Amagama Ayimfihlo, Khiya Ubumbudumbudu kanye Nemikhawulo Engafinyeleli Eshidini Elicacisiwe
Izingqinamba ezine kulo mndeni zibhaliwe kodwa azivamile ukuvela ngesikhathi sokukhethwa, futhi ngayinye ivale idizayini ngemva kokusayinwa kwe-oda lokuthenga.
Esokuqala siphathelene nokuvikelwa. Zontathu izingxenye zinikela ngephasiwedi engu-32-no-16-okuvuma kancane, futhi igama elithi "iphasiwedi" lenza umsebenzi omningi ongakaziwa ezincwadini zabahlinzeki. Inani lidluliselwa ngokucacile futhi lihlolwe yi-chip, ukufinyelela kokubhala kwesango kanye nokufinyelela kokufunda ngokuzithandela ekhasini oliqokile. Lokho kumisa ilungu lomphakathi ukuthi libhale kabusha umaka obheke emphakathini ngefoni, okuyinto yangempela newusizo. Akukona ukulawulwa kwe-cryptographic, akumelani nomhlaseli ozimisele, futhi akufanele neze kuvele kudokhumenti ecacisiwe eduze kwegama elithi "vikela". Izicelo ezenza isimangalo sobuqiniso kukhasimende lokugcina zidinga ingxenye esekelwe ku-AES, hhayi ukuvikelwa kwephasiwedi ye-NTAG215 enencazelo enethemba enamathiselwe.
Okwesibili, futhi lokhu kuveza umphumela-ohlakaniphile kakhulu emndenini, kuza ubumbudumbudu besikhiya. Ukukhiya lawa mashiphu akuyona iswishi eyodwa. Amabhayithi amathathu okukhiya ashintshashintshayo amboza ucezu oluchaziwe lwendawo yedatha, futhi isifunda esincane kunazo zonke isilawuli sebhithi ngasinye sihluka ngokwengxenye: amakhasi amabili ku-chip 144-yebhayithi, amakhasi ayishumi nesithupha kulawa amabili amakhulu. Amakhasi ayishumi nesithupha angamabhayithi angamashumi ayisithupha{8}}angamashumi ayisithupha nane. Ngakho-ke isakhiwo esixubile ku-NTAG215, esinesifunda esiqandisiwe efekthri kanye nesifunda somkhankaso esishiywe sibhaleka, siyasebenza kodwa simaholoholo, futhi umngcele ophakathi kwakho kokubili kufanele uhlale kulayini{9}}ongamabhayithi amane. Idizayini edinga inkambu encane ekhiyiwe eseduze nenkambu encane ebhalekayo ilula ku-chip encane, ephambene ngokuqondile nalokho abathengi abakulindele lapho benyukela phezulu ukuze babe nezimo.
Ukuzijwayeza kwemboni kunikeza isivimbelo sesithathu, futhi kuyinqubo esikhundleni sezobuchwepheshe. Inothi lohlelo lokusebenza olukhomba ishidi ledatha ukuze kusetshenziswe kahle lezo zingxenye zokukhiya akuyona idokhumenti yomphakathi; kudinga isivumelwano nomkhiqizi kanye nokufinyelela esitolo sabo semibhalo ekhawulelwe, umkhawulo oqinisekiswa onjiniyela babo kuforamu yabathengisi (Umphakathi we-NXP). Ukuthi ukukhiya kungenziwa ngendlela efanele eqeqebeni lakho ngakho-ke ngokwengxenye kuwumbuzo mayelana nesiteshi somphakeli wakho, hhayi nge-silicon kuphela. Kufanelekile ukubuza ngaphambi kwe-oda kunokuthi emva kwalokho.
Eyesine ikhiqiza i-inventory elahliwe kunomklamo ovinjiwe. Ukuvikela{1}}okudabuka ku-NTAG21x, okuchazwe kunothi lohlelo lokusebenza lomkhiqizi siqu AN13089, lufaka indawo ye-OTP, izingidi zokukhiya nezinto zokubala. Ayifaki amakhasi edatha yomsebenzisi. Uma ithegi ishiya inkambu ye-RF idlula phakathi-nombhalo wenkumbulo yomsebenzisi, okuwumkhuba kulayini wokukhiqiza onyakazayo noma esandleni somqhubi we-warehouse osebenza ngokushesha, i-chip ayiqinisekisi lutho mayelana nalokho okusele. Ukuvikela idatha yomsebenzisi ekudabukeni-kuyisibopho{9}}sesendlalelo sohlelo lokusebenza, futhi noma iyiphi inqubo yombhalo wekhodi ebhala ngaphandle kokuyifunda iwunqabele buthule lowo mthwalo wemfanelo. Lesi ngesinye sezizathu zokuthi iphasi{11}}kumugqa wokuqinisekisa ayikhethi ngaphezu kwamayunithi ayizinkulungwane ezimbalwa.
Ukufakazela Iqoqo Ngempela Liqukethe Ama-Chips Angempela E-NTAG215
Leli izinga labathengi abangcupheni eliphansi kakhulu futhi kufanele baklelise isibili. Ithegi efundeka kahle ocingweni ayikutsheli cishe lutho mayelana nokuthi iyiphi i-silicon engaphakathi, futhi ukushintshwa kwalesi sigaba kubhalwe phansi esikhundleni sokucatshangelwa: onjiniyela abathenge izinhlobonhlobo zamathegi e-NTAG21x ngamashaneli ajwayelekile okuthengisa abikwe emphakathini womkhiqizi ukuthi isampula ngalinye liziphathe ngendlela ecaciswayo, kufakwe nesibuko esiphikisayo, kuyilapho ukuhlola kokwangempela kubuyise izingxenye ezingaqinisekisiwe njengesignesha ye-silicon. Impendulo eshicilelwe yomkhiqizi ibiwukuthi imikhiqizo enjalo ayisekelwe futhi akufanele kuthenjelwe kuyo ukuze isetshenziswe ngokuphephile, ngoba i-IC ngokwayo ingase ibe sengozini (Umphakathi we-NXP).
Amasheke amathathu enza inqubo engenayo esebenzayo, futhi asebenza cishe iminithi ngesampula ngayinye.
Qala ngempendulo yenguqulo. I-chip izobika usayizi wayo wesitoreji, kodwa ibika njengobubanzi kunevelu: ingxenye engu-144-yebhayithi iwela phakathi kuka-128 no-256, ingxenye engu-504-byte phakathi kuka-256 no-512, ingxenye engu-888-byte phakathi kuka-512 no-1024. Ngakho-ke, ukufunda okukodwa kufinyeza i-ident eyodwa, ngakho-ke ukucaciswa kwayo kufinyeza ngokuqhathanisa ne-identified kanye nempendulo itafula lokubheka.
