asciilifeform: lol
asciilifeform: BingoBoingo: thing was never usg.adopted, was 90% of its orig appeal
asciilifeform: 'oh posting intermediate calcs Would Be Wrong (tm), some scum could find out that we're fulla shit', or is there some other plausible hypothesis here..?
asciilifeform: motherfucking academitards.
asciilifeform: so then i go an' reread the paper, and whole thing is in this style. 'oh i picked the sboxes based on shuffling des's and rejecting the variants that keep bits in position toomuch' but where IS this scratch work posted?? apparently nowhere.. )
asciilifeform: what's the win from the not-really-hash 'key schedule' thing?
asciilifeform: *et al
asciilifeform: mircea_popescu, diana_coman , el al -- what am i missing ?
asciilifeform: *expander
asciilifeform: ( anyone who considers 528byte an excessive key, can use e.g. keccak as expanded, instead of the 1970s strange , neh )
asciilifeform: for that matter, why not let user give the full 528bytes (132 x 32b) of key material, why this whitening is hardwired in.
asciilifeform: iirc diana_coman asked a similar q, but cant currently turn up the thrd
asciilifeform: i still dun grasp why the fuck the author used this adhocism, with 1way propagation, rather than an actual hash (and 'because all other blockciphers did' is not an answer.. )
asciilifeform: so nm.
asciilifeform: ( was about to ask 'so does it actually use the other 4 32b words..' then it clicked )
asciilifeform: or hrm, nm, i'm thick, after all
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: observe, in the key scheduler,
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:
asciilifeform: BingoBoingo: i have difficulty picturing the derps actually ponying up the coin to cover the not-insignificant cost of housing their rezistenta prin cultura idjitmagnet. but whoknows.
asciilifeform: not for long, anyway
asciilifeform: i suspect that they can no longer afford the 'luxury' of pepsi.
asciilifeform: all that remains is for ibm to merge with microshit-oogle
asciilifeform: reminiscent of banks in the '08 times
asciilifeform: usg.dept-of-kompyooting unification chugging along, eh
asciilifeform wishes the derps a smooth trip into the http://btcbase.org/log/2017-12-22#1756992 rubbish bin ☝︎
asciilifeform: lol!
asciilifeform: ( on rare occasions -- in airplane just prior to take-off, it makes for convenient ad-hoc jail )
asciilifeform: the checkpoint queues are ~100% theatrical, when they want some d00d 'by name', typically pick him up at the check-in desk, long before he gets to the queue ☟︎
asciilifeform: or could go on, but there's too many of these and they aint particularly interesting to catalogue
asciilifeform: or, say, woman's purse, nobody ever searches, they poke inside with a ceremonial stick.
asciilifeform: there is, for instance, an Official cap on benjies, iirc 10k. but nobody ever counted'em in any usg airport i've been to, for so long as they fit in wallet
asciilifeform: ( unlike ye olde su, usg has a shortage of fancy rubber stamps , for some reason )
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: e.g. the outer seals of the trunks with the 1u's, were popped, and the pieces helpfully taped to a 'this crate inspected for the motherland' receipt inside ( inner seals intact, lol )
asciilifeform: 1 factor is that usa is mega-travel hub, so extensive derping with erry suitcase is impractical ( queue is slow enuff from the bush-era 'bright idea' of inspecting shoes ). reportedly in e.g. israel they try to do the 'copy erry disk' thing, there it is at least roughly practical in re traffic volume
asciilifeform: evidently
asciilifeform: 'wtf, where is the plutonium in this suitcase, all derp has is buncha 1u's'
asciilifeform: the concept of 'terror cell' that has 1-800 pnoje also, i suspect, throws the gears out of alignment. 'but where is the seekrit inner one, where they mix sarin', i expect, is the eternal itch.
asciilifeform: from what i can tell, their entire concept of 'terror suspect' is a hardcoded enumeration of largely accidental/stylistic features, e.g. 'bearded camel fucker', 'weev', 'loud activist'
asciilifeform: ( tho theoretically even these get occasional sonderbehandlung 'pour encourager les autres' )
asciilifeform: ( i was speaking of the lul where they give you a subscription that opens the no-customs door on the way back ~into~ reich )
asciilifeform: i can picture
asciilifeform subscribed, worx, to date, a+++
asciilifeform: mircea_popescu: funnily enuff, dun even need to be kronprinz, you pay fiddibux or i fughet how much it was
asciilifeform: ( speaking here of proverbial, rather than the actual one, for some reason the actual border has ~0 interest in asciilifeform's cargo , to date, was almost disappointing. . 100x moar poking' and prodding' in orcistans this far, for asciilifeform )
asciilifeform: 'sure look at this box' 'go ahead, feel free to anally insert this card'
asciilifeform: btw i'll add, nobody with half a brain would cross idjit ameri-border with device + card. 1 or the other at a time.
asciilifeform: hmm?
asciilifeform: e.g.
