\nIntel Xe grafikkort med st\u00f8tte for GPU SGX<\/i><\/p>\n

Siden kunngj\u00f8ringen om at Intel skal utvikle sitt eget diskrete grafikkort, har hele den progressive menneskeheten ventet p\u00e5 at planene skal bli til noe materielt. Det er fortsatt lite kjent om de tekniske detaljene, men i dag kan vi informere om noe konkret og viktig. Det er klart at det fremtidige grafikkortet fra Intel vil st\u00f8tte en teknologi som er analog med Intel SGX<\/a><\/noindex>, for super sikker lagring av spesielt viktig innhold \u2014 den kalles GPU SGX.
\n<\/a><\/noindex>
\nVi nevnte teknologiene til Intel Software Guard Extensions for ikke lenge siden i forbindelse med lanseringen av Intel SGX Card<\/a><\/noindex>. Intel SGX-utvidelser er et sett med CPU-instruksjoner som gir applikasjoner mulighet til \u00e5 opprette enclaves, beskyttede omr\u00e5der i applikasjonens adresseomr\u00e5de, som sikrer konfidensialitet og integritet, selv i n\u00e6rv\u00e6r av skadelig programvare med privilegerte rettigheter. <\/p>\n

Men beskyttelsen m\u00e5 ogs\u00e5 omfatte kj\u00f8rende kode og brukerdata. Legioner av angripere dr\u00f8mmer dag og natt om \u00e5 stjele bildene dine og deretter slette dem eller kryptere dem. Hvordan kan man unng\u00e5 \u00e5 miste de viktigste minnene? Her kan Intel SGX ogs\u00e5 komme til unnsetning, i sin variant GPU SGX. I dette tilfellet fungerer det p\u00e5 f\u00f8lgende m\u00e5te.<\/p>\n

\"Intel
\n
\nDen kjernende rollen i denne teknologien, som navnene antyder, spilles av grafikkprosessoren. \"Hva har grafikkortet med datalagring \u00e5 gj\u00f8re?\" \u2014 lurer du kanskje. Saken er at til tross for all respekt for Intel SGX, er det betydelig f\u00e6rre prosessorer som st\u00f8tter denne teknologien enn de som ikke gj\u00f8r det. Derfor ble det besluttet \u00e5 flytte utf\u00f8relsen av SGX-avhengig kode til GPU, p\u00e5 samme m\u00e5te som det er gjort med det allerede nevnte Intel SGX Card. Grafikkortet har ogs\u00e5 en annen fordel: dets konstruksjon gj\u00f8r det mulig \u00e5 plassere en betydelig mengde flash-minne p\u00e5 det, som kan brukes som lokal, beskyttet lagring.<\/p>\n

Principen bakom GPU SGX fungerar s\u00e5 h\u00e4r. Fotografi av din \u00e4lskade hund och andra s\u00e4rskilt viktiga data lagras p\u00e5 det lokala lagringsutrymmet p\u00e5 grafikkortet genom en specialiserad programvara fr\u00e5n Intel. Skyddet f\u00f6r Intel SGX fungerar p\u00e5 niv\u00e5n f\u00f6r filsystemdrivrutinen. D\u00e4refter synkroniserar den samma specialiserade programvara inneh\u00e5llet i lagringen med en molntj\u00e4nst i ett av de l\u00e4gen som anv\u00e4ndaren valt. Till skillnad fr\u00e5n andra molntj\u00e4nster kan Intel-klienten inte komprometteras, eftersom den placerar k\u00e4nsliga kodomr\u00e5den i SGX-anklag. P\u00e5 s\u00e5 s\u00e4tt f\u00e5r dina data flera skyddsniv\u00e5er mot st\u00f6ld och f\u00f6rst\u00f6relse.<\/p>\n

Vad h\u00e4nder om Intels programvara av n\u00e5gon anledning slutar fungera, och data bokstavligen blir inl\u00e5sta i sitt lagringsutrymme? Intel planerar att dela sin teknologi med tredjepartsf\u00f6retag baserat p\u00e5 strikt certifiering och kontroll. S\u00e5 det kommer att finnas ett alternativ. Men sj\u00e4lva systemet kommer inte att dyka upp p\u00e5 marknaden f\u00f6rr\u00e4n grafikkorten \u00e4r tillg\u00e4ngliga \u2014 tidslinjerna \u00e4r fortfarande oklara. Men vi v\u00e4ntar.
