MIFARE Plus Family

Umndeni womkhiqizo we-MIFARE Plus® uklanyelwe ukuba ube womabili, isango lezicelo ezintsha ze-Smart City kanye nokuthuthukiswa kokuphepha okuphoqelelayo kwengqalasizinda yefa. Inikeza inzuzo yokuthuthukiswa okungenazihibe kokufakwayo okusekelwe kumkhiqizo okukhona kakade kwe-MIFARE Classic® namasevisi ngomzamo omncane. Lokhu kuphumela ethubeni lokukhishwa kwamakhadi, ukuhlehlela emuva ngokugcwele ku-MIFARE Classic, ezindaweni ezikhona zesistimu ngaphambi kokuthuthukiswa kokuphepha kwengqalasizinda. Ngemuva kokuthuthukiswa kwezokuphepha, imikhiqizo ye-MIFARE Plus isebenzisa ukuphepha kwe-AES ukuze kuqinisekiswe, ubuqotho bedatha kanye nokubethela okusekelwe ezimisweni ezivulekile, zomhlaba jikelele.

I-MIFARE Plus EV2

Njengesizukulwane esilandelayo somndeni womkhiqizo we-MIFARE Plus we-NXP, i-MIFARE Plus® EV2 IC yakhelwe ukuthi ibe yisango lezinhlelo zokusebenza ezintsha ze-Smart City kanye nokuthuthukiswa okuphoqelelayo, mayelana nokuphepha nokuxhumana, kokuphakelwa okukhona.

Umqondo omusha Wezinga Lokuphepha (SL), kanye nesici esikhethekile se-SL1SL3MixMode, kuvumela izinsizakalo ze-Smart City ukuthi zisuke ku-algorithm yokubethela ye-Crypto1 eyifa ziye ekuvikelweni kwezinga elilandelayo. Izici ezikhethekile, njenge-Transaction Timer noma i-Transaction MAC ekhiqizwa ikhadi, zibhekana nesidingo sokuvikeleka okuthuthukisiwe nobumfihlo kumasevisi e-Smart City.

Ukusebenzisa i-MIFARE Plus EV2 Kusendlalelo Sezokuphepha 3 kusekela ukusetshenziswa kwesevisi yefu ye-MIFARE 2GO ye-NXP, ukuze izinsizakalo ze-Smart City ezifana namathikithi okuthutha amaselula nokufinyelela kweselula, zisebenze kuma-smartphones anikwe amandla yi-NFC nezinto ezigqokwayo.
