MIFARE NFC thev naus laus zis yog lub tshuab tsis siv neeg lub ntsej muag ntse uas muab kev nyab xeeb thiab yooj yim kev lag luam, tswj kev nkag mus, thiab lwm yam kev siv uas xav tau kev lees paub thiab cov ntaub ntawv encryption. Kev lees paub tseeb yog ib qho tseem ceeb hauv kev ua kom muaj kev ruaj ntseg ntawm MIFARE-enabled systems. Hauv tsab xov xwm no, peb yuav tshawb xyuas cov txheej txheem authentication ntawm MIFARE NFC thev naus laus zis thiab nws ua haujlwm li cas los tiv thaiv cov neeg siv cov ntaub ntawv.
Txheej txheem cej luam ntawm MIFARE Authentication
MIFARE NFC thev naus laus zis siv cov txheej txheem kev lees paub raws li qhov tseem ceeb symmetrical algorithm. Qhov no txhais tau hais tias ob daim npav lossis lub cuab yeej thiab tus nyeem ntawv yuav tsum qhia tus yuam sij zais cia uas siv los txheeb xyuas qhov tseeb ntawm daim npav lossis khoom siv. Tus yuam sij no ruaj ntseg khaws cia rau hauv daim npav lossis lub cuab yeej thiab raug tiv thaiv los ntawm kev nkag tsis tau. Cov txheej txheem authentication muaj xws li kev sib pauv cov ntaub ntawv ntawm daim npav lossis lub cuab yeej thiab tus nyeem ntawv, siv tus yuam sij zais cia los encrypt thiab decrypt cov ntaub ntawv.
MIFARE Authentication txheej txheem
MIFARE authentication txheej txheem muaj peb kauj ruam tseem ceeb:
Kauj ruam 1: Pib pib
Tus nyeem ntawv xa cov lus txib mus rau daim npav lossis lub cuab yeej los pib cov txheej txheem authentication. Cov lus txib no suav nrog tus lej xov tooj thiab tus lej txheeb xyuas qhov tseeb.
Kauj Ruam 2: Sib tw thiab teb
Daim npav lossis cov cuab yeej teb rau cov lus txib pib los ntawm kev xa tus lej random lossis "kev sib tw" rau tus nyeem ntawv. Tus nyeem ntawv mam li encrypts qhov kev sib tw uas siv tus yuam sij zais cia thiab xa rov qab mus rau daim npav lossis khoom siv.
Kauj Ruam 3: Kev Tshawb Fawb
Daim npav lossis lub cuab yeej decrypts qhov kev sib tw encrypted siv tus yuam sij zais cia thiab muab piv rau qhov kev sib tw thawj zaug. Yog tias qhov kev sib tw decrypted yog qhov sib tw thawj zaug, cov txheej txheem kev lees paub tau ua tiav, thiab daim npav lossis cov cuab yeej raug suav tias yog qhov tseeb.
Cov txiaj ntsig ntawm MIFARE Authentication
MIFARE authentication txheej txheem muab ntau yam txiaj ntsig:
- Kev Ruaj Ntseg Muaj Zog: MIFARE authentication siv lub symmetric tseem ceeb algorithm uas muaj kev nyab xeeb heev thiab tiv taus kev nyiag thiab kev dag ntxias.
- Ceev thiab Ua Tau Zoo: Cov txheej txheem authentication yog ceev thiab ua tau zoo, tso cai rau kev nkag tau yooj yim thiab yooj yim rau MIFARE-enabled systems.
- Kev sib koom ua ke yooj yim: MIFARE authentication tuaj yeem yooj yim ua ke rau hauv cov txheej txheem thiab cov txheej txheem uas twb muaj lawm, ua rau nws muaj kev xaiv nrov rau ntau lub koom haum thiab kev lag luam.
Cov txheej txheem authentication yog ib qho tseem ceeb ntawm MIFARE NFC thev naus laus zis, ua kom muaj kev ruaj ntseg thiab ceev ntiag tug ntawm cov neeg siv cov ntaub ntawv. MIFARE authentication txheej txheem yog ua raws li qhov tseem ceeb algorithm symmetrical, muab kev ruaj ntseg ruaj khov, ceev thiab siv tau zoo, thiab kev sib koom ua ke yooj yim rau hauv cov tshuab uas twb muaj lawm. Raws li MIFARE NFC thev naus laus zis txuas ntxiv txhim kho thiab nthuav dav, kev lees paub yuav yog qhov tseem ceeb ntawm nws txoj kev vam meej.
