asciilifeform: possibly textbook case for 'peh' from what I gather :) |
| 20:17 |
jfw |
but first I need to make it work at all before revisiting numerics. |
| 20:17 |
asciilifeform |
jfw: possibly. but i must admit that not yet tried to ecc under peh, there may be required number-theoretical knobs that are missing |
| 20:18 |
asciilifeform |
in re bitcoinism specifically -- the archaic hashes required are defo not in ('off the shelf') peh, likewise. |
| 20:20 |
jfw |
Nothing but grade-school arithmetic and modular inversion (which uses same) required for ECDSA. The 256-bit modular reductions are the slowest part for me afaik; hashing in Scheme slow too but not the bottleneck. |
| 20:29 |
asciilifeform |
theoretically oughta be easily 'pehable' then |
| 20:29 |

asciilifeform focused exclusively on rsa, to date, so not had chance to attempt |
| 20:29 |
asciilifeform |
jfw: re hashes, commented on your www . |
| 20:36 |
asciilifeform |
jfw: re ecc -- part of why asciilifeform avoided to implement ecc (even tho ultimately it must be done, for a solid btctron) is that safety-critical mechanisms imho oughta be implemented by people who ~understand~ how they work. i understand how rsa worx. but ecc, presently, not. |
| 20:37 |
jfw |
ty for that comment asciilifeform, makes good futher context. Isn't RSA in that same snake-oil category though? |
| 20:37 |
jfw |
one can understand what it does but factoring not proven to be "hard" |
| 20:37 |
asciilifeform |
jfw: not quite same. rsa rests on specific conjecture. |
| 20:38 |
asciilifeform |
indeed , factoring not-proven to be hard. |
| 20:38 |
asciilifeform |
( and , worse, rsa (unlike e.g. rabin's method) not afaik proven to rest entirely on the difficulty of factoring. ) |
| 20:40 |
asciilifeform |
however it is a number-theoretical method, and to date survived 4 decades of number-theoretical approach. unlike the transpository shell games which , historically, fell like rotten trees at 1st serious push. |
| 20:41 |
asciilifeform |
merely attempting to do a serious analysis of hash or symmcipher is painful enuff that there's scarcely any public material worth the mention re subj. |
| 20:42 |
asciilifeform |
this for instance is the best crit i've found re keccak. and even it, half bilgewater. |
| 20:43 |
jfw |
do you reckon anyone understands ECC in the sense you have in mind, beyond "code does what the paper says it should and we can't see how to break it yet" ? |
| 20:43 |
asciilifeform |
re symmciphers, ~100% of academitard analysis specifically sits on 'reduced round' (i.e. crippled) variants rather than the real thing |
| 20:43 |
asciilifeform |
jfw: it isn't clear to me that anyone understands it, in that (yes, you correctly summarized) sense. |
| 20:44 |
asciilifeform |
rather, beyond 'this is equiv. to what paper specified' sense. |
| 20:46 |
asciilifeform |
jfw: ecc also has an 'interesting' political history (usg pushed it aggressively for ~20y, and w/ entirely fraudulent claims of '256b ecc is equiv to 4096b rsa' etc) |
| 20:47 |
jfw |
alright. Sometimes the reduced rounds findings add up to real breakage, like with sha1, right? (I'm not well versed in cryptanalysis whether bilge or pure) |
| 20:47 |
asciilifeform |
for all i (or anyone else) know -- bitcoin per se orig was a constructed bomb, by fella who knows the boojum for ecc. |
| 20:47 |
asciilifeform |
jfw: sometimes indeed, but very rarely author of such material substantiates the claim of 'adds up to real break' |
