DESFire 8K EV3 Daim Npav rau Kev Ruaj Ntseg Siab
MIFARE DESFire EV3 8K RFID phaib yog cov ntawv tsis muaj kev sib txuas lus ntse uas muaj kev ruaj ntseg thiab yooj yim rau ntau yam kev siv. 8KB EEPROM tso cai rau ntau daim ntawv thov thiab cov ntaub ntawv (txog 32 cov ntaub ntawv ib daim ntawv thov). Cov Kev Cai Lij Choj EAL5+ tau lees paub, Desfire 8K EV3 phaib yog nrog AES-128 encryption thiab kev sib koom ua pov thawj los tiv thaiv cov ntaub ntawv rhiab. Thiab cov ntawv teev lus tau rov qab ua tau zoo nrog yav dhau los MIFARE DESFire tiam (EV1, EV2), kom ntseeg tau yooj yim kev koom ua ke rau hauv cov tshuab uas twb muaj lawm.

DESFIRE EV3 8K daim npav ua haujlwm li cas rau ntau daim ntawv thov?
Daim npav siv lub koom haum hierarchical uas cov ntawv thov raug tsim thiab tswj hwm hauv cov qauv kev xav. Txhua daim ntawv thov tuaj yeem suav nrog ntau cov ntaub ntawv uas tuaj yeem nkag mus-tswj nws tus kheej.
Txhua daim ntawv thov ntawm daim npav tau txheeb xyuas tshwj xeeb los ntawm Daim Ntawv Thov Tus Kheej (AID), tso cai rau lub kaw lus lees paub thiab tswj hwm ntau daim ntawv thov tau zoo.
Daim npav DESFire EV3 8K muaj lub cim xeeb tseem ceeb (8K bytes) uas tuaj yeem muab faib ua ntau yam kev siv. Txhua daim ntawv thov tuaj yeem muaj nws tus kheej faib qhov chaw nco rau cov ntaub ntawv thiab cov ntaub ntawv.
DESFire EV3 txhawb nqa ntau tus yuam sij rau ib daim ntawv thov, ua kom muaj ntau theem ntawm kev nkag mus tswj thiab ua kom ntseeg tau tias cov ntaub ntawv rhiab tiv thaiv.
DESFire EV3 daim npav siv cov txheej txheem sib txuas lus ceev ceev, tso cai rau kev nkag mus rau cov ntawv thov sib txawv yam tsis muaj kev ncua sij hawm tseem ceeb, uas yog qhov tseem ceeb hauv ib puag ncig xws li kev tswj xyuas thiab kev them nyiaj uas ceev yog qhov tseem ceeb.
DESFire EV3 daim npav txhawb kev sib koom ua ke kom paub tseeb tias daim npav thiab tus nyeem ntawv txheeb xyuas ib leeg ua ntej txhua daim ntawv thov ua haujlwm, tiv thaiv kev nkag mus tsis tau.
Cov thawj coj muaj peev xwm dynamically ntxiv, rho tawm, lossis hloov cov ntawv thov thiab lawv qhov chaw ntawm daim npav, tso cai rau kev hloov kho yooj yim raws li lub koom haum xav tau hloov.
