Yuav Ua Li Cas Ruaj Ntseg Yog RFID Hotel Key Cards thiab Cov Pob Khoom Tseem Ceeb Lawv Nkoj Hauv?

 

Cov pob ntawv tseem ceeb, tus tuav daim npav tseem ceeb, lossis lub hnab ntawv tseem ceeb - Koj yuav qhov twg tiag?

 

Lub sij hawm yog me ntsis overloaded, tsim nyog clearing ua ntej qhia dab tsi. Hauv kev tos txais qhua, ib pob ntawv tseem ceeb (tseem hu ua lub hnab ntawv tseem ceeb, lub tes tsho keycard, lossis daim npav tseem ceeb) yog cov ntawv luam tawm lossis daim npav - tus tuav cov khoom hauv chav tsev tseem ceeb swb rau ntawm daim tshev -in. Nws tiv thaiv daim npav los ntawm kev khoov thiab demagnetization, muab lub rooj rau pem hauv ntej kom sau tus lej ntawm chav tsev, thiab nqa cov cuab yeej lub npe. Ntawm nws tus kheej nws tsis muaj hluav taws xob ua haujlwm.

 

Ob yam khoom lag luam tsis sib xws sib koom ua ke thiab qee zaus tshwm sim hauv tib qhov kev tshawb fawb: cov khoom tseem ceeb ntawm lub cev siv nyob rau hauv tiag - kev tshuaj xyuas vaj tsev (qee zaum "cov pob ntawv tseem ceeb"), thiab cov hlwv - cov ntim tshuaj muag hauv cov npe xws li Key-Pak. Yog tias daim ntawv teev npe luv ntawm cov neeg xa khoom suav nrog ib qho ntawm cov no, lawv tab tom daws qhov teeb meem sib txawv nkaus, tsim nyog tshaj tawm thaum ntxov kom lub hnab ntawv tseem ceeb ntawm RFP tsis muaj muddled.

 

Rau txhua yam hauv qab no, peb txhais tau hais tias lub tsev tos qhua: daim ntawv lub tes tsho, thiab, qhov tseem ceeb tshaj, RFID lossis daim npav sib nqus -stripe card uas nkag mus rau hauv nws.

 

Ob qhov kev txiav txim siab tiag tiag txiav txim siab txog kev ruaj ntseg: Chip Qib thiab Xauv Compatibility

 

Thaum lub pob ntawv tawm ntawm lub rooj raws li qhov muaj kev ruaj ntseg, kev yuav khoom los ntawm ob qhov sib txawv: dab tsi nti nyob rau hauv daim npav, thiab seb lub nti tus encoding zoo li cas rau koj lub xauv platform. Saflok, Onity, Dormakaba, thiab cov tshuab zoo sib xws txhua tus xav tau cov ntaub ntawv sib txawv me ntsis ntawm daim npav.

 

 

Qhov ntawd zoo li tsis tseem ceeb ntawm daim ntawv spec. Ntawm no yog qhov uas nws tso tseg tsis tseem ceeb rau ib qho khoom. Ib pawg ntawm 500 phaib mus rau ib lub tsev so nyob rau sab hnub tuaj Asia tau nyeem zoo kawg nkaus ntawm tus nyeem ntawv demo ntawm peb lub rooj zaum: lub teeb ntsuab, nyeem tau, txhua daim npav. Ntawm qhov chaw, txhua daim npav pov "daim npav tsis raug" ntawm lub qhov rooj. Ob hnub ntawm kev kuaj mob tej thaj chaw deb taug qab nws mus rau lub firmware hloov tshiab lub xauv chaw tsim tshuaj paus tau thawb txog peb lub hlis dhau los uas tau hloov pauv li cas cov ntawv txheeb xyuas tau raug lees paub; tus encoding profile peb tau muab predated nws. Daim card Tshuag thiab luam ntawv tau flawless. Lub qhov rooj tseem tsis qhib. Qhov sib txawv ntawm "nyeem ntawm lub rooj ntev zaum" thiab "qhib qhov rooj" yog raws nraim qhov twg anti-clone tsev so key card txiav txim ntsiag to mus tsis ncaj ncees lawm.

 

Durability qhia ib zaj dab neeg zoo sib xws, thiab koj tsis tas yuav coj nws los ntawm kev ntseeg; nws tshwm nyob rau hauv lub voj voog reorder. Raws li cov qauv kev lag luam ntxhib, sib nqus- daim npav kab txaij feem ntau xav tau hloov pauv hauv 6-12 lub hlis ntawm cov qhua hnyav, thaum cov npav RFID tau txais txiaj ntsig zoo feem ntau khiav 2-3 xyoos nyob rau hauv tib lub thauj khoom. Tus nqi ib daim npav ib zaug uas yuav tsum tau rov ua peb zaug raws li feem ntau tsis pheej yig dua; nws yog nyiaj ntsuab-txoj kev txiav txim siab hnav ib chav tsev- tus nqi costume.

