Famba chero chiitiko chakakura uye iyo VIP lanyard ndiyo inonyanya kuoneka chiziviso pane saiti. Iyo zvakare, kazhinji pane kwete, iyo inowana kuongororwa kushoma pane yekutenga odha. Chiratidzo, ruvara, chip "yekuwana": yakabvumidzwa. Mukaha uripo pakati pekuti chitarisiko cheprimiyamu chinotaridzika sei uye chinotevedzwa neRFID VIP lanyard ndipo panotangira matambudziko mazhinji ekuwana VIP.

 

Izvi zvakanyorerwa vanhu vane sarudzo iyi: kutungamira kwezviitiko, pa-mamaneja ekuchengetedzwa kwesaiti, zvikwata zvenzvimbo, uye vanobatanidza vachitarisisa magwaro emakonzati, makonferensi, nenzvimbo dzinodzorwa. Pfungwa apa haisi yekukutengesa paRFID. Iko kukubatsira kuti utaure chiziviso chinodzivirira VIP tier kubva kune inongoonekwa chete.

 

 

Lanyard inogona kubviswa, uye izvo zvinoshandura mubvunzo wese wekuchengetedza

 

Hechino chokwadi chisina kugadzikana vatengesi vazhinji vanosvetuka yapfuura. Lanyard, nekugadzirwa, inobviswa. Panguva iyo mubati wepachokwadi anobvisa gedhi, chiziviso chinogona kubva uye kudzoka nepamusoro pefenzi kune mumwe munhu akamirira kunze. Gadzirira kupisa-bhande remumaoko rakavharwa rinoparara pakubviswa, aRFID lanyard vs wristbandkuenzanisa ichokwadi mubvunzo mumwechete wakavanzika: kutamiswa. Iyo wristband inopikisa kupfuura-kumashure zvimiro; iyo lanyard haina. Kana pass-back resistance chiri chisungo chako chekutanga, cheduRFID wristbands yefesti uye{0}}mazuva akawanda kupindandiwo maitiro akagadzirirwa.

 

Hapana chimwe cheizvi chinobvisa lanyard. Inoidzokorora. Lanyard inowana nzvimbo yayo nekuti inopfeka zvakanaka kwemazuva mazhinji, inoburitswa mumasekonzi, uye inopetwa iine chibatiso chebheji uye ID yemufananidzo. Chaisingakwanise kuita kumanikidza kuzivikanwa kwayo pachayo.

Iyo chip lottery: nei "RFID lanyard" pane quote hairevi chinhu

 

 

Mazhinji ekutenga specs anoti "RFID lanyard" uye mira ipapo. Mutsara mumwe chete iwoyo unovanza iyo inonyanya kukosha sarudzo mukuvaka kwese, nekuti "RFID" inotambanudzira machipisi ari epasirese pakuchengetedza.

 

Chimiro chenguva yakaderera-chinosvika mutengi ane mutengo wakaderera kazhinji iMIFARE Classic{1}}chip chemhuri, kana "MIFARE-inowirirana" isina rezenisi yakaenzana. Iyo mhuri Crypto1 cipher yakaputsika makore apfuura uye inogona kukundwa neyakachipa, inowanikwa zvakanyanya. Zvakabva zvatonyanya kuipa: muna 2024, vaongorori vakaburitsa backdoor mumamiriyoni eFudan FM11RF08S uye FM11RF08 machipi anoita kuti munhu anorwisa atore kadhi mushure memaminitsi mashoma epedyo, uye akawana machipisi aya apararira chinyararire mumasisitimu ekupinda muUS neEurope.SecurityWeek). Mutengi akaodha "custom RFID lanyard" asina kudoma zita chip anogona kunge akabata izvi chaizvo uye asingazive.

