Udviklerne af det anonyme netv\u00e6rk Tor har pr\u00e6senteret projektet Arti, som arbejder p\u00e5 at skabe en implementering af Tor-protokollen i Rust-sprog. I mods\u00e6tning til implementeringen i C, der oprindeligt blev designet som en SOCKS-proxy og f\u00f8rst senere tilpasset andre behov, udvikles Arti fra starten som et modul\u00e6rt indbygget bibliotek, som forskellige applikationer kan bruge. Arbejdet har st\u00e5et p\u00e5 i mere end et \u00e5r med finansiering fra Zcash Open Major Grants (ZOMG) programmet. Koden distribueres under Apache 2.0 og MIT-licenserne. <\/p>\n

Som \u00e5rsagerne til at genwrite Tor i Rust n\u00e6vnes \u00f8nsket om at opn\u00e5 en h\u00f8jere grad af code-sikkerhed gennem brugen af et sprog, der sikrer sikkerhed ved h\u00e5ndtering af hukommelsen. If\u00f8lge Tor-udviklerne vil mindst halvdelen af alle s\u00e5rbarheder, der spores af projektet, blive udelukket i implementeringen i Rust, hvis der ikke anvendes \"unsafe\"-blokke i koden. Rust vil ogs\u00e5 muligg\u00f8re en hurtigere udviklingshastighed end ved brug af C, takket v\u00e6re sprogets udtryksfuldhed og strenge garantier, der g\u00f8r det muligt at undg\u00e5 tidsspilde p\u00e5 dobbeltkontroller og un\u00f8dvendig kode. Desuden tages der h\u00f8jde for al tidligere erfaring fra udviklingen af Tor i udviklingen af det nye projekt, hvilket vil hj\u00e6lpe med at undg\u00e5 kendte arkitektoniske problemer og g\u00f8re projektet mere modul\u00e6rt og effektivt. <\/p>\n

I sin nuv\u00e6rende tilstand kan Arti allerede forbinde sig til Tor-netv\u00e6rket og sikre interaktion med servere<\/a> direktorier og oprette anonymiserede forbindelser oven p\u00e5 Tor med en SOCKS-baseret proxy. Det anbefales ikke at bruge udviklingen i produktionssystemer, da ikke alle funktioner til at sikre fortrolighed er implementeret, og der er ingen garanti for bagudkompatibilitet p\u00e5 API-niveau. Den f\u00f8rste version af klienten, der opfylder sikkerhedskriterierne og underst\u00f8tter overv\u00e5gningsknuder og isolering af str\u00f8mme, forventes at blive udgivet i oktober. <\/p>\n

I marts 2022 forventes den f\u00f8rste betaudgave med en eksperimentel implementering af den indbyggede bibliotek og ydeevneoptimeringer. Den f\u00f8rste stabile udgave, med et stabilt API, CLI og konfigurationsformat, samt en audit, er planlagt til midten af september 2022. Denne udgave vil v\u00e6re egnet til grundl\u00e6ggende brug af almindelige brugere. I slutningen af oktober 2022 forventes opdatering 1.1 med support til tilsluttede transportformer og broer for at omg\u00e5 blokeringer. Support til onion-tjenester er planlagt til udgave 1.2, mens opn\u00e5else af paritet med klienten skrevet i C er forventet i udgave 2.0, hvis tidsrammer endnu ikke er defineret. <\/p>\n

Fremover forudser udviklerne en gradvis reduktion i aktiviteten relateret til C-kodeudvikling og en stigning i den tid, der bruges p\u00e5 redigering i Rust. N\u00e5r implementeringen i Rust n\u00e5r et niveau, der kan erstatte C-versionen, vil udviklerne stoppe med at tilf\u00f8je nye funktioner til C-implementeringen og efterh\u00e5nden helt stoppe dens support. Men det vil ikke ske snart, og indtil Rust-implementeringen n\u00e5r et niveau af fuld erstatning, vil udviklingen af klienten og Tor-rel\u00e6erne i C forts\u00e6tte.
