I-Ultralight AES Chip Cards, Ultralight AES Chip Ihhotela Igumbi Keys, I-Ultralight AES Vingard Card, Amathikithi e-Ultralight AES Chip

I-MIFARE Ultralight AES iyikhadi le-smart IC elingabizi elingabizi kakhulu elethulwe yi-NXP, yakhelwe ukusetshenziswa okulinganiselwe amacala (njengamathikithi ezokuthutha nokulawula ukufinyelela ehhotela). Ifaka ukubethela kwe-AES-128 kanye nezindlela zokuphepha ezithuthukisiwe, futhi inezici ezilandelayo:
Mina. Izici Zokuvikela
Ukuqinisekisa Ukubethela kwe-AES-128: Isekela ukuqinisekiswa kwezinyathelo ezimbili kwezinyathelo ezintathu, ikhiqiza ngokuguqukayo okhiye besikhathi, futhi ivimbela ukufinyelela okungagunyaziwe.
Ukuvikela Ukuqinisekisa Okubi: Ikhawunta ye-24-bit yendlela eyodwa kanye nesibali sokuyala sikhawulela inani lemizamo yokuqinisekisa engavumelekile.
Ukuvikelwa Kobuqotho Bedatha: Iqinisekisa imilayezo yokuxhumana nge-CMAC (I-MAC esekwe kuCipher) ukuvimbela ukuphazamisa.
Ukukhiya ukhiye: Isekela indlela yokugcina ukhiye we-AES evikelwe ngokubhala, iyahambisana nokhiye bendabuko be-CRYPTO1.
II. Ukusebenza Nokuhambisana
Umthamo wokugcina: 144 amabhayithi enkumbulo yomsebenzisi we-EEPROM, isekela 100,000 bhala imisebenzi ngomjikelezo ngamunye.
Iphrothokholi Yokuxhumana: Ihambisana ne-ISO/IEC 14443 I-A-2/-3 ejwayelekile, imvamisa yokusebenza 13.56mhz, izinga lokudlulisela 106 kbit / s, ibanga lokufunda lifika ku-10cm.
Ukuhambisana: Isakhiwo sememori siyefana nochungechunge lwesizukulwane esedlule se-MIFARE Ultralight, lula ukuthuthukiswa kwesistimu.
Isekela ama-ID angahleliwe nama-UID angu-7-byte ukuze kuvikelwe ubumfihlo obuthuthukisiwe.
III. Izimo Zokusebenza
Amathikithi Ezokuthutha: Ishintsha amathikithi ephepha/amakhodi e-QR, isekela amathikithi ohambo olulodwa, amathikithi ohambo oluningi, namathikithi omcimbi
Ukulawula Ukufinyelela Ehhotela: Ihlanganiswe nohlelo lokukhiya i-Assa Abloy Vingard, ukuhlinzeka ngokungena okuvikelekile emakamelweni ezivakashi nasezikhungweni.
Amakhadi Obulungu/Izinkokhelo Zenani Elincane: Ifanele izindleko eziphansi, ukuvikeleka okuphezulu, izimo zokusetshenziswa okulinganiselwe.
