Panon ya Mankikimey iray Key Card parad saray Hotel? RFID, Magstripe, tan say Teknolohiya ed Likod na Gripo

 

Taloran teknolohiya, taloran nanduruman istorya na seguridad

 

Diad silong na branding, kada kredensyal na kuarto ed hotel et manpapaandar ed sakey ed taloran teknolohiya, tan balang sakey et mandumaan so ugali to no walay nagawan aliwa.

 

Say magnetic stripe so sankadaanan ya format ya uusaren ni ed inagew-agew. Say datos na bisita et manbibilay bilang magnetized particles ed ambilunget a banda ed beneg, tan nabasa itan na kandado legan ya onkukurang so card ed sakey a slot. Say RFID versus magnetic stripe hotel key card tepet et kaslakan ya onggapo dia, lapud say stripe so mura ya opsyon ya mareen ya mas mabli ed saginonor: anggapoy naiimban ton maligen, onkakapuy no naasikaso, tan diad karaklan ya lote et manguusar na abeban-coercivity ya stock ya mangiiter na encoding to ed sakey ya stray magnet odino busy recycle {3} ya mas arawi nen say iilaloan na totoo.

 

Say RFID cards et insaliw toy swipe parad sakey a tap, tan dia et nagmaliw ya makapainteres so pakatalos no panon ya mankikimey iray RFID key cards parad saray hotel. Sakey a melag a chip tan sakey a coil na copper antenna so akasara ed plastik. Say manbabasa ed kandado et mangibubuntok na radio field, satan a field so mamaandar ed chip ya anggapoy baterya tan anggapoy kontak, tan say chip et onebat ya walay aka-store ya kredensyal to. Say frequency so detalye ya lakseben na karaklan ya managpaliwawa.Saray legacy access card et manbabaroy ed 125 kHz, sakey ya abeban frequency band ya ngalngali anggapoy seguridad; say modernon estandarte et 13.56 MHz, say atagey-frequency band ya inabang na MIFARE chip family tan NFC. Pareho so pisika, mandumaan so proteksion depende ed no dinan ya chip so walad tagey.

 

 

Say NFC mobile keys so sankabaloan ya layer, aliwan balon ideya nen say parehon 13.56 MHz ya exchange ya inyalis ed telepono, ya mangi-emulate na card tan mitongtong ed Bluetooth-capable lock ya uusaren iray credentials ya inter ed mobile check-in. Say pull et operational, aliwan uso labat: Nalmoan na research na Cornell ya say limaran-minuton panalagar ed check-in et makabawas na kapaldua ed satisfaction na bisita (BDC Network), tan say ag-onla ed lamisaan et say payoff ya uusaren na saray hotel. Say kuarta et ontutumbok ed uso, ya say teknolohiya na hotel ya anggapoy kontak et mankantidad na ngalngalin US$4.8 bilyon nen 2025 tan iilaloan ya onabot ed ngalngalin US$14.6 bilyon nen 2034 (Dataintelo), tan sakey a manunan chain so walaan na mobile keys ya manbibilay ed masulok ya 1,800 ya hotel nen sampot na 2019 (Teknolohiya ed Panagparawes). Say pilien ya frequency so sankaimportantian no mangibaga na lock hardware. Tayoinkagba na RFID sumpad NFC tan no kapigan i-deploy so kada sakeysakbongan to itan ya desisyon, balet parad balon hotel ya ipaalagey, 13.56 MHz so praktikal ya datal.

 

Diad loob na kapalduan -segundo no nalukasan so sakey a puerta

 

Nabasa na puerta na hotel so card mo tan mandesisyon ed loob na sakey a segundo, tan saray kundang et mas simpli nen say isusuheri na kapeles.Say manbabasa et mangibubuga na radio field, say passive chip et ombangon tan ipawil to so kredensyal ya insulat to, say controller na kandado et ikompara to itan ed access rule ya sankabembenan to, tan no say kuarto tan saray petsa et manlinya, sikatoy mamaandar ed bolt. Ontan so kimey na hotel key card ed lebel ya nanengneng na bisita.

