Ubumenyi shingiro Amabanga
Gufunga amakuru mu buryo bw'ibanga
Ibibazo byawe n'ibisubizo byabyo bishingiye ku bwigenge bwuzuye (end-to-end encrypted), biriho n'urwego rw'ubwigenge rurwambutse imiterere nshya ya tekinoloji (post-quantum layer) ruri hejuru y'urwego rwa kera. Iyi urubuga ivuga ku byo ibi birinda nyamukuru.
Uru rupapuro rwahinduwe imashini kugirango byorohe. Umwimerere wicyongereza ni verisiyo ikoreshwa.
End-to-end by default
Nta miterere yo kuyakora yo iri, kuko ubutumwa bwose mu biganiro byose buhashingwa kuri icyitandaro cyawe mbere y'uko biba mu bindi, hanyuma bukanasubizwa mu buryo bugaragara ku wundi mpande. Abaguza ubutumwa ntashobora kubusoma, kandi na byose biri hagati yabyo ntibishobora kubusoma.
"Uruhande rindi" hano ni serivisi ya Nymbot, igomba gusoma ikibazo cyawe kugira ngo igisubize. End-to-end bivuze ko nta muntu else bishoboka — ntibivuze kandi ntibishoboka ko umufasha asubiza ikintu atigeze abona. Uburyo bwo kutagaragara ese igisubizo cy'ikibazo kitandukanye cy'aho igikwiye kumenya ni nde byajijwe.
Impapuro zo gufukira impano
Ubutumwa bugenda nk'impapuro zizura impano za Nostr. Buri kimwe kirimo amashyirwarubanza atatu:
- a ibihuha — ubutumwa ubwacyo, butariho umukono, kugira ngo ntibishobore kwemeza imbere urundi rubanza;
- a kashe, ikiyanditse nawe kandi ikaba yafunze kugira ngo igere ku ukiyanditse, ukoresheje uburyo uwo ukiyanditse abasha kumenya uwayihaye;
- a ubunonnye, byashyizweho ikimenyetso kandi ikaba yafunzwe hakoreshejwe urufunguzo rw'ikoreshwa rimwe gusa, cyo ari cyo gusa ibyo ubufatanyabikorwa (relay) biba bubona.
Nuko ubufatanyabikorwa (relay) buhuza umuyoboro wawe bubona ibimenyetso biva kuri urutonde (key) ruriho gusa kuri uwo muntu, rubonye n'igihe (timestamp) kitari cyihariye — bushobora kumenya ko ubutumwa ari ubw'i Nymbot, ariko si uwo butumwa buturuka. Isuzuma ry'amakuru y'inyongezo (metadata) rishingiye ku bupfundo (wraps) rirangwa n'ibintu bike cyane.
Icopy ya buri butumwa na yo ihuzwa n'urugero rwawe rwihariye, ni uburyo amateka yawe akurikirana ku gikoresho gishya binyuze mu banyamubugenzurizi aho gukoresha inyandiko ziri kuri seriveri.
Ikinyuranyo cy'uburyo bushya n'ubw'umwaka w'ibitekerezo (Post-quantum hybrid)
Icyerekezo cy'ibanze ni elliptic-curve. Mudasobwa ya quantum ihagije ishobora kubivunura inyuma — amakuru yakusanyijwe uyu munsi, akavunurwa nyuma y'imyaka. Ni therefore uburyo bwo gukoresha encryption ni ihuzabintu: uburyo bwo guhagarika amakuru bwa ML-KEM buhuza n'uburyo bwa kera bwo guhinduranaho amakuru, kandi umugambanyi agomba kurwanya byose kugira ngo asome ikintu cyose.
ML-KEM ni KEM y'urubaho (lattice) yemejwe n'ikigo cya NIST. Guhuza aho gusimbuza ni icyemezo cyateguwe: niba igitekerezo cy'urubaho (lattice assumption) kigaragaza ko ari ukweli, ukaba ucyari ufite elliptic curve, ndetse n'ubundi buryo n'ubwo.
Nymbot ishyira hanze itangazo ry'ubushobozi ryafasinywe ryikubiyemo urufunguzo rwayo rwa KEM, kugira ngo porogaramu yawe ibashe kuyifunga nta nkomyi zo gushaka amakuru (lookup race) zagira ubutumwa buba bwiganije uburyo bwa kera gusa (classical-only). Porogaramu yawe na yo ishyira hanze itangazo nk'iryo, kandi ibyo nibyo bituma ubusubizo buza bukoresha uburyo bwiyunze (hybrid).
