Ikarita ya Mifare 1k niyihe?

MIFAre Classic 1K Ikarita yakubiswe nikarita ya M1, ni ikarita idahuza na radiyo. Ikoranabuhanga ryo kuvugana nikarita ya radiyo yitwa Ikoranabuhanga ryitumanaho ryumurimo, cyangwa NFC kubwaho.

Ikarita ya M1 igabanyijemo ibice 16, buri murenge uhuye na 4 (guhagarika 0-guhagarika 3), hamwe na 64 hamwe na 64, bagera kuri 64, bagera kuri 64. Kuzenguruka 0 kwumurenge wa 0 ikoreshwa muguka kode yuwabikoze, irakomeye ntishobora guhinduka. Guhagarika abantu 0-2 bya bisigaye bikoreshwa mubika amakuru, kandi guhagarika 3 ni uguhagarika bikoreshwa mu kubika ijambo ryibanga a, kugenzura, hamwe nijambobanga B. Imiterere ni iyicwa:

A0 A1 A2 A3 A3 A3 A5 A5 FF 07 80 69 b0 b1 b3 b4 b5

(Ijambobanga 6 bytes) (kugenzura ububiko 4 bytes) (ijambo ryibanga b 6 bytes)

Byongeye kandi, ijambo ryibanga nubugenzuzi muri buri Murenge uhagarika 3 byose byigenga, kandi ibikorwa bitandukanye byumurenge bigenzurwa ryigenga. Buri murenge urashobora kumenya imirimo itandukanye, rero ikoreshwa cyane nkikarita.

Buri nkoni iri mukarita irimo 16 Bytes, bityo ubushobozi bwa M1=16 Imirenge ya 4 * 16 byAtes {16= 1 k (Inkomoko ya Ikarita ya M1).

Igice cya mbere cyinzego zambere cyikarita kibika usid idasanzwe. Abandi bafite uid kwemeza bits hamwe namakuru yabakora. Kubakarita bakoze ukurikije ibisobanuro, iki gice kizandikwa mu ruganda kandi gishobora gusomwa gusa kandi ntigishobora gusomwa. Andika. Birumvikana, hariho nikarita idasanzwe ya UID, UID irashobora guhinduka.

Imipaka ya Mifare 1K ikoreshwa cyane kubaturage kugenzurwa n'abaturage, gucunga abakozi, ikarita ndangamuntu, ikarita ya terefone igendanwa.
