16 we trivially reduced it to symmcipher == prng == hash
mircea_popescu: attempts to act "as if you had" will result in the above -- shredder.
asciilifeform: of course it is possible to come up with infinite variety of garbage ciphers that 'hey it confused me!' but imho not very useful activity
mircea_popescu: there will be no altcoin ; there will be no alt-cipher ; this is a jealous god we got here.
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
mircea_popescu: http://btcbase.org/log/2018-10-30#1867702 <<< very much this ; whereby it's actually the case we're starting to move towards an actual completion of the fucking field. ☝︎
asciilifeform: in '16 i burned coupla months on the q of 'can haz', mainly on np-hard problems / turing-complete cellular automata, in place of sboxation. but got stuck on the 'guaranteed hard instance' boojum.
asciilifeform: reasonable cipher requires element that is at least a ~conjectured~ trap door (i.e. 'entry is a buck but exit is two'), e.g. exponentiation-with-primes
mircea_popescu: and i further agree with you -- it is a very strong commentary and ceiling upon the security of "block ciphers". because yes, literally, all otehrs are just this with magic-numbered RBs. which... is EXACTLY the same "introduce say crc", except hidden under so much smoke.
mircea_popescu: asciilifeform i agree with you, this is a shredder not a cipher ; moreover -- if we for instance tried to add say crc into the message as padding, then therefore we'd be by the same hand introducing structure, ie weakness.
a111: Logged on 2018-10-29 20:56 asciilifeform: the basic boojum is that it aint a cipher of any kind, and the ubiquitous sbox derpery is simply squid ink to obscure this. maslennikov details how he pointed this out to 1980s kgb and got sacked.
asciilifeform: ( tho the reason why rsa is based on exponentiation, rather than straight multiplication-of-'plaintext'-prime-by-seekrit-prime is that in the latter variant you could trivially extract seekrit-prime with gcd ) ☟︎
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: they go to /dev/null, there is no way to get'em back deterministically.
asciilifeform: what you got, is egyptian mul, with thrown out carries.
mircea_popescu: asciilifeform fuck me, NOW i understand what you were on about yest --- E aren't THE RESULTS, but merely THE LAST BIT of a result. consequently, not actually eq system.
asciilifeform: ( spoiler, btw -- if you had normal addition, yer algo reduces to 'multiply P by K', it'd then be exactly my 'egyptian' multiplier )
asciilifeform: perchance i can provoke mircea_popescu into writing a proggy that deciphers ?
asciilifeform: the gaussian elimination thing would work if you had add (as in with carries) rather than xor
asciilifeform: i gotta admit that i still dun grasp how to decipher unambiguously into 1 single orig plaintext
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: SO GOOD YOU HAD TO SAY IT TWICE!

mircea_popescu: aaahahah, "Entrepreneur at its finest, Kelli Kelly, so good you had to say it twice. Aspiring to become a Motivational Speaker and Author. Fresh and unique with uplifting energy you will feel immediately entering her presence. Kelli has a different story and comes from a very different upbringing.

asciilifeform: main imho tech problem of our time, is that brekekekekex-amplifier is a penny while effective filter is a pound+.
mircea_popescu: imo technology brought decay, but hey.
mircea_popescu: just like in the 80s, that same "here i am" was http://trilema.com/2016/portrait-of-an-adult-woman/
mircea_popescu: in 2010s, this "here i am" is ^
mircea_popescu: i think it goes deeper than that. the fundamental, biology-based female strategy is "here i am".
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'
mircea_popescu: pardon the spam ; i bothered because honestly, this is paradigmatic. i dunno any pantsuits ACTUALLY exist ; but i know for sure there's millions of these rachel-hos.
asciilifeform: kinda how americanfootballists keep playing until their legs won't carry'em
mircea_popescu: I create and sell fetish porn on clips4sale, and i create funny sexy vids on YouTube and some HOT sexy teasers ON PORNHUB. I created my website [https://www.kelllikellly.com] I am very proud of my website, i own it as well and updates soon!! CHECK IT OUT, Do it cuz it’s actually awesome and I mean hello.... I made it. Soooo Im a YoungMILF, i am independent and live a happy life. If your wanting an in person session, message

asciilifeform: mircea_popescu: wtf is that
mircea_popescu: http://p.bvulpes.com/pastes/t2Mou/?raw=true << dude fucking webtard sites... who the fuck lives like this ?!
asciilifeform: ( some folx 'want contribute', but mysteriously can't be arsed to actually load open problem into head )
mircea_popescu: there's also that.
mircea_popescu: asciilifeform so, the above : dood "wants to contribute". this want leads him through the rest.
mircea_popescu: holy shit, check that out, i found one of these for once.
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: also a++ tautology, 'hey, y'say not killed or bought yet? clearly not succeed yet'
asciilifeform: mircea_popescu: recall poor old al schwartz's reply to s.nsa ? 'if you succeed you will be killed or bought'
mircea_popescu: not enough "money" in the imaginary world for THAT, bitches!

mircea_popescu: i've temporarily misplaced the discussion of "let's say what can be said", brb finding it.
asciilifeform: ( ftr i dun currently have the faintest notion re how to prove that keccak is injective )
asciilifeform: http://btcbase.org/log/2018-10-30#1867617 << this is lulzy indeed -- 'let's replace 1 hash where we dun have proof of injectivity with ~another~ where we dun even know where to start proving' ?! ☝︎
asciilifeform: hey i too supplied some high octane confusium with which to be confused!11
mircea_popescu: now if only i managed to get these right on the first pass, stop confusing the shit out of everyone...
asciilifeform: i'm quite reluctant to continue with the fpgaization thing unless i can get at the former.
asciilifeform: 2nd best, is that i find the pill.
asciilifeform: ideally what i'll find is a proof that there are exactly 2**256 528byte expansions .
asciilifeform: diana_coman: correct, i haven't found the item i was looking for, thus far
diana_coman: asciilifeform, so you set A to the constant so that it cancels out with that rather than "any A as long as (xor a d f h)=0"
asciilifeform: diana_coman, mircea_popescu : i'ma feed the thing into an algebratron later tonight
asciilifeform: the alternative is simply too lulzy to take seriously, just nao