 

Say walad leksab et say parte ya kaukolan ya amtaen: maslak ya kandado na puerta na hotel et offline. Anggapoy live server check, anggapoy network cable. Ginagala itan, ta abuloyan toy sakey a lote ya makapaandar na nilibon puerta ya uusaren so baterya ya anggapoy kable na IT ed kada frame. Say tradeoff et say permission logic et kaukolan ya manbilay ed mismon card, ya saya so eksakton rason no akin ya say credential mo et walaan na sarili ton expiry tan ontundan mankimey no man-checkout imbes ya na-switch off ed arawi, tan, unong ya ipapanengneng na security record, no akin ya say palson card ya walay suston data et makapangilukas na puerta ya agbalot inautorisaan na front desk. Parad card-side mechanics ya sakey a lebel ed leksab, say managpaliwawa tayo etno antoy isimpen na RFID smart card tan panon itan ya onkiwasonla ed aralem.

 

Antoy amta na kard mo nipaakar ed sika, tan antoy agto amta

 

Say paulit-ulit ya kapagaan ed privacy et makanakana ya solusyonan a malinew.

Say card et sakey a token ya mangipapabitar ed sakey a rekord ed loob na sistema na hotel, aliwan kopya na satan a rekord. Ipelag mo ed karsada tan anggapoy naaralan na manag-anap nipaakar ed sika; diad modernon encrypted credential, ag da ni ingen nagawaan itan ya working key ya anggapoy mas ni nen say makapainteres ya ngarem.

 

 

Say history na seguridad ya ag-ipapasen na saray brosyur

 

Say paraan na pankimey na saray key card parad saray hotel et aglabat say inkakombeniente:say teknolohiya na chip ed loob so mangiletneg na limitasyon no panon kaseguro so puerta, tan say industriya so angusar na masulok a sakey dekada pian paneknekan itan.

 

Nen 2012, sakey a Mozilla developer ya nagmaliw ya researcher ya si Cody Brocious so linma ed entablado na Black Hat USA diad Las Vegas ya walay awit ton gadget ya ginawa manlapud manga limamplo-dolyar ya Arduino board. Insaksak to itan ed power-tan-programming port diad leksab na malaknab ya uusaren ya Onity electronic lock, binasa toy memorya na kandado, insan to inlukas so puerta. Saraman ya kandado et walad ngalngalin apatiran anggad limaran milyon a kuarto ed interon mundo. Diad loob na pigaran bulan et parehon teknik so pinmatnag ed saray totoon panagtakew, kaiba lay sakey a laptop ya tinakew ed sakey a Hyatt diad Galleria na Houston, ya diman et inaresto na saray pulis so sakey a suspek; Say remedyo na Onity et say libren port plug tan say firmware-tan-circuit-board upgrade ya iilaloan ton bayaran na saray hotel, tan say pangadapta et abayag (Say Rehistro).

 

Say kaso nen 2024 et mas mairap ya itunda. Imparungtal na sakey a grupo na saray managsukimat so sakey a kadena na saray depekto ya tatawagen ya Unsaflok ya akasabi ed ngalngalin taloran milyon a puerta ed ngalngalin 13,000 a lote ed 131 a bansa (BleepingComputer). Say panangataki et mankaukolan na sakey a keycard ya nabasa manlapud lote tan sakey a mura ya writer pian makagawa na duaran palson baraha, tan say rason no akin ya kaukolan so duara et makanakanan talosan: say unonan kard et mangisulat lamet ed loob na kandado, insan labat nalukasan na komaduan kard (Unsaflok). Nankimey itan lapud saraman ya kandado et akadepende ed daan lan MIFARE Classic card ya walay proprietary key scheme ya nayarin i-reverse-engineered, tan lapud say bolt et nayarin i-pull ed software, say deadbolt et anggapoy peteg ya backstop to. Saray kakapuyan na access-control chip et onabot ed labas na sakey a tatak na kandado, kanian say pilien ya kredensyal imbes ya say tatak na kandado so peteg a kontrol, sakey a tradeoff ya insulat mi ed nota mi edaccess-control card security tan no panon ya pilien.