 

Yuav ua li cas Hotel Key Cards Tau Cloned hauv Teb

 

Nws tsim nyog nkag siab txog cov txheej txheem, vim tias "RFID daim npav tuaj yeem cloned" tau hais tias yog qhov tseeb tsis muaj qhov tseeb.vim li cas, thiab covvim li casyog qhov qhia rau koj tias daim npav twg yeej muaj kev pheej hmoo.

 

Qhov teeb meem qub tshaj plaws thiab nthuav dav tshaj plaws tau taug qab mus rau MIFARE Classic's Crypto-1 cipher, uas cov kws tshawb fawb kev kawm ntawm Radboud University thim rov qab-engineered kom deb li deb rov qab rau xyoo 2008 (IACR ePrint Archive - tus tshaj tawm). Daim npav ntawm tsev neeg cov ntawv txheeb xyuas nrog lub tswv yim uas tau tshaj tawm rau ntau tshaj kaum xyoo, tsis tau, vim tias muaj ntau yam khoom siv kho vajtse nyob ntawm nws, nws tseem nyob hauv cov khoom uas tsis tau hloov kho dua tshiab.

 

Cov ntaub ntawv tshiab thiab txawv txawv tshwm sim nyob rau xyoo 2024: ib lub nti tso tawm tshwj xeeb los kaw cov qub cloning qhov khoob (FM11RF08S) tau tawm los nqa nws tus kheej kho vajtse - theem qhov tsis zoo, cia tus neeg tawm tsam nrog ob peb feeb ntawm lub cev nkag mus rau ib daim npav rho tawm cov cuab yeej tag nrho cov kev cai tseem ceeb (Xov xwm Hacker). Lub takeaway tsis yog "zaum ntawd ib nti." Nws yog tias daim ntawv qhia kev lag luam nti ("kho dua tshiab," "encrypted," "tom ntej- tiam") tsis yog qhov hloov pauv rau kev tshuaj xyuas nws txoj kev lees paub tseeb. Daim npav uas cia siab rau tsis muaj dab tsi ntau dua li daim npav ID zoo li qub, tsis muaj kev sib pauv cryptographic ntawm daim npav thiab lub xauv, yog qhov yooj yim tshaj plaws ntawm txhua tus kom duplicate nrog cov khoom siv pheej yig, txawm li cas los xij ntawm lub ntim hais. Yog tias skimming ntawm lub qhov rooj yog ib feem ntawm koj tus qauv kev hem thawj, qhov ntawd yog ib kab tshwj xeeb. Ib shieldedRFID- thaiv daim npav lub tes tshochaw nyob cuam tshuam, tsis cloning, thiab ob qho tib si tsis meej pem tas li.

 

Kev Qhia Txog Daim Npav Ruaj Ntseg: AES, MIFARE Plus SL3, thiab Kev Sib Koom Tes

 

Qhov kev kho tsis nyuaj thaum lub chip toj roob hauv pes pom meej, thiab nws tsis muaj dab tsi cuam tshuam nrog cov pob ntawv tseem ceeb uas daim npav thauj khoom hauv. Kev lag luam tab tom txav deb ntawm UID-tsuas yog thiab Crypto-1 daim npav mus rau chips siv AES-128 encryption nrog kev sib koom ua pov thawj: daim npav thiab tus nyeem ntawv txhua tus txheeb xyuas lwm yam ua ntej kev nkag mus rau cov ntaub ntawv ID.

 

Chip Hom	Authentication Method	Cloning Resistance	Hom Siv Case Niaj hnub no
UID-tsuas yog / qhov sib thooj	Static ID nkaus xwb	Tsawg heev	Legacy, raug phased tawm
MIFARE Classic (Crypto-1)	Proprietary cipher, tawg txij li xyoo 2008	Tsawg	Loj ntsia lub hauv paus, txhim kho tus neeg sib tw
MIFARE Plus SL3	AES-128, kev sib koom ua ke	Siab	Txoj hauv kev txhim kho txoj hauv kev rau feem ntau cov khoom
DESFire EV-series	AES-128 / 3DES, kev sib koom ua ke	Siab	Siab dua -kev ruaj ntseg lossis ntau- daim ntawv thov xa tawm

 

