Logged on 2020-08-20 19:00:15 asciilifeform: it is also the case that rng as commercial product is a very questionable biz proposition. it takes quite a bit of 'adulthood' to even get to a place where you actually benefit from a 1000 $ rng. for instance, microshit victims dun really win anyffin from using whatever external rng.

asciilifeform: since the pest getdata does, and more or less has to, bypass the staleness check, the whole checking of stales may be useless. even 'future' messages will eventually get through (even if a now omitted getdata future check was specified). OTOH, if you don't bother with checking stales, you now get more accurate reception timestamps of these badly timestamped messages, and more accurate picture of what's (been) going on

10:12

fwiw, in my possibly uneducated opinion, i find the 'my name is' msg type meaningful. cuz a selfchain is a more fitting item to label, than a single msg. while msgs in a selfchain have most of the time the same handle.

(pest) 2022-07-15 asciilifeform[signpost|billymg]: can't find thread atm, but at one pt suggested nixing the 'speaker' field entirely, in favour of a 'i'm x' msg type, which folx dredge outta log

10:22

asciilifeform: does this affect your intent to implement the 'chain locking', or still want it the same? if still the same, how do you view 'deterministic S-turd' approaches, like: "S-turd := HASH(S0 + chain_msg_seq_no)"?

Logged on 2022-01-26 18:48:29 asciilifeform: thimbronion: current notion, summarized: we bite off 64byte from payload, and get 2 new fields, call'em 'unlock' and 'lock'. lock == h256(errything else in msg, incl. 'unlock', and unrevealed 32byte turd 'S'.); unlock = 'S' from yer previous msg.

asciilifeform: peer B sent funny timestamps first, then sent a good one to a common peer C of A and B. C now getdatas the funny items and sends the latest, good one to A. A concludes a broken chain, and getdatas also the funny items from C

11:49

(at least for me personally) hard-to-picture scenarios like above, seem to exist how the stale check is bypassed, and hence seems cleaner to not try to force a peer to behave. instead let him spam or let his clock drift, and let the problem show up as is, with minimal indirection and gotchas. then you can decide whether some action required

irc-variant could simply show console warnings, with given msg and station-local timestamp comparisons

but ^ i accidentally forgot the replay attack angle...

12:45

cgra: aha, timestampism is specifically against replays, rather than 'make peer behave'

12:46

i.e. a peer can of course construct an arbitrarily-long chain that'll skip the staleness test. but a stranger -- cannot.

(trilema) 2017-08-22 asciilifeform: as for diffie hellman, it is nsatronic , and this is fairly well known at this point ( whether because timing side channel, primes-which-ain't, and other sabotage of concrete implementations- or more fundamentally broken - is unknown )
