Ikhadi le-Mifare | I-NXP MIFARE DESFire® EV1 2k

Ikhadi le-MIFARE DESFire EV1 2K(D21), umkhiqizo wezinga eliphezulu kumakhadi angathintwa, lisebenza kumafrikhwensi angenantambo angu-13.56 MHz. Ilandela indinganiso ye-ISO 14443A ngenkathi iphrothokholi yayo yezokuthutha ihambisana nezinkambiso ze-ISO 14443-4.

Iqhayisa ngememori engaguquguquki engu-2K byte (NVM), ifakwe iphrosesa yedatha yokubethela kathathu ye-DES enesivinini esikhulu. Leli khadi liphinde liziqhenye ngohlaka lwalo lwenhlangano yememori eguquguqukayo kanye nendlela yokuqinisekisa ehamba phambili embonini, ne-mutual 3-pass. Kanye nejeneretha yenombolo engahleliwe eyingqayizivele kanye nethuluzi elikhethekile lokunqanda izinyembezi ukuze kuqinisekiswe ukuphepha kwedatha ngesikhathi sokuthenga okungenantambo, ikhadi le-MIFARE DESFire EV1 liza nebanga lokufunda elicishe libe ngu-10cm, kuye ngamandla anikezwa ngumfundi.

Idizayinelwe ngokuyinhloko ukuhlinzeka ngezixazululo ezivikelekile zokungathinteki kumasevisi ezokuthutha nezinhlelo ezihambisanayo zokwethembeka,

ikhadi le-MIFARE DESFire EV1 lingachaza kabusha indlela ophatha ngayo idatha.

Nazi izici ezintathu ezengeziwe ezenza ikhadi le-MIFARE DESFire EV1 ligqame:

1.Izinga Lokubethela Okuphakeme: I-co-processor yokubethela kwedatha ephindwe kathathu ye-DES iqinisekisa ukuvikeleka okukhulu kwedatha, iyenze ilungele ukusebenza okubucayi.

2.Ibanga Lokufunda Eliguquguqukayo: Ngokuya ngamandla anikezwe ngumfundi, ikhadi lisebenza ebangeni elimangalisayo elingafika ku-10cm, linikeza ukuguquguquka kwezinhlelo zokusebenza ezihlukahlukene.

3.Ubuqotho Bedatha Okuthuthukisiwe: Ngomshini ohlukile wokunqanda izinyembezi, ithembisa ubuqotho obuqinile bedatha ngisho nangesikhathi sokuthenga ngaphandle kokuthinta, iqinisekisa ukuphathwa kwedatha okuthembekile nokuvikelekile.

I-MIFAREDESFIRE

Ngokusekelwe kumazinga omhlaba avulekile kukho kokubili isixhumi esibonakalayo se-RF nezindlela zokubhala, umndeni wethu womkhiqizo we-MIFARE DESFire uhlinzeka ngama-IC asekelwe ku-microcontroller avikeleke kakhulu. Igama layo i-DESFire libhekisela ekusetshenzisweni kwezinjini ze-cryptographic ze-DES, 2K3DES, 3K3DES, kanye ne-AES hardware ukuze kutholakale idatha yokudlulisela.Lo mndeni ubafanele kakhulu abathuthukisi bezixazululo nabaqhubi besistimu abakha izixazululo ezinokwethenjelwa, ezisebenzisanayo, nezingathintekiyo. Imikhiqizo ye-MIFARE DESFire ingahlanganiswa ngaphandle komthungo ezinhlelweni zamaselula futhi isekele izixazululo zekhadi elihlakaniphile lezicelo eziningi ngobuwena, ukulawula ukufinyelela, ukwethembeka, kanye nezicelo zokukhokha okuncane, kanye nasekufakweni kwamathikithi ezokuthutha.