AES-128 tam sim no raug kho thoob plaws hauv kev nkag mus- tswj kev lag luam raws li kev suav tsis tuaj yeem ua rau brute- quab yuam nrog cov neeg siv khoom lossis cov khoom lag luam uas twb muaj lawm, uas yog vim li cas MIFARE Plus SL3 tau dhau los ua qhov chaw nruab nrab siv tau rau cov khoom tsiv tawm ntawm Classic- raws li lub nkoj es tsis yog dhia ncaj nraim mus rau tag nrho DE. Tab sis qhov kev pom zoo no muaj qhov xwm txheej feem ntau cov neeg muag khoom yuav tsis tsa sawv cev rau koj: SL3 tsuas yog pab yog tias koj lub xauv xauv 'firmware yeej txhawb kev nyeem nws ntawm qib kev ruaj ntseg uas koj them rau. Txoj hauv kev kom paub meej tias tsis yog los lees txais daim ntawv qhia nti; nws yog los thov lub xauv qhov sau firmware version naj npawb thiab muaj ib daim npav qauv kuaj tawm tsam qhov tseeb firmware ua ntej koj kos npe tawm. Ordering SL3 phaib tiv thaiv cov xauv tseem tau teeb tsa rau Classic-qib nyeem yog ib txoj hauv kev uas cov haujlwm no nyob ruaj khov, thiab tseem muaj lub hauv paus loj heev ntawm cov cuab yeej cuab tam MIFARE hauv thaj teb kom ua qhov yuam kev yooj yim. Qhov no kuj yog qhov chaw ruaj ntseg tsev so key card program thiab kev sib txuamRFID keyfobCov ntaub ntawv pov thawj muaj nyob rau hauv tib lub spec, yog li cov neeg ua haujlwm thiab cov qhua tuaj yeem khiav ntawm tib daim ntawv pov thawj nti es tsis yog daim npav muaj zog ua ke nrog fob tsis muaj zog.

 

Peb Qhov Kev Txiav Txim Siab Uas Tsis Muaj Nqis Ob zaug

 

Ib tug puv tes ntawm cov qauv qhia ntau txaus thoob plawstsev so key card xajhais tias lawv tsim nyog naming ncaj qha, vim hais tias txhua tus nyiam mus nrhiav tau tsuas yog tom qab lub nkoj nkoj.

Tsis txhob lees txais kev lees paub ntawm no. Nug rau tus naj npawb ntawm cov nti hauv kev sau ntawv thiab cov ntaub ntawv firmware-cov txiaj ntsig kev sib raug zoo tiv thaiv koj tus qauv xauv tshwj xeeb ua ntej PO tau tshaj tawm. Qhov thib ob yog kho qhov xauv-platform compatibility raws li tus neeg muag khoom qhov teeb meem los daws tom qab qhov tseeb es tsis yog ib qho spec paub tseeb ua ntej ntau lawm. Qhov ntawd yog raws nraim li cas cov batch xaus li luam tawm kom raug thiab tsis tuaj yeem qhib ib lub qhov rooj. Qhov thib peb yog xav tias lub xov tooj ntawm tes lossis xov tooj -raws li tus yuam sij tau txais kev nyab xeeb dua li daim npav lub cev; nyob rau hauv feem ntau tam sim no deployments lub xov tooj yog simulating tib lub hauv paus nti daim ntawv pov thawj, yog li ib tug tsis muaj zog nti txheem tsis tau muaj zog vim hais tias nws twb npaj mus rau ib tug screen.

 

Ntawm no yog vim li cas "poob tom qab lawv nkoj" yog qhov kim, pom tseeb. Ntawm 5,000- daim npav khiav, thawj ob peb puas daim npav ua piv txwv ntawm kev pom zoo nyeem zoo; cov kev ua tsis tiav yuav tsis nto mus txog thaum cov cuab yeej encoding thiab tawm ntawm ntim, thaum nyeem - tus nqi tsis ua haujlwm tuaj yeem pib nce qhov chaw dhau los ntawm 3,000th daim npav, ib zaug marginal encoding lossis kav hlau txais xov- qhov teeb meem tuning tau rov ua dua thoob plaws tag nrho. Los ntawm ces qhov kho tsis yog re-spec, nws yog re-manufacturing. Qhov ntawd yog qhov sib npaug zais tom qab tus nqi qis ntawm cov pob ntawv tseem ceeb.

 

Dab tsi tshwm sim ntawm Peb Cov Khoom Siv Hauv Tsev Ua Ntej Daim Npav Nkoj

 

Qhov no yog feem ntau cov neeg muag khoom nyob rau hauv pawg no tsis tuaj yeem hais lus rau, vim tias feem ntau ntawm lawv rov muag cov ntawv teev npe nkag los ntawm lwm tus. Chip bonding thiab encoding yog ob kauj ruam uas teeb meem kev sib raug zoo feem ntau tshwm sim, thiab ob kauj ruam uas tus neeg faib khoom feem ntau tsis muaj kev pom.

 

 

Peb khiav ob leeg hauv -tsev. Qhov ntawd txhais tau hais tias tuav kev tos txais qhua tuaj yeem nyob rau hauv thaj tsam ntawm ob lab daim npav ib xyoos rau cov neeg siv khoom rov ua dua, ntxiv rau qhov ntim zoo sib xws rau ntev -khiav kev lom zem- kev sib koom ua ke ntawm cov chaw ua si. Cov no yog cov qauv reorder uas tsuas yog tuav tau yog tias encoding thiab nyeem kev ntseeg tau nyob twj ywm batch tom qab batch, tsis yog ntawm cov qauv pom zoo. Txhua daim npav tawm hauv pem teb mus dhau 100% kev ntsuas cov zis ua ntej packing, uas yog cov kauj ruam uas catches ib tug encoding mismatch ua ntej nws yuav ua rau pem hauv ntej - rooj teeb meem es tsis txhob tom qab.
