mircea_popescu: the evidently philosophically correct formulation is
the second, being positive not negative.
mircea_popescu: in any case,
the former statement is an exercise in psychotic nonsense. how
the fuck can you demand someone NOT be able
to whatever.
mircea_popescu: i suppose
to get fancy we're inquiring whether information is quantified. fine.
mircea_popescu: but anyway,
there's a difference between "it in principle exists" and anything useful.
mircea_popescu: "in any amount of water
there's some nonzero information as
to
the original solutes"
mircea_popescu: for instance,
the dillutionists propose a similar view of solutions.
mircea_popescu: (this being something i suspect mpfhf fambly MAY be amenable
to proving, but i've yet
to get anywhere)
mircea_popescu: "for as long as
the plaintext went
through alfhash, it is known as a mathematical fact, irrespecvtive of any considerations,
that so many steps must be undertaken
to undo it"
mircea_popescu: whereas in
the correct, crypto-relevant understanding of "hash is hard", what is said is "B can make grounded promise
that his effort will require at least X work"
☟︎ mircea_popescu: in
the common understanding of "hash is hard", what is said is "B can not make any grounded promise
that his effort will require less
than X work for an arbitrary item chosen by A"
mircea_popescu: a modelling in which b knows
the plaintext breaks
this definition, and it is
therefore not interesting.
mircea_popescu: the correct measurement of hash strength includes
two parties, defined as : party A, which knows
the plaintext and computes
the hash ; and party B, which does not know
the plaintext and computes it on
the basis of nothing but
the hash.
mircea_popescu: i don't care
that "on average it's 5
trillion but for
the value you chose it's
two weeks"
mircea_popescu: what interests me, when you say "alfhash is 5
trillion hours strong" is
that ANY VALUE i pass into alfhash will be reversed in NO LESS
than 5
trillion hours.
mircea_popescu: trivially
the average, weighted or not, will be inside
the domain and not
the lower bound of
the domain.
mircea_popescu: the point of interest for
the "max case" is b.
the point of interest
to us is a.
the "average case" is either a+b/2 or else ni * weight i / sum i.
mircea_popescu: consider
the work required
to reverse it has been calculated for each value, and is in
the domain [a, b].
mircea_popescu: suppose
there's a function
that does hashing over a domain consisting of 2^100 possible distinct values.
mircea_popescu: we're not discussing
that nonsense. we're discussing
the actual blind case.
mircea_popescu: average case has no value for
this later branch ; has some limited value for
the former branch,
to see how "eccentric"
the upper bound is.
a111: Logged on 2017-09-28 15:09 asciilifeform:
the fundamental boojum preventing anything like a rationally designed blockcipher-hash-prng , is
that we do not actually have a
theory of average-case problem hardness.
mircea_popescu:
http://btcbase.org/log/2017-09-28#1718015 << minimum case.
the average case is of relatively little interest here. what interests is hardest case,
to design solutions for problems (what is currently 100% of all
theoretic work done), and minimum case,
to guarantee hardness, which is 0% of work done and 100% of republican interest.
☝︎ a111: Logged on 2017-09-28 15:00 asciilifeform: ( and it is entirely conceivable
that some variation on
the
theme of bbp's function will give you a fast search for 'where in pi might
this fuzzy match be' and
the like )
a111: Logged on 2017-09-28 14:53 asciilifeform: 'Given
the “stark difference between
the abnormal rate and
the actual market prices of bitcoin and ethereum on April 19”, B2C2, which Quoine called a “sophisticated” investor with experience
trading virtual currencies, should have suspected
the “abnormal rate” was a mistake. '
ben_vulpes: what are
these mysterycrates, asciilifeform ?!
BingoBoingo: "That's exactly
the problem. Yesterday I ate a most delicious desert out of my slavegirl's own ass, directly.
This dream of many previous sultans and whatnots
that nevertheless couldn't ever be fulfilled effortlessly came
through, for me. I didn't even much care for it either way," <<

☟︎ ben_vulpes: trying
to find
this
thread and failing
ben_vulpes: cruciform: gpg keys of greater
than 2048 bits expose you
to retardation in gpg as well
trinque: k, I guess
that was
the last one
trinque: you generated
this key on windows, right?
trinque: well, if you're going
to go
to
this
trouble, consider a few other
things.
trinque: there's no automatic way
to change your key. sign a full export of a new public key with an old one and I'll make
the change.
a111: Logged on 2017-03-02 18:09 asciilifeform: ok i cannot resist answering ben_vulpes . because he will find answer in encyclopaedia, but it will not be an actual answer, but only a
thought-extinguisher.

the way
this conversation is going, we can't have children us
two until we get
the baby room properly furnished and
the safest crypto op is one
that never finishes.
a111: Logged on 2017-09-20 19:28 asciilifeform: incidentally iirc we did
the proof of 'if
there is a good hash,
there is a good blockcipher, and vice-versa'
a111: Logged on 2017-09-28 09:39 mircea_popescu: not necessarily
the specific example. but yes, symmetric cipher always reduces
to a "parametrized otp".
a111: Logged on 2017-09-27 20:31 mircea_popescu: "your honor, i'm smarter
than
the inca, natch" ?
shinohai: *05:48:42 <-- mac_____ (rm@goat.sex) has quit (Ping
timeout: 260 seconds)
mircea_popescu: best do it upfront
than fucking your own ass with boxes and bs.
mircea_popescu: not necessarily
the specific example. but yes, symmetric cipher always reduces
to a "parametrized otp".
☟︎ mircea_popescu: ben_vulpes yeah, not bad. i still hold
that's
the ~only avenue
to
the problem.
BingoBoingo: I'd suspect etherhufferium, Chicoms seem
to have more juice
to
throw at crash

the average age of shipyard capital equipment now exceeds its expected useful life.
ben_vulpes: while i am definitely guilty of eking a half-decade out of a lathe with judicious application of idle six-axis arms found elsewhere in
the facility, i don't
think even
the screw machine squad's hardware was mostly within expected lifespans.

☟︎ ben_vulpes: just
the usn, eh? did we do
the most recent los alamos fuckups?
ben_vulpes: > Roy Moore was further endorsed by President
Trump announced his intention
to enthusiastically campaign for Moore in
the event Moore came out on
top in
the runoff. <<
there is something missing in
this sentence, between President
Trump and announced, i
think.
