Intel Xe mifananidzo kadhi ine SGX GPU rutsigiro
Kubva panguva chaiyo yechiziviso chekuti Intel yaizogadzira yayo discrete vhidhiyo kadhi, vanhu vese vanofambira mberi vanga vakamirira kuti zvirongwa zvitange kushandura kuita chimwe chinhu chinobatika. Mashoma ehunyanzvi ruzivo achiri kuzivikanwa, asi nhasi isu tinogona kuudza chimwe chinhu kongiri uye chakakoshawo. Izvo zvave kuzivikanwa kuti ramangwana reIntel vhidhiyo kadhi richatsigira tekinoroji yakafanana ne , yekuchengetera yakavimbika zvakanyanya yezvakakosha zvemukati - inonzi GPU SGX.
Takataura Intel Software Guard Extensions tekinoroji nguva pfupi yadarika maererano ne . Intel SGX yekuwedzera seti yeCPU mirairo inogonesa maapplication kugadzira enclaves, matunhu akadzivirirwa munzvimbo yekero yekushandisa iyo inopa kuvanzika uye kutendeseka kunyangwe pamberi peiyo yakasarudzika malware.
Asi haisi iyo chete kodhi kodhi inoda kuchengetedzwa, asiwo data yemushandisi. Mauto ematsotsi anorota siku nesikati nezve maitiro ekubira mafoto ako obva adzima kana encrypt. Sei kusasara usina ndangariro dzinonyanya kukosha? Intel SGX, mune yayo GPU SGX akasiyana, inogonawo kuuya kuzonunura pano. Munyaya iyi inoshanda sezvinotevera.
Basa rakakosha mune iyi tekinoroji, sekureva kunoita zita, inoridzwa neiyo graphics processor. "Kadhi revhidhiyo rinei nazvo kana zvasvika pakuchengeta data?" - zvichida unobvunza. Icho chokwadi ndechekuti neruremekedzo rwese rwakakodzera kuIntel SGX, pane kakawanda mashoma ma processors anotsigira tekinoroji iyi pane ayo asingaite. Naizvozvo, zvakasarudzwa kuendesa kuurayiwa kweSGX-inotsamira kodhi kuGPU, yakafanana nemaitirwo azvakaitwa muIntel SGX Card yakambotaurwa. Iyo vhidhiyo kadhi ine imwezve mukana: dhizaini yayo inobvumira kuti igare yakaringana yakawanda ye flash memory, iyo inogona kushandiswa seyenzvimbo yakachengetedzwa yekuchengetedza.
Iyo yekushandisa musimboti weGPU SGX ndeiyi inotevera. Mapikicha embwa yako yaunofarira, pamwe chete neimwe yakakosha data, inoiswa panzvimbo yekuchengetedza yekadhi revhidhiyo uchishandisa yakakosha Intel software. Intel SGX dziviriro inoshanda pane iyo faira system driver level. Tevere, iyo yakakosha software inowiriranisa zviri mukati mekuchengetedza neyegore sevhisi mune imwe yemamodhi akasarudzwa nevashandisi. Kusiyana nemamwe masevhisi egore, mutengi weIntel haagone kukanganisika nekuti inobata nzvimbo dzakasimba dzekodhi muSGX enclaves. Saka, data rako rinogashira akati wandei madhigirii edziviriro kubva pakuba uye kuparadza.
Chii chinoitika kana Intel software ikamira kushanda nekuda kwechimwe chikonzero uye iyo data yakavharwa chaizvo mukuchengetedza kwayo? Intel inotarisira kugovera tekinoroji yayo nevechitatu mapato zvichibva pane yakasimba certification uye kutonga. Saka pachava neimwe nzira. Zvakanaka, iyo system pachayo ichaonekwa pamusika kwete pamberi pekuonekwa kwemakadhi evhidhiyo ivo pachavo - iyo nguva ichiri isina kujeka. Asi isu tichamirira.
