Dokon\u010dano je delo na matemati\u010dni formalni verifikaciji zanesljivosti in varnosti delovanja mikrojedra seL4 na sistemih z arhitekturo nabora ukazov AArch64. Verifikacija se zmanj\u0161uje na matemati\u010dni dokaz pravilnosti delovanja seL4, kar pomeni popolno skladnost s specifikacijami, dolo\u010denimi v formalnem jeziku. Dokaz zanesljivosti omogo\u010da uporabo seL4 v kriti\u010dnih sistemih, ki temeljijo na ARM64 procesorjih, ki zahtevajo vi\u0161jo raven varnosti ter zagotavljajo odsotnost napak. <\/p>\n

Sprva je bilo mikrojedro seL4 verificirano za 32-bitne ARM procesorje, nato pa za 64-bitne x86 in RISC-V procesorje. Verifikacija zagotavlja, da v primeru napake v enem delu sistema ta napaka ne bo vplivala na preostali sistem in njegove kriti\u010dne dele. V kontekstu zagotavljanja varnosti verifikacija potrjuje, da jedro zagotavlja ustrezen nivo izolacije aplikacij, ne dovoljuje jim dostopa do informacij brez avtorizacije in zagotavlja, da v primeru kompromitacije sekundarnih aplikacij napad ne bo pre\u0161el na kriti\u010dne pomembne aplikacije. <\/p>\n

Arhitektura mikrojedra seL4 se odlikuje po tem, da del\u010dke za upravljanje virov jedra prena\u0161a v uporabni\u0161ki prostor in uporablja za te vire iste metode za nadzor dostopa, kot za uporabni\u0161ke vire. Mikrojedro ne ponuja pripravljene visoko nivojske abstrakcije za upravljanje datotek, procesov, omre\u017enih povezav itd., temve\u010d zagotavlja le minimalne mehanizme za upravljanje dostopa do fizi\u010dnega naslovnega prostora, prekinitev in virov procesorja. Visoko nivojske abstrakcije in gonilniki za interakcijo s strojno opremo se izvajajo lo\u010deno nad mikrojedrom v obliki nalog, ki se izvajajo na uporabni\u0161ki ravni. Dostop teh nalog do virov mikrojedra je organiziran z dolo\u010danjem pravil.
