I-NXPIkhadi le-MIFARE desfire EV3 2K 4K 8K

I-NXP MIFARE DESFire EV3 imele isiqongo sobuchwepheshe bekhadi elihlakaniphile le-smart, elinikeza ukuvikeleka okungakaze kubonwe, ukuguquguquka, nokusebenza kwezinsizakalo zedolobha elihlakaniphile zesimanje kanye nezinhlelo zokusebenza zokulawula ukufinyelela. Atholakala ngezinhlobonhlobo zememori engu-2K, 4K, kanye ne-8K, lawa makhadi e-NFC aletha ukuvikeleka kwezinga lebhizinisi kalula nje ngokusebenza ngaphandle kokuthinta.

Uhlolojikelele Lomkhiqizo kanye Nezicaciso Zobuchwepheshe

Ikhadi le-MIFARE DESFire EV3 lisebenza ngo-13.56MHz futhi limele inguquko yakamuva emndenini odumile we-MIFARE DESFire we-NXP. Lawa makhadi afaka:

• Izinketho zememori: 2K, 4K, noma 8K bytes
• Ukubethela okuthuthukile: Ukusekelwa kwe-AES, i-DES, ne-3DES
• I-ISO/IEC 14443 Ukuthobela kuze kufike kungqimba 4
• Isivinini sokwenziwe: singafika ku-848 kbps
• Ukugcinwa kwedatha: iminyaka engama-25
• Bhala ukukhuthazela: 500,000 imijikelezo

Ihambisana nengqalasizinda ekhona, lawa makhadi e-RFID agcina ukuhambelana okubuyela emuva kuyilapho ethula izici zokuphepha ezithuthukisiwe.

Izici Zokuvikela Ezithuthukisiwe Nokubethela

Ukuvikeleka kumi emnyombweni womklamo we-MIFARE DESFire EV3. Ukwakhela phezu kwesisekelo esiqinile sabanduleli bayo (i-DESFire EV1 ne-EV2), i-EV3 iyasebenza:

• Umgomo Ojwayelekile we-EAL5+ isitifiketi
• Isici somlayezo Secure Unique NFC (SUN).
• Ukubethela kwe-AES okusekelwe ku-hardware
• Ukuhlola ukusondela ngokumelene nokuhlaselwa kwe-relay
• Ukuvikelwa kobumfihlo okuthuthukisiwe nge-UID engahleliwe

Ukuvikeleka kwekhadi nezici zobumfihlo zilenza lilungele izinhlelo zokusebenza zokuphepha okuphezulu ezidinga ukuvikelwa ekuhlaselweni okuyinkimbinkimbi.

Ukusekelwa Kwezicelo Eziningi Nokuvumelana nezimo

Esinye sezici ezinamandla kakhulu zesixazululo se-MIFARE DESFire EV3 yikhono layo lokusekela izinhlelo zokusebenza eziningi ngesikhathi esisodwa. Uhlelo lokusebenza ngalunye lungakwazi:

• Gcina okhiye bokuvikela abahlukene
• Sebenza ngokuzimela
• Dlulisa idatha ngokuphephile phakathi kwezinhlelo zokusebenza
• Sekela izakhiwo zefayela eziguquguqukayo

Lokhu kwenza lawa makhadi ahlakaniphile afaneleke ekusetshenzisweni okuyinkimbinkimbi lapho isitifiketi esisodwa sidinga ukufeza izinjongo eziningi.

Amacala Okusebenzisa Nokusebenzisa

Amakhadi e-EV3 ahamba phambili ezinhlelweni ezihlukahlukene:

• Izinhlelo zokukhokha zokuhamba zomphakathi
• Ukuqinisekisa kokulawula ukufinyelela
• Ukuhlanganiswa kwezinsiza zedolobha elihlakaniphile
• Izixazululo zamakhadi ekhampasi
• Izinhlelo zokwethembeka
• Amathikithi e-elekthronikhi

Izinhlangano zingasebenzisa lawa makhadi ukuze zithuthukise ingqalasizinda yazo yezokuphepha kuyilapho zithuthukisa ulwazi lwabasebenzisi ngokusebenza ngaphandle kokuthinta.

Ukukhiqiza Nokuqinisekisa Ikhwalithi

Amakhadi ethu e-EV3 abhekana nezinqubo eziqinile zokulawula ikhwalithi:

• Ukwakhiwa kwe-PVC ukuze kuqine
• Indawo ephrintekayo yokudlulisa okushisayo
• Ukushumeka kwe-IC kusetshenziswa amasu athuthukile
• Ukuhlola okungu-100% ngaphambi kokuthunyelwa
• Itholakala ngephakethe lama-100 noma amanani angokwezifiso

Ikhadi ngalinye liza ne-UID eyingqayizivele futhi lilungele ukuthunyelwa ngokushesha kusistimu yakho.

Uku-oda kanye nolwazi lokusekela

Sinikeza ukwesekwa okuphelele kwemikhiqizo yethu ye-MIFARE DESFire EV3:

• Amadokhumenti obuchwepheshe
• Isiqondiso sokuqalisa
• Izaphulelo ze-oda lenqwaba
• Izinketho zokuthumela emhlabeni wonke
• Usizo lokuhlanganisa lomuntu wesithathu

“I-MIFARE DESFire EV3 imele ikusasa lemisebenzi evikelekile yokungathinteki. Izici zayo ezithuthukile nokuvikeleka okuqinile kuyenza ibe inketho efanelekile ezinhlelweni zesimanje zedolobha elihlakaniphile.” - Isazi Sokuphepha se-NXP

Ukusekela Kwekhasimende kanye Nemibhalo

Ithimba lethu losekelo elizinikele lihlinzeka:

• Amadokhumenti omkhiqizo anemininingwane
• Imihlahlandlela yokusebenzisa
• Ukubonisana kwezobuchwepheshe
• Ukwesekwa ngemuva kokuthengisa
• Ukuthuthukiswa kwesixazululo ngokwezifiso

Ukuze uthole ulwazi lwamanani kanye nokuthumela umbuzo, sicela uxhumane nethimba lethu labadayisi noma ugcwalise ifomu lethu eliku-inthanethi. Sinikeza amanani okuncintisana kokubili ama-oda amancane namakhulu.
