Ultralight AES Chip Cards, Ultralight AES Chip Hotel Room Keys, Ultralight AES Vingard Card, Matikiti a Ultralight AES Chip

MIFARE Ultralight AES ndi khadi ya IC yotsika mtengo yolumikizirana yokhazikitsidwa ndi NXP, opangidwa kuti azingogwiritsa ntchito zochepa (monga matikiti amayendedwe ndi njira zolowera kuhotelo). Imakhala ndi encryption ya AES-128 komanso njira zowonjezera chitetezo, ndipo ali ndi makhalidwe awa:
Ine. Zotetezera
Chitsimikizo cha AES-128 Encryption: Imathandizira kutsimikizika kwa magawo atatu, imapanga makiyi amgawo mwachangu, ndikuletsa kulowa kosaloledwa.
Chitetezo Chachidziwitso Choyipa: Mukasankha 24-bit ya njira imodzi ndi kauntala kulamula kuchepetsa chiwerengero cha zoyesera zosayenera.
Chitetezo cha Data Integrity: Imatsimikizira mauthenga olankhulana kudzera pa CMAC (Cipher-based MAC) kuteteza kusokoneza.
Kutseka Kwakiyi: Imathandizira makina osungira otetezedwa a AES, yogwirizana ndi makiyi achikhalidwe a CRYPTO1.
II. Magwiridwe ndi Kugwirizana
Kusunga Kutha: 144 ma byte a kukumbukira kwa ogwiritsa ntchito EEPROM, amathandiza 100,000 lembani ntchito pa kuzungulira.
Communication Protocol: Zogwirizana ndi ISO/IEC 14443 A-2/-3 muyezo, Kugwiritsa ntchito pafupipafupi 13.56mhz, kufala 106 kbit/s, werengani mtunda mpaka 10cm.
Kufanizika: Kapangidwe ka Memory ndi kofanana ndi m'badwo wakale wa MIFARE Ultralight, kupititsa patsogolo ndondomeko.
Imathandizira ma ID mwachisawawa ndi ma UID a 7-byte kuti apititse patsogolo chitetezo chachinsinsi.
III. Zochitika za Ntchito
Matikiti Amayendedwe: Imalowetsa matikiti apepala/makhodi a QR, imathandizira matikiti aulendo umodzi, matikiti amaulendo ambiri, ndi matikiti a zochitika
Hotel Access Control: Zimaphatikizana ndi Assa Abloy Vingard loko system, kupereka chitetezo cholowera m'zipinda za alendo ndi malo.
Makhadi Amembala / Malipiro Aang'ono: Zoyenera zotsika mtengo, chitetezo chapamwamba, zogwiritsa ntchito zochepa.
