Kev Ruaj Ntseg Tiers: Qhov Kev pheej hmoo koj lees txais nrog txhua qhov kev xaiv Chip
Ntawm no yog ib txoj hauj lwm feem ntau cov neeg xa khoom daim npav dawb yuav tsis hais meej meej:MIFARE Classictsis yog ib qho kev xaiv tiv thaiv rau txhua daim ntawv thov uas daim npav cloning sawv cev rau qhov muaj txiaj ntsig zoo.Qhov ntawd suav nrog kev nkag mus hauv lub tuam txhab, cov yuam sij hauv tsev so, cov chaw nres tsheb, thiab qhov tseem ceeb ntawm txhua qhov kev siv uas daim npav sib npaug pub rau lub cev nkag.
Qhov no tsis yog qhov kev txhawj xeeb theoretical. Xyoo 2024, cov kws tshawb fawb txog kev ruaj ntseg ntawm Quarkslab tau tshaj tawm cov khoom siv rov qab hauv FM11RF08S chips, siv dav hauv Suav- cov khoom lag luam sib txawv raws li "MIFARE Classic tshaj." Lub backdoor tso cai ua tiav daim npav cloning hauv feeb, tsis muaj cov cuab yeej tshwj xeeb tshaj li tus nyeem ntawv muag khoom (SecurityWeek). Cov tsev so thoob plaws Tebchaws Meskas, Tebchaws Europe, thiab Is Nrias teb tau pom tias siv cov chips no yam tsis paub tias lawv daim npav tsis yog NXP tiag tiag- tsim MIFARE Classic ICs. Cov pab pawg muag khoom uas tau muab cov lus txiav txim ntsuas tus nqi thiab hais txog kev sib raug zoo, tab sis tsis yog qhov tseeb silicon hauv daim npav.
Yav dhau los kev kawm ua haujlwm los ntawm University College London twb tau ua pov thawj tias txawm tias daim npav MIFARE Classic tuaj yeem raug cloned los ntawm qhov sib thooj ib leeg, tsis muaj kev nyeem ntawv xav tau, siv cov kws tshawb fawb hu ua "daim npav{0}}tsuas yog tawm tsam" (UCL Discovery). Qhov kev tshawb pom Quarkslab tau lees paub tias qhov teeb meem tsis tau tshwm sim xwb tab sis ua phem zuj zus los ntawm kev hloov cov saw hlau.
Txoj hauv kev txhim kho qhov ua tau zoo rau cov koom haum tseem ua haujlwm Classic-raws li daim npav tsis muaj kev sib cuag tsis muaj ntse nyob ntawm cov peev txheej uas twb muaj lawm:
Scenario A - Reader hardware txhawb MIFARE Plus.Hloov mus rau MIFARE Plus daim npav thiab teeb tsa cov neeg nyeem rau Kev Ruaj Ntseg Qib 3 (SL3) hom, uas qhib AES-128 encryption. Qhov no yog tus nqi qis tshaj - txoj kev tsiv teb tsaws chaw vim nws rov siv cov neeg nyeem uas twb muaj lawm, tab sis nws yuav tsum tau hloov kho firmware thiab rov sau npe ntawm txhua daim npav.
Scenario B - Cov nyeem yog kawg- ntawm-lub neej lossis Classic- nkaus xwb.Cov peev nyiaj rau kev hloov pauv nyeem ntawv tag nrho thiab txav ncaj qha mus rau MIFARE DESFire EV3. Tus nqi ib - daim npav yog siab dua, tab sis DESFire's EAL5+ ntawv pov thawj thiab cov qauv kev thov hloov pauv tau txo qis qhov kev pheej hmoo ntawm lwm qhov yuam kev tsiv teb tsaws piv rau Classic-raws li infrastructure.
Scenario C - Tsawg-kev nyab xeeb, tsis yog- daim ntawv thov tseem ceeb(cafeteria loyalty cards, qhua paib). Classic lossis NTAG tseem lees txais, tab sis tsuas yog thaum daim npav tsis muaj cai nkag mus rau lub cev ib yam nkaus. Yog tias koj thaj chaw qhua sib koom tib lub qhov rooj nkag mus rau cov chaw ua haujlwm, txawm tias qee qhov, qhov kev zam no tsis siv, thiab koj yuav tsum ntsuas Scenario A lossis B.
Qhov sib txawv ntawm Scenario A thiab B yog qhov uas feem ntau cov peev nyiaj yuav raug kaw. Tus nqi sib txawv ntawm Plus SL3 tsiv teb tsaws thiab tag nrho DESFire rollout nyob ntawm qhov sib txawv tshwj xeeb rau koj qhov kev teeb tsa: cov lus xauj tsev nyeem ntawv ntxiv, IT headcount rau re- rau npe, thiab seb koj pab neeg ruaj ntseg puas muaj peev nyiaj ncaj qha. Tab sis lub moj khaum kev txiav txim siab yog qhov tseeb. Yog tias koj cov neeg nyeem tau teeb tsa ua ntej 2019 thiab koj muaj kev ua raws cai lossis kev tuav pov hwm yuav tsum tau khi rau kev tswj hwm, tus nqi ntawm kev nyob hauv Classic yog twb siab dua kev tsiv teb tsaws. Cov neeg nyeem feem ntau tau xa mus ua ntej 2019 nkoj yam tsis muaj kev txhawb nqa firmware rau MIFARE Plus Kev Ruaj Ntseg Qib 3, uas txhais tau tias Classic-rau-Plus tsiv teb tsaws tsis yog ib qho kev xaiv thiab tag nrho cov neeg nyeem hloov pauv dhau los ua txoj hauv kev hloov kho tshiab.
Los ntawm Daim Npav Lub Cev mus rau Cov Ntawv Sau Npe: Tau Txais Kev Cai Lij Choj
Ib daim npav ntse dawb tsuas yog ib nrab ntawm cov khoom. Lwm ib nrab yog dab tsi tshwm sim tom qab nws tuaj txog: luam ntawv, encoding, laminating, thiab tshaj tawm. Cov khoom tshwj xeeb uas tsis quav ntsej txog theem thib ob no tsim teeb meem uas tshwm sim tsuas yog thaum tsim khoom.
Cov khoom siv ntawm daim npav lub cev thiab lub tshuab luam ntawv sib raug zoo yog qhov feem ntau ntawm kev ua tsis tiav. Daim ntawv qhia tsis yog qhov yooj yim, thiab tau txais nws tsis raug pov tseg daim npav thiab luam ribbons:
