On l\u00f5petatud matemaatilise formaalse verifitseerimise t\u00f6\u00f6 mikrokiibi seL4 usaldusv\u00e4\u00e4rsuse ja turvalisuse kohta AArch64 arhitektuuriga s\u00fcsteemides. Verifitseerimine seisneb seL4 t\u00f6\u00f6 korrektsete matemaatiliste t\u00f5endite koostamises, mis t\u00f5endavad t\u00e4ielikku vastavust formaalses keeles esitatud spetsifikatsioonidele. Usaldusv\u00e4\u00e4rsuse t\u00f5endamine v\u00f5imaldab kasutada seL4 kriitiliselt olulistes ARM64 arhitektuuriga s\u00fcsteemides, mis n\u00f5uavad k\u00f5rgemat turvalisuse taset ja garantii, et rikkepunkte ei esine. <\/p>\n

Alguses oli mikrokiip seL4 kinnitatud 32-bitiste ARM-protsessorite jaoks, hiljem aga 64-bitiste x86 ja RISC-V protsessorite jaoks. Verifitseerimine tagab, et kui \u00fches s\u00fcsteemi osas juhtub t\u00f5rge, siis see ei levita \u00fclej\u00e4\u00e4nud s\u00fcsteemile ja selle kriitilistele osadele. Turvalisuse tagamise kontekstis kinnitab verifitseerimine, et kiip tagab rakenduste sobiva isolatsiooni taseme, ei luba neil saada volitusteta ligip\u00e4\u00e4su teabele ning garanteerib, et kui sekundaarsed rakendused on ohustatud, ei levi r\u00fcnnak kriitilistele rakendustele. <\/p>\n

Mikrokiibi seL4 arhitektuur on t\u00e4helepanuv\u00e4\u00e4rne, kuna osade kernelite ressursside haldamine on viidud kasutajaruumi, rakendades neid samu juurdep\u00e4\u00e4sukontrolli meetodeid, mis on ette n\u00e4htud kasutajaressursside haldamiseks. Mikrokiip ei paku valmis k\u00f5rgema taseme abstraktsioone failide, protsesside, v\u00f5rgu\u00fchenduste jms haldamiseks, vaid pakub ainult minimaalset mehhanismi f\u00fc\u00fcsiliste aadressiruumide, katkestuste ja protsessori ressursside juurdep\u00e4\u00e4su haldamiseks. K\u00f5rgema taseme abstraktsioonid ja draiverid riistvaraga suhtlemiseks rakendatakse eraldi mikrokiibi pinnal kasutatavate \u00fclesannete kujul, mis toimuvad kasutaja tasemel. Aksesne nendel \u00fclesannetel olevate mikrokiibi ressursside valitsemiseks korraldatakse reeglite m\u00e4\u00e4ratlemise kaudu.
