Uues GrapheneOS 2024053100 versioonis on lisatud funktsioon, mis v\u00f5imaldab seadme andmeid h\u00e4daolukorras lukustada. Kasutajal on v\u00f5imalik seada t\u00e4iendav salas\u00f5na ja PIN-kood, mille sisestamine viib k\u00f5ikide v\u00f5tmete kustutamiseni riistvaras, sealhulgas nende v\u00f5tmete, mis on seotud andmete kr\u00fcpteerimisega salvestusruumis, samuti eSIM-i kustutamisele ja seadme taask\u00e4ivitamisele. Seega, kui kasutaja satub surve alla v\u00f5i teda sunnitakse ekraani avama, v\u00f5i kui on oht, et nutitelefon satub valedesse k\u00e4tesse, saab seadme omanik sisestada kahjuliku PIN-koodi ja lukustada andmed ilma juurdep\u00e4\u00e4su taastamiseta. <\/p>\n

GrapheneOS projekt arendab Androidi koodeksi (AOSP, Android Open Source Project) haru, mis on laiendatud ja muudetud, et suurendada turvalisust ja tagada privaatsust. Enamik praegustest Google Pixel seadmetest (Pixel 4\/5\/6\/7\/8, Pixel Fold, Pixel Tablet) on ametlikult toetatud. Projekti arendused jaotatakse MIT litsentsi alusel. Kompositsioon sisaldab mitmeid eksperimentaalseid tehnoloogiaid, mis on seotud rakenduste isolatsioonide suurendamise, juurdep\u00e4\u00e4su detailse haldamise, tavaliste haavatavuste ilmingute blokeerimise ja eksploitide t\u00f6\u00f6 raskendamisega. <\/p>\n

N\u00e4iteks kasutatakse platvormil oma malloc teostust ja muudetud libc versiooni, mis kaitseb m\u00e4lu kahjustamise eest, samuti rangemat protsesside aadressiruumi eraldamist. Android Runtime'is kasutatakse ainult ettevaatlikku (AOT, ahead-of-time) kompileerimist JIT asemel. Linuxi tuumas on lisatud mitmeid t\u00e4iendavaid kaitsemehhanisme, n\u00e4iteks slub'is lisatakse kanaruutud sildid, et blokeerida puhver\u00fclekandeid. Rakenduste isolatsiooni suurendamiseks on kaasatud SELinux ja seccomp-bpf. <\/p>\n

On olemas v\u00f5imalus anda teatud rakendustele valikuline juurdep\u00e4\u00e4s v\u00f5rguoperatsioonidele, anduritavale, aadressiraamatule ja v\u00e4lisseadmetele (USB, kaamera). Vaikimisi on keelatud teabe saamine IMEI, MAC-aadressi, SIM-kaardi seerianumbri ja teiste riistvaraliste identifikaatorite kohta. Ahnkustekleidime lubatakse ainult neis rakendustes, kus fookus sisendis parajasti on. Lisameetmed Wi-Fi ja Bluetoothi seotud protsesside isolatsiooniks on aktiveeritud, et v\u00e4ltida lekkeid juhtmete kaudu. Paljud projektis arendatud turvameetmed on viidud Androidi p\u00f5hikoodibaasi. <\/p>\n

GrapheneOS-is rakendatakse kr\u00fcptograafilist kontrolli laaditud komponentide \u00fcle ja ulatuslikku andmete kr\u00fcpteerimist<\/a> failis\u00fcsteemide ext4 ja f2fs tasemel (andmed kr\u00fcpteeritakse AES-256-XTS abil, failide nimed \u2014 AES-256-CTS, kasutades HKDF-SHA512 eraldi v\u00f5tme genereerimiseks iga faili jaoks), mitte plokiajamite tasemel. Andmed s\u00fcsteemiosades ja igas kasutaja profiilis kr\u00fcpteeritakse erinevate v\u00f5titena. Kr\u00fcpteerimise operatsioonide kiirendamiseks kasutatakse saadaval olevaid riistvaralisi v\u00f5imalusi. Lukku pandud ekraanil kuvatakse sessiooni l\u00f5petamise nupp, millele vajutades t\u00fchistatakse dekr\u00fcpteerimisv\u00f5tmed ja salvestus seatakse mitteaktiivsesse olekusse. Valitud kasutajaprofiilides on seadistus t\u00e4iendavate rakenduste paigaldamise keelamiseks. Paroolir\u00fcnnakute kaitsmiseks on kasutusel viivituste s\u00fcsteem, mis s\u00f5ltub vale proovimise arvust (30 sekundist kuni 1 p\u00e4evani). <\/p>\n

GrapheneOS ei p\u00f5him\u00f5tteliselt ei h\u00f5lma Google'i rakendusi ja teenuseid ega ka alternatiivseid Google'i teenuste teostusi, nagu microG. Siiski on v\u00f5imalik installida Google Play teenuseid eraldi isoleeritud keskkonnas, millel ei ole erilisi privileege. Projekti raames arendatakse ka mitmeid enda rakendusi, mis keskenduvad teabe ja privaatsuse kaitsele. N\u00e4iteks pakutakse Chromiumil p\u00f5hinevat veebibrauserit Vanadium, modifitseeritud WebView mootorit, turvatud PDF-vaaturit, tulem\u00fc\u00fcri, rakendust Auditor seadmete t\u00f5endamiseks ja sissetungi tuvastamiseks, kaamerarakendust, mis on suunatud privaatsuse tagamisele, ning Seedvaulti, mis loob kr\u00fcpteeritud varukoopiaid.
