I-Enclave evikelekile noma ukuphepha kwesigaba sokuqala kwama-Mac nama-iPhone avikela ekuhlaselweni kwezigebengu

Amadivayisi we-Apple ngokuvamile abhekwa njengavikeleke kakhulu. Ikakhulukazi uma sigxila, isibonelo, kuma-Mac noma ama-iPhone, noma ukuncintisana kwawo ngendlela yezinhlelo ze-Windows ne-Android. Imikhiqizo ye-Apple ayivamisile ukuhlangabezana nohlelo olungayilungele ikhompuyutha, ngokwesibonelo, futhi isivele ihlinzeka ngemisebenzi eyahlukene ukuvimbela amabhizinisi angagunyaziwe ukuthi angalandeleli. Iphrosesa ebizwa ngokuthi i-Secure Enclave nayo inesabelo esikhulu uma kuqhathaniswa nokuphepha kukonke kwalezi zingcezu. Uma ungumlandeli we-Apple, uzwile ngakho. Empeleni ingeyani, itholakala kuphi futhi inesibopho sani?

I-Secure Enclave isebenza njengephrosesa ehlukile ehluke ngokuphelele kulo lonke uhlelo futhi inomongo kanye nenkumbulo yayo. Njengoba ihlukanisiwe kokunye, iletha ukuvikeleka okukhulu kakhulu ngakho-ke isetshenziselwa ukugcina idatha ebaluleke kakhulu. Kodwa ungakhohliswa - I-Secure Enclave ayisetshenziselwa ukugcina idatha yakho ngokuqondile ngakho-ke ayisebenzi njengediski ye-SSD, isibonelo. Kulokhu, le processor inqunyelwe inkumbulo encane ye-flash, ngenxa yalokho ngeke ikwazi ukugcina ngisho nezithombe ezimbalwa zekhwalithi enengqondo. Inikeza kuphela inkumbulo engu-4 MB.

Ukuvikela idatha ebucayi kakhulu

Ngokuphathelene nale chip, inkulumo evame kakhulu ukusetshenziswa kwayo kuhlanganiswe ne-Face ID kanye nobuchwepheshe be-Touch ID. Kodwa ngaphambi kokuba sifinyelele kulokho, kuyadingeka ukuchaza ngokuningiliziwe ukuthi lezi zindlela zokuqinisekisa ze-biometric zisebenza kanjani. Idatha (ngendlela ye-mathematical notation), esetshenziselwa ukuqhathanisa phakathi nokuqinisekiswa ngakunye okulandelayo, vele ibethelwe kahle futhi ayikwazi ukukhishwa ukubethela ngaphandle kwalokho okuthiwa ukhiye. Futhi yilo khiye oyingqayizivele ogcinwe ngaphakathi kwe-Secure Enclave processor, ngenxa yokuthi ihlukaniswe ngokuphelele nayo yonke idivayisi futhi ayikwazi ukufinyelelwa, kuphela kulezi zimo.

Nakuba idatha ngokwayo igcinwe ngaphandle kwe-Secure Enclave, esebenza kuphela ngokugcina ukhiye, isabethelwe kahle futhi yile processor kuphela engakwazi ukuyifinyelela. Kunjalo, futhi awabiwe noma agcinwe ku-iCloud yomsebenzisi we-Apple noma amaseva we-Apple. Akekho ovela ngaphandle ongafinyelela kuzo, ngomqondo ongokomfanekiso.

I-Secure Enclave processor manje isithathwa njengengxenye ebalulekile yemikhiqizo ye-Apple. Mayelana nalokhu, i-Apple iphinde izuze ekusebenzelaneni okuhle kakhulu phakathi kwehadiwe nesoftware. Njengoba enakho ngokoqobo yonke into ngaphansi kwesithupha sakhe, uyakwazi ukulungisa imikhiqizo yakhe ukuze ihambisane nayo futhi anikeze izinzuzo esimane singahlangani nazo nabanye abakhiqizi. I-Secure Enclave ngaleyo ndlela ivikela amadivayisi e-Apple ekuhlaselweni abantu bangaphandle kanye nokwebiwa okungenzeka kwedatha ebucayi. Kungenxa yale ngxenye ukuthi akunakwenzeka ukuvula i-Touch ID kanye nokuphepha kwe-Face ID ukude, okuyiqiniso okungasetshenziselwa ukuvula ifoni kuphela, kodwa futhi kungakhiya idatha, izinhlelo zokusebenza nokunye.

Ukweqisa okuvamile kwegama elithi "umdondoshiya" kwathathelwa indawo igama elithi "akunjalo neze" 😅

Futhi futhi inqwaba yamaphutha ohlelo (okungajwayelekile neze kule seva)