asciilifeform: specifically it, no. but, say, using in a room where windows without blackout tape , possible use case.
asciilifeform: mircea_popescu: idea being that one could enter pw even with other folx ( in e.g. restaurant ) looking on.
asciilifeform: ( usg's locks work this way, one of their few sane techs, 1980s vintage. thing starts each new char at random init value, too, so peeker dun see anyffin useful from the side )
asciilifeform: tbf in principle you dun need kbd, at minimum, only 1 char 'eye hole' and left/right/enter button set
asciilifeform: was how i pictured it.
asciilifeform: ( where 'normal' is ps/2 say )
asciilifeform: easily
asciilifeform: mircea_popescu: i considered it, yrs ago, but imho it has serious minuses in the field
asciilifeform: ( iirc the prescribed key-wipe mechanism was a brick of dynamite, and the crew decided it wanted to live a bit moar )
asciilifeform: it's why usg lost its precious keyz when bestkorea took famous ship 'pueblo'
asciilifeform: ( you also wanna be able to unkey a box at a second's notice, and that aint happening with parallel key-as-switches, either )
asciilifeform: *switches in
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
asciilifeform: actually scrach that, it's a terrible illustration. but i dun have a good one handy.
asciilifeform: ( the classic pdp-8, that is )
asciilifeform: on subj : https://archive.is/7ILm0 << notbad illustration of how pdp was booted.
asciilifeform: flipping massive grid with fingers is a bitch
asciilifeform: i'll point out that nobody ever booted from '32x8 block' tho, if you recall folx booted from 8 (or 9 or whatever your byte bitness) + 'forward' button, word-at-a-time
asciilifeform: archaetypical example, say, https://archive.is/0IRmv photo
asciilifeform: or are we talking spring-loaded thingies for reading punched card, or wat.
asciilifeform: mircea_popescu: what sorta switches are you thinking of ? if it's ye olde DIPs, nobody cancelled'em, they're maybe a dime for a block of 8, and look today exactly as you remember then from yer 286
asciilifeform bbl:meat
asciilifeform: in today's variation, 'hey i found a dead mermaid' 'um, this is a bloated dolphin carcass' '...'
asciilifeform: sorta like the usual 'hey i found nessie' 'wouldja like to borrow my diving gear and thermal cam?' 'mmm nessie is invisible to thermal cam and what's a diving mask' '...'
asciilifeform: it went to where all cheap psyops lulz go when they die.
asciilifeform: observe that the gag vanished without a trace.
asciilifeform: famous lulgem
asciilifeform: mircea_popescu: http://btcbase.org/log/2018-10-27#1866787 << for the record >> http://trilema.com/2013/badbios-aka-badlydonedamagecontrol/ ☝︎☟︎
asciilifeform: !!help
asciilifeform: |\n get yourself a key already and reg with deedbot
asciilifeform: i saw |\n's snippet and thought 'loox familiar' and sure enuff it was in that 2017 piece.
asciilifeform: mircea_popescu: needs diddled bios + the crown jewels of intel/amd, to diddle microcode (intel's is rsa'd, amd's simply obscure/undoc'd) , and if yer diddling bios can make much simpler trap. but yes, would work
asciilifeform: mircea_popescu: not meritless, but not a weapon, toy store water gun, is the idea.
asciilifeform: theoretically the trigger for the ~actual~ boobytrap in x86 cpu would look very similar, yes
asciilifeform: the given coad does nuffin on an off-the-shelf chip. it was an example meant to work with supplied microcode patch.
asciilifeform: |\n: if it was shown to you as 'omfg exploit!111', you've been duped.
asciilifeform: http://p.bvulpes.com/pastes/oFd2X/?raw=true << full text of the pdfturd, for the l0gz.
asciilifeform: evidently sumbody passed it off to |\n as an 0day
asciilifeform: there's no 0day here.
asciilifeform: nah, it's part of a 'if you could patch microcode, here's how you might trigger the bomb' stage magic demo.
asciilifeform: 'As explained in Section 7.2, we use ASM.JS code in Firefox 50 to trigger the implemented x86 div Trojan. It is shown in Listing 9.'
asciilifeform: rather than a wild thing.
asciilifeform: mircea_popescu: yes i recall very well. this one is genuine, tho, but one half of a rigged academi-demo, requires ~their~ microcode patch
asciilifeform: ( flip to last pg )
asciilifeform: mircea_popescu: piltdown man
asciilifeform: eh |\n it's a duck : apparent source is https://ecc2017.coreboot.org/uploads/talk/presentation/38/Microcode.pdf talk , and demands a pre-diddled, per the recipe, old amd k8/k10
asciilifeform: |\n: where'dja come across this, and for what chip is it alleged to work ?
asciilifeform: http://p.bvulpes.com/pastes/jb4Pz/?raw=true << for perma-l0gz.
asciilifeform: mircea_popescu: linked item alleges that if one divides 0xa1a2a3a4 by 0xb1b2b3b4 on x86, triggers magic nsa hole.
