Kaadị Chip Ultralight AES, Ultralight AES Chip ụlọ nkwari akụ igodo, Kaadị Vingard Ultralight AES, Tiketi Chip Ultralight AES

MIFARE Ultralight AES bụ kaadị smart IC na-enweghị kọntaktị na-efu ọnụ nke NXP bidoro, emebere maka oke ojiji (dị ka tiketi ụgbọ njem na njikwa ịnweta ụlọ oriri na ọṅụṅụ). Ọ nwere atụmatụ nzuzo AES-128 yana usoro nchekwa emelitere, ma nwee njirimara ndị a:
m. Atụmatụ nchekwa
Nyocha nzuzo AES-128: Na-akwado nyocha ụzọ abụọ ụzọ atọ, dynamically na-ewepụta igodo nnọkọ, ma gbochie ohere na-enweghị ikike.
Nchekwa nyocha na-adịghị mma: Nhọrọ 24-bit counter otu ụzọ na counter iwu na-amachi ọnụ ọgụgụ nke mbọ nyocha na-ezighi ezi..
Nchekwa iguzosi ike n'ezi ihe data: Na-enyocha ozi nzikọrịta ozi site na CMAC (MAC dabere na Cipher) iji gbochie imebi.
Mkpọchi igodo: Na-akwado usoro nchekwa igodo AES echekwara ederede, dakọtara na igodo CRYPTO1 ọdịnala.
II. Arụmọrụ na ndakọrịta
nchekwa ikike: 144 bytes nke EEPROM ebe nchekwa, na-akwado 100,000 dee arụmọrụ kwa okirikiri.
Communication Protocol: Dabara na ISO/IEC 14443 A-2/-3 ọkọlọtọ, na-arụ ọrụ ugboro 13.56mhz, nnyefe ọnụego 106 kbit / s, agụ ihe ruru 10cm.
Ndakọrịta: Nhazi ebe nchekwa bụ otu usoro usoro MIFARE Ultralight ọgbọ gara aga, na-akwalite usoro nkwalite.
Na-akwado NJ na-enweghị usoro na 7-byte UID maka nchedo nzuzo emelitere.
III. Ihe ngosi ngwa
Tiketi ụgbọ njem: Dochie tiketi akwụkwọ / koodu QR, na-akwado tiketi otu njem, tiketi ọtụtụ njem, na tiketi mmemme
Njikwa nnweta ụlọ oriri na ọṅụṅụ: Na-ejikọta ya na sistemụ mkpọchi Assa Abloy Vingard, na-enye njikwa ohere nchekwa na ụlọ ndị ọbịa na akụrụngwa.
Kaadị otu/ụgwọ obere ego: Kwesịrị ekwesị maka ọnụ ala dị ala, elu-nchekwa, ọnọdụ eji kpachapụrụ anya.
