Ikhadi Lokukhanya le-DESFire, Ihambisana ne-NFC Type Tag 4, I-DESFire Light Chip Card, I-DESFire Ikhadi Elimhlophe Elikhanyayo

I-MIFARE ye-NXP^® DESFIRE^® Ukukhanya kuyi-IC engathinteki eyenzelwe ukuhlanganiswa kalula kumasistimu amasha nakhona kakade. Ihlanganisa isistimu yefayela echazwe ngaphambilini kanye nengqikithi ye 640 amabhayithi enkumbulo etholakalayo (elilingana ne 1 KB ku-MIFARE^® Okwakudala^®), ikwenze kube ukukhetha okuhle kwemiklamo yohlelo lokusebenza olulodwa kumacala amaningi okusetshenziswa. Mina^® DESFIRE^® Ukukhanya kuhambisana ne-MIFARE DESFire EV2, okuvumela abaklami ukuthi banwebe kalula amasistimu abo ukuze basekele izinhlelo zokusebenza ezintsha. Iyahambisana ne-MIFARE DESFire^® I-EV2 iphinde ivumele abathuthukisi ukuthi bakhuthaze izinsizakalo zabo ku-NXP's AppXplorer, inkundla yokuhlanganyela edala umuzwa ofana ne-App Store kumakhadi ahlakaniphile. I-MIFARE DESFire Light nayo ingalungiswa njengohlobo lwe-NFC Forum ye-NFC 4 umgoga, ukuyenza ilungele ukusetshenziswa nezinhlobonhlobo zamadivayisi eselula ahlomeke ngamakhono okufunda ngaphandle kokuthinta. Idizayinelwe kokubili izinhlelo zokusebenza ezinomkhawulo nezinwetshiwe, I-NXP^® Mina^® DESFIRE^® Ukukhanya kufaka phakathi izindlela zokuvikela ezifanele zokuletha amasevisi athembekile. Kuye ngecala lokusebenzisa, kufika okhiye abayisihlanu be-AES 128-bit bangasetshenziswa ukuphatha amalungelo okufinyelela, kuyilapho izinketho zemiyalezo evikelekile zithuthukisa idatha nokuvikelwa kobumfihlo. Zonke izici ze-chip nezokuphepha zesoftware zibuyekezwe ngaphandle, ihlolwe, futhi kugunyazwe Imibandela Ejwayelekile EAL4.