 

Kune yechipiri, yakanyarara kutadza modhi: masisitimu anosimbisa pane chip's UID chete. UID haisi chakavanzika. Mategi asina chinhu, anonyoreka ngaaite chero munhu aise UID isina kufanira, saka UID-muverengi chete anogona kunyengedzwa nekakoni inodhura pocket change kugadzira. Kuti uwane yakazara primer yekuti chip mhuri uye mafambiro mepu kune chaiwo maapplication, edugwara kuRFID chip uye kusarudzwa kwechokwadiinofamba nepakati pekutengesa. Kubasa reVIP kutora kupfupi: mhuri yechip uye nzira yechokwadi, kwete izwi rekuti "RFID," sarudza kana chitupa chako chichiramba cloning.

Kutsanangura VIP lanyard inonyatso simudza

 

Yakawanda yenjodzi iri pamusoro inonyungudika padanho rekutsanangurwa, zvakapa iwo mazita ekuti zvinhu zvakakosha kwete izvo zvinotora mifananidzo zvakanaka. Kuti uwane RFID lanyard yemisangano kana inodzorwa-zviitiko zvekuwana, simbirira pazvinhu izvi:

 

• Mhuri yeChip uye chikamu chenhamba mukunyora: DESFire EV2/EV3 kana NTAG 424 DNA kune chero humbowo hunovhura nzvimbo yakarambidzwa, isingambove isina kudomwa zita "MIFARE inoenderana."
   
• Kusiyanisa kwakakosha uye encryption kwakasimbiswa: pa-makiyi ezvitupa, AES-based authentication, uye muverengi plus backend inosimbisa cryptographically pane paUID.
   
• Chitupa chinosungirwa: kunyoreswa kunobatanidza magwaro ega ega kune ane muridzi ane zita, nekuona mapikicha ari pamusoro-magedhi eukoshi.
   
• Zviyero uye kusimba: ISO/IEC 14443 yeHF/NFC kana ISO/IEC 18000-63 yeUHF, pamwe netamper{3}}inooneka, ziya{4}} uye UV-isingachinji chivakwa chinoramba kupfeka kwemazuva mazhinji.
   
• Kuvharwa uye kuchengetedzwa chiyero: kupatsanurwa kwekuchengetedza mutsipa, inoyerwa maererano nechokwadi chekuti kusunungurwa kuri nyore zvakare kunorerutsa kutamiswa, saka kwaunobvumira kuputsika, zembera zvakanyanya pakusunga chitupa.

 

A spec inovhara izvo zvishanu zvakasimudza pasi pekuongorora. Pazvichiri kuruma ndiko kupindirana kuri pakati pawo: kuvharwa kwechimbi-chimbi uye kupfuudza-kumashure kwekudzora kunodhonzerana, uye kuti ndeipi inokunda zvinoenderana nemagadzirirwo egedhi rako uye kana uchikwanisa kuisa pikicha yekuongorora kumusoro. Iyo tradeoff ndiyo chikamu chetemplate chekutarisa chausingakwanise kukugadzirisa iwe; titumire runyorwa rwenzvimbo uye isu tichataura kuvharwa nekusungirirwa kuti tienderane nayo.

 

Iko kunobva chokwadi kunobva kuzvinhu

 

Ichi ndicho chikamu chinotungamirwa nemutengi wesoftware chete haakwanise kupindura nekuvimbika, nekuti vanotenga mapindiro avo semabatiro anoita munhu wese. Kana fekitori ichibatanidza machipisi ayo uye ichiisa maantenna ayo, sarudzo yechip inomira kuva chakavanzika chinodhonzwa kubva mubhini. Pamitsetse yedu, antenna winding inobatwa kusvika ± 0.1 mm saka chinhambwe chekuverenga chinoramba chichienderana kubva kune tag kuenda kune tag, uye humbowo hwese hunoyedzwa frequency, kuverenga renji, uye kuvimbika kwedata isati yatumirwa, iri zvakare mabatirwo eClassic chip anochengetedzwa kunze kwekurongeka kwairehwa kuve kwakachengeteka. Iyo nhanho yekutonga, inotsigirwa neISO9001 uye CE maitiro uye anosvika makumi maviri emakore ekuvaka nhoroondo, ndiwo mutsauko uripo pakati pemutengesi anogona kutumidza chip yako uye uyo anotarisira kuti haumbo bvunza.
