DESFire 8K EV3 Cards for High Secure Identity
Amakhadi e-MIFARE DESFire EV3 8K RFID ngamakhadi aphucukileyo angenanxibelelwano abonelela ngokhuseleko olomeleziweyo kunye nokuguquguquka kwezicelo ezahlukeneyo. I-8KB EEPROM ivumela izicelo ezininzi kunye neefayile (ukuya kwiifayile ze-32 ngesicelo ngasinye). Iikhrayitheriya eziqhelekileyo eziqinisekisiweyo ze-EAL5 +, amakhadi e-Desfire 8K EV3 ane-encryption ye-AES-128 kunye nokuqinisekiswa okufanayo ukukhusela idatha ebuthathaka. Kwaye amakhadi abuyele umva ngokupheleleyo ahambelana nezizukulwana zangaphambili ze-MIFARE DESFire (EV1, EV2), ukuqinisekisa ukudibanisa lula kwiinkqubo ezikhoyo.

Ingaba ikhadi le-DESFire EV3 8K lizisingatha njani izicelo ezininzi?
Ikhadi isebenzisa umbutho we-hierarchical apho izicelo zenziwe kwaye zilawulwa kwisakhiwo esinengqiqo. Isicelo ngasinye sinokubandakanya iifayile ezininzi ezinokufikelela-kulawulwa ngokuzimeleyo.
Isicelo ngasinye esisekhadini sichongwe ngokukodwa sisiSazi seSicelo (AID), sivumela inkqubo ukuba iqaphele kwaye ilawule izicelo ezininzi ngokufanelekileyo.
Ikhadi le-DESFire EV3 8K linomthamo wememori obalulekileyo (i-8K bytes) enokwahlulwa phakathi kwezicelo ezininzi. Isicelo ngasinye sinokuba nesithuba saso sokugcina esabelwe iifayile kunye nedatha.
I-DESFire EV3 ixhasa izitshixo ezininzi ngesicelo ngasinye, ivumela amanqanaba ahlukeneyo olawulo lokufikelela kunye nokuqinisekisa ukuba idatha ebuthathaka ikhuselwe.
Ikhadi le-DESFire EV3 lisebenzisa i-protocol yonxibelelwano olukhawulezayo, evumela ukufikelela ngokukhawuleza kwizicelo ezahlukeneyo ngaphandle kokulibaziseka okubalulekileyo, okubalulekileyo kwiindawo ezifana nolawulo lokufikelela kunye neenkqubo zokuhlawula apho isantya sibalulekile.
Ikhadi le-DESFire EV3 lixhasa ukuqinisekiswa okufanayo ukuqinisekisa ukuba zombini ikhadi kunye nomfundi ziqinisekisana phambi kokuba naluphi na usetyenziso lwesicelo, luthintela ukufikelela okungagunyaziswanga.
Abalawuli banokongeza, bacime, okanye balungise usetyenziso kunye nezicwangciso zabo ekhadini, bevumela uhlaziyo olulula njengoko iimfuno zombutho ziguquka.
