\nIntel Xe graafikakaart GPU SGX toega<\/i><\/p>\n

Alates hetkest, mil Intel teatas oma eraldi graafikakaardi v\u00e4ljat\u00f6\u00f6tamisest, on kogu arenev inimkond oodanud, millal plaanid hakkavad vormuma midagi k\u00e4egakatsutavat. Tehnilisi \u00fcksikasju on siiani teada v\u00e4he, kuid t\u00e4na saame jagada m\u00f5ned konkreetsed ja olulised uudised. On selgunud, et tulevane Intel graafikakaart toetab tehnoloogiat, mis on analoogne Intel SGX<\/a><\/noindex>, et superturvaliseks oluliste andmete hoidmiseks \u2014 seda nimetatakse GPU SGX-iks.
\n<\/a><\/noindex>
\nMe r\u00e4\u00e4kisime Intel Software Guard Extensions tehnoloogiast hiljuti seoses Intel SGX kaardi<\/a><\/noindex>. Intel SGX laiendused on protsessori k\u00e4su komplekt, mis v\u00f5imaldab rakendustel luua anklave, kaitstud alasid rakenduse aadressiruumi sees, tagades privaatsuse ja terviklikkuse isegi siis, kui pahavara omab \u00f5igusi. <\/p>\n

Kaitsta tuleb mitte ainult t\u00e4ituvat koodi, vaid ka kasutaja andmeid. R\u00f6\u00f6vlite leegionid unistavad \u00f6\u00f6p\u00e4evaringselt, kuidas teie fotosid varastada, et need hiljem kustutada v\u00f5i kr\u00fcpteerida. Kuidas mitte j\u00e4\u00e4da ilma oma k\u00f5ige olulisematest m\u00e4lestustest? Siin aitab samuti Intel SGX, oma versioonis GPU SGX. Sel juhul t\u00f6\u00f6tab see j\u00e4rgmiselt.<\/p>\n

\"Intel
\n
\nSelle tehnoloogia keskne roll, nagu nimi \u00fctleb, on graafikaprotsessoril. \"Kuidas on graafikakaardiga seotud andmete hoidmine?\" \u2014 v\u00f5ib-olla k\u00fcsite te. Asi on selles, et vaatamata Intel SGX-i respekteerimisele on protsessoreid, mis toetavad seda tehnoloogiat, oluliselt v\u00e4hem kui neid, mis ei toeta. Seet\u00f5ttu otsustati SGX-ilt s\u00f5ltuva koodi t\u00e4itmine \u00fcle kanda GPU-le, sarnaselt juba mainitud Intel SGX kaardile. Graafikakaardil on veel \u00fcks eelis: selle konstruktsioon v\u00f5imaldab tal paigutada piisavalt suurt hulka Flash-m\u00e4lu, mida saab kasutada kui kohalikku kaitstud salvestusruumi.<\/p>\n

GPU SGX t\u00f6\u00f6p\u00f5him\u00f5te on j\u00e4rgmine. Armastuse koera fotosid ja muid erilisi olulisi andmeid salvestatakse graafikakaardi kohalikku salvestusruumi spetsiaalse Intel tarkvara abil. Intel SGX kaitse t\u00f6\u00f6tab failis\u00fcsteemi draiveri tasemel. Seej\u00e4rel s\u00fcnkroniseerib sama spetsiaalne tarkvara salvestusruumi sisu valitud kasutaja re\u017eiimis pilveteenusega. Erinevalt teistest pilveteenustest ei saa Intel klient olla kompromiteeritud, kuna see asetab tundlikud koodipiirkonnad SGX anklavatesse. Seega saavad teie andmed mitmeid kaitseastmeid varguse ja h\u00e4vitamise eest.<\/p>\n

Aga mis juhtub, kui Intel tarkvara mingitel p\u00f5hjustel l\u00f5petab t\u00f6\u00f6tamise ja andmed j\u00e4\u00e4vad s\u00f5na otseses m\u00f5ttes oma salvestusse kinni? Intel plaanib jagada oma tehnoloogiat kolmandate ettev\u00f5tetega rangete sertifitseerimise ja kontrollimise alusel. Nii et alternatiiv on olemas. K\u00fcll aga ei ilmu s\u00fcsteem turule enne graafikakaartide tulekut \u2014 t\u00e4htaegu ei ole siiani selge. Kuid me ootame.
