Utvecklarna av det anonyma n\u00e4tverket Tor har presenterat projektet Arti, d\u00e4r arbete p\u00e5g\u00e5r f\u00f6r att skapa en implementation av Tor-protokollet i Rust. Till skillnad fr\u00e5n implementationen i C, som f\u00f6rst designades som en SOCKS-proxy och sedan anpassades f\u00f6r andra behov, utvecklas Arti fr\u00e5n b\u00f6rjan som en modul\u00e4r, inb\u00e4ddad biblioteksform som olika applikationer kan anv\u00e4nda. Arbetet har p\u00e5g\u00e5tt i \u00f6ver ett \u00e5r med finansiering fr\u00e5n Zcash Open Major Grants (ZOMG). Koden distribueras under licenserna Apache 2.0 och MIT. <\/p>\n

Anledningen till att Tor skrivs om i Rust \u00e4r att uppn\u00e5 en h\u00f6gre grad av kods\u00e4kerhet genom att anv\u00e4nda ett spr\u00e5k som erbjuder s\u00e4ker minneshantering. Enligt Tor-utvecklarna kommer minst h\u00e4lften av alla s\u00e5rbarheter som projektet sp\u00e5rar att eliminieras i implementationen i Rust, s\u00e5 l\u00e4nge koden inte inneh\u00e5ller «unsafe» block. Rust g\u00f6r det ocks\u00e5 m\u00f6jligt att uppn\u00e5 en h\u00f6gre utvecklingshastighet j\u00e4mf\u00f6rt med C, tack vare spr\u00e5kets uttryckskraft och strikta garantier som minskar behovet av dubbla kontroller och on\u00f6dig kod. Dessutom beaktas i utvecklingen av det nya projektet all tidigare erfarenhet fr\u00e5n Tor, vilket g\u00f6r att k\u00e4nda arkitekturproblem kan undvikas och projektet kan bli mer modul\u00e4rt och effektivt. <\/p>\n

I sitt nuvarande tillst\u00e5nd kan Arti redan ansluta till Tor-n\u00e4tverket, s\u00e4kerst\u00e4lla interaktion med servrar<\/a> kataloger och skapa anonymiserade anslutningar ovanp\u00e5 Tor med tillhandah\u00e5llande av en proxy baserad p\u00e5 SOCKS-protokollet. Utvecklingen rekommenderas \u00e4nnu inte f\u00f6r anv\u00e4ndning i produktionssystem, eftersom alla funktioner f\u00f6r att s\u00e4kerst\u00e4lla konfidentialitet inte \u00e4r implementerade och bak\u00e5tkompatibilitet p\u00e5 API-niv\u00e5 inte garanteras. Den f\u00f6rsta versionen av klienten, som uppfyller s\u00e4kerhetskriterier, st\u00f6djer \u00f6vervakningsnoder och isolering av str\u00f6mmar, planeras att sl\u00e4ppas i oktober. <\/p>\n

I mars 2022 f\u00f6rv\u00e4ntas den f\u00f6rsta beta-versionen med en experimentell implementation av det inbyggda biblioteket och prestandaoptimeringar. Den f\u00f6rsta stabila versionen, med stabilt API, CLI och konfigurationsformat, samt en genomf\u00f6rd revision, \u00e4r planerad till mitten av september 2022. Denna version kommer att vara anv\u00e4ndbar f\u00f6r grundl\u00e4ggande anv\u00e4ndning av vanliga anv\u00e4ndare. I slutet av oktober 2022 f\u00f6rv\u00e4ntas uppdatering 1.1 med st\u00f6d f\u00f6r plug-in transport och broar f\u00f6r att kringg\u00e5 blockeringar. St\u00f6d f\u00f6r onion-tj\u00e4nster \u00e4r planerat till version 1.2, medan uppn\u00e5endet av paritet med klienten i C-spr\u00e5ket f\u00f6rv\u00e4ntas i version 2.0, vars tidsramar \u00e4nnu inte har fastst\u00e4llts. <\/p>\n

Fram\u00f6ver f\u00f6rutser utvecklarna en gradvis minskning av aktiviteten relaterad till kodutveckling i C-spr\u00e5ket, och en \u00f6kning av tiden som \u00e4gnas \u00e5t redigering i Rust. N\u00e4r implementeringen i Rust n\u00e5r en niv\u00e5 som kan ers\u00e4tta C-versionen, kommer utvecklarna att sluta l\u00e4gga till nya funktioner i C-implementationen och efter en tid helt avsluta dess st\u00f6d. Men det kommer inte att h\u00e4nda snart, och s\u00e5 l\u00e4nge implementationen i Rust inte n\u00e5r niv\u00e5n av en fullst\u00e4ndig ers\u00e4ttning kommer utvecklingen av Tor-klienten och rel\u00e4et i C att forts\u00e4tta.
