Mifare 1K Card kye ki?

Mifare Classic 1K Card efunzibwa nga M1 card, nga eno ye kaadi ya leediyo etali-ekwatagana. Tekinologiya w’okuwuliziganya ne kaadi ya leediyo eyitibwa Near Field Communication Technology, oba NFC mu bufunze.

Kaadi ya M1 egabanyizibwamu ebitundu 16, buli kitundu kikwatagana ne bbulooka 4 (block 0-block 3), omugatte gwa bbulooka 64, ennamba 0-63. Bbulooka ya 0th eya 0th sector ekozesebwa okutereka code y’omukozi, ebadde ekakasiddwa tesobola kukyusibwa. Bbulooka 0-2 ez’ebitundu ebisigadde zikozesebwa okutereka data, ate Block 3 ye control block ekozesebwa okutereka password A, okuyingira okufuga, ne password B. Enzimba eri bweti:

A0 A1 A2 A3 A4 A5 ff 07 80 69 B0 B1 B2 B3 B4 B5 .

(Ekigambo ky’okuyingira A 6 bytes) (Okufuga okutereka 4 bytes) (ekigambo ky’okuyingira B 6 bytes) .

Ekirala, okufuga ebigambo by’okuyingira n’okutereka mu buli bbulooka y’ekitundu 3 byonna byetongodde, era emirimu egy’enjawulo egy’ekitundu gifugibwa mu ngeri eyeetongodde. Buli kitundu kisobola okutegeera emirimu egy’enjawulo, kale kikozesebwa nnyo nga kaadi.

Buli bulooka mu kaadi erimu bytes 16, kale obusobozi bwa kaadi ya M1=16 ebitundu * bulooka 4 * bytes 16=1024 bytes=1k (ensibuko ya kaadi ya M1).

Ekitundu ekisooka mu kitundu ekisooka ekya kaadi kitereka UID ey’enjawulo mu nsi yonna. Abalala balina UID validation bits n'amawulire agakwata ku bakola. Ku kaadi ezikolebwa okusinziira ku bikwata ku nsonga, ekitundu kino kijja kuwandiikibwa-okukuumibwa mu kkolero era kisobola okusomebwa kyokka era tekisobola kusomebwa. Wandiika. Kya lwatu, waliwo ne kaadi ya UID ey’enjawulo, UID esobola okukyusibwa.

Mifare 1K Card ekozesebwa nnyo mu kufuga okuyingira kw’abantu, okuddukanya abakozi, kaadi y’okuzuula, kaadi y’essimu ey’omu ngalo.
