Ikhadi lemizobo le-Intel Xe elinenkxaso yeSGX GPU
Ukusukela ngalo mzuzu wesibhengezo sokuba i-Intel iza kuphuhlisa ikhadi layo levidiyo, bonke abantu abaqhubela phambili belinde ukuba izicwangciso ziqale ukuguqula zibe yinto ebonakalayo. Zimbalwa iinkcukacha zobugcisa ezaziwayo okwangoku, kodwa namhlanje sinokuxela into ebambekayo kwaye ibalulekile. Kuye kwaziwa ukuba ikhadi levidiyo le-Intel elizayo liya kuxhasa iteknoloji efana nayo , ukugcinwa okuthembekileyo okuphezulu komxholo obaluleke kakhulu-ubizwa ngokuba yiGPU SGX.
Sikhankanye itekhnoloji yoLwandiso lweTekhnoloji ye-Intel kutshanje ngokunxulumene ne . Izandiso ze-Intel SGX yiseti yemiyalelo ye-CPU eyenza ukuba izicelo zenze i-enclaves, imimandla ekhuselweyo kwindawo yedilesi yesicelo enikezela ubumfihlo kunye nokunyaniseka nangona kukho i-malware enelungelo.
Kodwa ayisiyiyo kuphela ikhowudi yophumezo ekufuneka ikhuselwe, kodwa kunye nedatha yomsebenzisi. Imikhosi yabaphuli mthetho iphupha imini nobusuku malunga nokuba iifoto zakho kwaye uzicime okanye uzifihle. Indlela yokungashiywa ngaphandle kwezona nkumbulo zibalulekileyo? I-Intel SGX, kuluhlu lwayo lwe-GPU SGX, inokuhlangula apha. Kule meko isebenza ngolu hlobo lulandelayo.
Indima ephambili kule teknoloji, njengoko igama libonisa, idlalwe yiprosesa yemizobo. "Ikhadi levidiyo lidibana ngantoni nalo xa kufikwa kugcino lwedatha?" - mhlawumbi uyabuza. Inyani yeyokuba ngayo yonke intlonipho ye-Intel SGX, kukho iiprosesa ezimbalwa ezixhasa le teknoloji kunezo zingayixhasiyo. Ngoko ke, kwagqitywa ekubeni kudluliselwe ukuphunyezwa kwekhowudi exhomekeke kwi-SGX kwi-GPU, efana nendlela eyenziwe ngayo kwiKhadi le-Intel SGX esele ikhankanyiwe. Ikhadi levidiyo linenzuzo enye ngakumbi: uyilo lwayo livumela ukuba lifake inani elikhulu ngokufanelekileyo lememori ye-flash, enokusetyenziswa njengendawo yokugcina indawo ekhuselweyo.
Umgaqo wokusebenza weGPU SGX umi ngolu hlobo lulandelayo. Iifoto zenja oyithandayo, kunye nezinye iinkcukacha ezibalulekileyo, zibekwe kwindawo yokugcina ikhadi levidiyo usebenzisa i-Intel software ekhethekileyo. Ukhuseleko lwe-Intel SGX lusebenza kwinqanaba lomqhubi wefayile. Emva koko, isoftware ekhethekileyo efanayo idibanisa imixholo yogcino kunye nenkonzo yelifu kwenye yeendlela ezikhethwe ngabasebenzisi. Ngokungafaniyo nezinye iinkonzo zelifu, umxhasi we-Intel akanako ukuthotywa ngenxa yokuba ibamba iindawo zekhowudi ezibuthathaka kwi-SGX enclaves. Ke, idatha yakho ifumana amanqanaba amaninzi okhuseleko kubusela kunye nokutshatyalaliswa.
Kwenzeka ntoni ukuba isoftware ye-Intel iyeka ukusebenza ngesizathu esithile kwaye idatha itshixiwe ngokoqobo kwindawo yokugcina? I-Intel ilindele ukwabelana ngeteknoloji kunye namaqela esithathu ngokusekelwe kwisatifikethi esingqongqo kunye nolawulo. Ngoko kuya kubakho enye indlela. Ewe, inkqubo ngokwayo iya kubonakala kwimarike ngaphambi kokubonakala kwamakhadi evidiyo ngokwawo - ixesha lisacacile. Kodwa siza kulinda.
