Ultralight AES Amakhadi Chip, I-Ultralight ye-AES Chip yeGumbi leHotele izitshixo, Ultralight AES Vingard Card, Ultralight AES Chip Amatikiti

I-MIFARE Ultralight AES yikhadi le-IC elingabizi kakhulu ngaphandle koqhagamshelwano elisungulwe yi-NXP, yenzelwe iimeko zokusebenzisa umda (ezifana namatikiti ezothutho kunye nolawulo lokufikelela ehotele). Ifaka i-AES-128 encryption kunye neendlela zokhuseleko eziphuculweyo, kwaye inezi mpawu zilandelayo:
I. Iimpawu zoKhuseleko
I-AES-128 yoQinisekiso oluFihliweyo: Ixhasa uqinisekiso lweendlela ezimbini ezithathu, yenza izitshixo zeseshoni ngamandla, kwaye ithintela ukufikelela okungagunyaziswanga.
Ukukhuselwa kweNgcaciso engalunganga: Ukhetho lwe-24-bit yendlela enye counter kunye nomyalelo wokubala umda inani lokuzama ukuqinisekiswa okungasebenziyo.
Ukhuseleko lweMfezeko yeDatha: Iqinisekisa imiyalezo yonxibelelwano nge-CMAC (Cipher-based MAC) ukuthintela ukuphazamiseka.
Ukutshixa isitshixo: Ixhasa indlela yokugcina i-AES ebhaliweyo ekhuselweyo, iyahambelana nezitshixo zemveli ze-CRYPTO1.
II. Ukusebenza kunye nokuhambelana
Umthamo wokuGcina: 144 iibhayithi zememori yomsebenzisi ye-EEPROM, ixhasa 100,000 bhala imisebenzi kumjikelo ngamnye.
IProtokholi yoNxibelelwano: Iyahambelana ne-ISO/IEC 14443 A-2/-3 umgangatho, Ukusebenza rhoqo 13.56mhz, izinga losulelo 106 kbit / s, funda umgama ukuya kwi-10cm.
Ukuhambelana: Isakhiwo sememori siyafana nesizukulwana sangaphambili se-MIFARE Ultralight series, ukuququzelela ukuphuculwa kwenkqubo.
Ixhasa ii-ID ezingaqhelekanga kunye nee-UID ze-7-byte zokhuseleko lwabucala oluphuculweyo.
III. Imeko yesicelo
Amatikiti ezothutho: Ithatha indawo yamatikiti ephepha/iikhowudi zeQR, ixhasa amatikiti ohambo olunye, amatikiti ohambo oluninzi, kunye namatikiti esiganeko
Ulawulo lokuFikelela kwiHotele: Idibanisa kunye nenkqubo yokutshixa i-Assa Abloy Vingard, ukubonelela ngolawulo lofikelelo olukhuselekileyo kumagumbi eendwendwe kunye nezibonelelo.
Amakhadi obulungu/Iintlawulo-mali encinci: Ifanelekile ngexabiso eliphantsi, ukhuseleko oluphezulu, iimeko zokusebenzisa umda.
