Yog-NFC cim npe tuaj yeem cloned hauv qee kis, tab sis nws nyob ntawm hnyav heev ntawmhom NFC nti thiab nws cov nta kev ruaj ntseg.
1. Yooj yim NFC cim npe (yooj yim rau clone)
Ntau tus nqi qis -NFC cim npe xws li:
NTAG 213 / NTAG 215 / NTAG 216 (basic versions)
Qee daim npav MIFARE Classic (cov ntawv qub)
feem ntau tuaj yeem yognyeem thiab theejsiv NFC- qhib lub xov tooj lossis sau ntawv app.
Cov cim npe no feem ntau:
Tsuas khaws ib qho yooj yim UID + cov ntaub ntawv (xws li URL lossis ntawv nyeem)
Muajme me los yog tsis muaj kev tiv thaiv cryptographic
Yuav muab duplicated mus rau lwm daim ntawv sau
Piv txwv li: luam daim npav lag luam NFC txuas lossis cov khoom lag luam yooj yim feem ntau yooj yim.
2. Ruaj Ntseg NFC cim npe (nyuaj lossis tsis tuaj yeem ua clone)
Ntau tshaj cov chips suav nrog:
NTAG 424 DNA
DESFire EV2 / EV3
Qee lub txhab nyiaj / nkag mus tswj daim npav
Cov no siv:
Encryption (AES / 3DES)
Dynamic authentication codes
Rolling kev ruaj ntseg qhov tseem ceeb (tsis yog cov ntaub ntawv zoo li qub)
Hauv cov xwm txheej no, txawm tias ib tus neeg nyeem tag, lawvtsis tuaj yeem tsim ua haujlwm clonevim:
Txhua qhov kev sib cuam tshuam tsim cov lus teb cryptographic tshwj xeeb
Cov yuam sij zais tsis tau nyeem tau
3. Qhov txawv tseem ceeb: "kev luam cov ntaub ntawv" vs "cloning tus kheej"
Cim npe:Cov ntaub ntawv feem ntau tuaj yeem luam tawm → "clone-zoo li tus cwj pwm"
Kev ruaj ntseg tag:cov ntaub ntawv ib leeg yog tsis muaj txiaj ntsig yam tsis muaj tus yuam sij cryptographic
Yog li hauv kev ruaj ntseg (kev tswj xyuas, kev them nyiaj, kev tiv thaiv- cuav):
cloning yog zoo tiv thaiv los ntawm kev tsim.
4. Tiag - ntiaj teb no takeaway
Tsawg-nqi NFC daim nplaum →feem ntau tuaj yeem cloned
High -Kev ruaj ntseg NFC systems →tsim tshwj xeeb los tiv thaiv cloning
Yog tias koj xav tau, kuv tuaj yeem piav qhia:
Yuav ua li cas NFC cloning yog technically ua tiav (qib-los ntawm- kauj ruam, tsis yog- cov ntsiab lus tsis zoo)
los yog yuav ua li cas cov tuam txhab tiv thaiv cloning hauv kev tiv thaiv -cov tshuab cuav (muaj feem xyuam rau RFID/NFC cov khoom)
