NTAG ngokwezifiso 413 DNA/424 DNA Isitika, Ukumelana Nedatha Ye-Tamper, Ukuvikeleka Okuphezulu Nobumfihlo

Ingaphinda inikeze ngamasevisi enziwe ngendlela oyifisayo ukuhlangabezana nemibono nezidingo zakho ezikhethekile 413 I-DNA iguqula iphothifoliyo yomkhiqizo we-NTAG ngokuletha ubuqiniso be-AES Cryptographic futhi ivumela ngokuzenzakalelayo nangokuphepha kwinsizakalo yewebhu ngokuthepha nje i-Tag ngaphandle kwesidingo sohlelo lokusebenza olunikezelwe kwi-NFC.
Ngaphandle kwesiginesha ye-NXP Filation kanye nokuqinisekiswa okulandelayo okungu-3, yethula isici sokuphepha kwenoveli esibizwa nge- "evikelekile eyingqayizivele ye-NFC (Ilanga)”, okukhiqizwa ngokuzenzakalelayo idatha yokufakazelwa kokuthenjwa kwethempeli nge-Tap-Unique Kukunye okufundwayo okunikezela ukuxhumana okuzinikele okukhethekile kumsebenzisi ngamunye ngokusekelwe kwimibandela echazwe ngaphambilini. Alukho uhlelo lokusebenza (Kudivayisi ye-NFC) kuyadingeka ukukhiqiza le datha ehlukile kampompi okubandakanya imininingwane ekhethiwe ethathwe ku-chip uid, I-tap counter futhi iqukethe idatha. Idivaysi enikwe amandla i-NFC ingaxhuma ngokuzenzakalelayo kwisevisi esekwe kwiwebhu futhi isuselwa kulwazi oluqukethwe ku-URL, Idivayisi ingabheka ubuqiniso bethegi bese iqinisekisa ubuqiniso bolwazi. Ingaphinda inikeze ngamasevisi enziwe ngendlela oyifisayo ukuhlangabezana nemibono nezidingo zakho ezikhethekile 413 I-DNA inikezela ukuguquguquka kokwakheka kwale setha ledatha eyingqayizivele.
Ingaphinda inikeze ngamasevisi enziwe ngendlela oyifisayo ukuhlangabezana nemibono nezidingo zakho ezikhethekile 413 I-DNA iyikhambi elifanelekile lokuzibandakanya nabathengi ngokuqukethwe okunamandla okuqukethwe kwe-Expe Riences, kubangelwa ngokuphelele yibo futhi kwasebenza ngesikhathi sangempela. Ngalokho inika amandla amamaki ahlakaniphile asuselwa kumathuba okubandakanya abathengi abasebenza ngokuqhubekayo ngendlela ephephile. Izicelo zifaka kepha azikhawulwanga ekuzibandakanyeni kwabathengi, ukuvikelwa komkhiqizo, ukulawula ukufinyelela, izaphulelo zesikhathi esisodwa kanye namacala afanayo okusetshenziswa lapho ubufakazi bokuhluka, Umsuka kanye nobukhona bethegi engokomzimba buyadingeka.
Ingaphinda inikeze ngamasevisi enziwe ngendlela oyifisayo ukuhlangabezana nemibono nezidingo zakho ezikhethekile 413 I-DNA iqinisekisiwe njengohlobo lwe-NFC Forum 4 I-Tag futhi ihambisana ne-ISO / IEC14443-4, Iso / IEC 7816-4 isakhiwo sefayela nefomethi ye-apdus. Ngenxa yokukhonkotha okuphezulu (70uhlobo), Ingaphinda inikeze ngamasevisi enziwe ngendlela oyifisayo ukuhlangabezana nemibono nezidingo zakho ezikhethekile 413 I-DNA Tag IC isetshenziselwa izinhlelo zokusebenza ezidinga izinyawo ezincane, Ngaphandle kokuyekethisa ekusebenzeni. Amathegi amancane we-NFC angafakwa kalula ku-e.g. Amalebula womkhiqizo noma amadivaysi kagesi. Ukucaciswa kwemishini kanye nogesi kwe-NTAG 413 I-DNA yenzelwe ukuhlangabezana nezidingo zomsebenzi we-inlay kanye nethegi.

Izici zokuphepha
Vikela umlayezo oyingqayizivele we-NFC (Ilanga)
Izinkinobho zohlelo lokusebenza ezintathu ze-AES 128-bit ezibandakanya izinhlobo eziphambili
Ikhawunta ye-NFC ekhuphukayo, okubalwa empompini ngayinye
I-AES esekelwe Dynamic CMAC njengengxenye yedatha ye-NDEF
Ukuqinisekiswa okuningana kokuphawula
-Gqamile, Ukuxhumana okwenziwe nge-Cmaced nokubhaliwe (-ngenacala)
Ukubuyiselwa okuphephile kwekhawunta yeNFC (ngokuzikhethela)
Isiginesha ye-ECC esekelwe kwe-NXP
I-tamper-imelana ne-hardware evikelekile