 

 

Diad nikadkaduman, saray researcher et akaromog na hardware backdoor ed pigaran MIFARE-compatible chips ya ginawa ed China, say klase ya wala lad saray hotel ed interon US, Europe, tan India (TechRadar). Amin na taloran istorya et walaan na sakey a leksion: "manpapaandar itan ed RFID, kanian segurado" et sakey a sentence ya abayag lan maong.

 

No saliwen odino iter mo irayan kard, basaen iray ag-inkayadyari

 

Say encrypted RFID card et mas mairap ya i-clone nen say magnetic stripe. Duga itan ya headline, tan say AI summary so mangulit ed satan ed sika ya maliket. Say mareen ya inekal na sentence et say variable ya mandesisyon no kasin ligtas so kaykayarian mo:no dinan ya pamilya na chip so walad loob, tan no siopay silicon to. Saya so parte ya ag naala na karaklan ya supplier ed sarili da, tan ditan et mandumaan so panmoria na sakey a pabrika ed panmoria na sakey a reseller.

 

Say Bare MIFARE Classic et anggapo lad lamisaan natan, antokaman so tier na lote, lapud say Unsaflok disclosure et nanggawa ed satan ya tawag ya permanente tan say chip ya cryptographically ya aderal manlapu nen 2008 et anggapoy negosyo ton manbabantay na guest room. Say nakekeraan ya desisyonan et no dinan ya encryption-grade chip so matukoy ed saray kandado, budget, tan rollout mo, tan say pampili na key cards parad sakey ya hotel et naapag ed taloran kaso. Say sakey a budget odino legacy ya hotel ya walaan la na magstripe et nayarin makatunongan ya pansiansiaen itan natan tan paeleten so desk procedure tan re-encoding hygiene, lapud say pangekal na working hardware pian nasumpal so peligro ya ag lan balot naabot na saray bisita to et sakey a klase na basura. Say mid-range ya balon ginawa et anggapoy rason to pian mangibaga ed leksab na13.56 MHz ya aka-encrypt ya kredensyal. Say manunan manlalaok na NFC mobile keys et kaukolan to nin siansia so physical fallback card ya aka-encrypt, lapud satan ya fallback so eksakton labay na sakey ya manag-atake.

 

Say pangitunos na kimey et gagawaen mi parad saray kliyente na panag-asikaso: pangi-fit na kredensyal ed modelo na panamagyaw, pangigiya ed panagsaliw na saray aderal a pamilya na chip, tan pangikumpirma ed nanlapuan na silicon pian ag-onsabi so backdoor ya aka-shrink-wrapped. Say kundang ya talagan mandesisyon no kasin ligtas iray puerta yo et samay ag niimprinta dia: no dinan iran dokumento na autorisasyon so kerewen ed sakey a supplier na chip, panon ya kumpirmaen so tuan NXP odino Infineon ya parte imbes ya sakey ya ag lisensyadon clone, tan panon ya basaen iray wala lan card na sakey a lote antis kan man-order lamet. Say checklist et saray nanduruman supplier ya ag da labay ya ibaga, tan i-share mi no kerewen. No manaanap kayocustom-encoded hotel key cards ya ginawa ed sakey a verified, encryption-grade chip, lukasan so tongtongan panamegley na chip, aliwan say artwork; parad saray resort ya onloob ed saray pool, spa, tan event zone, parehon lohika so onloob edRFID wristbands parad pakaloob ed hotel tan resort, tan diadRFID laundry tagsya mangiyakar na linen ed parehon beneg-na-sistema na abung.

 

Say manunan punto

 

Say paraan na panagkimey na key card systems parad saray hotel et manlalapud sakey a kabiangan, say chip, tan say industriya so nambayar ed pangibaliwala ed satan ed loob na taloran milyon a puerta. Antis ya ipawit so ontumbok ya order na card mo, i-verify so chip generation tan say nanlapuan to, tratoen so antokaman ya ginawa ed bare MIFARE Classic bilang non-starter, tan kerewen ed supplier mo ya paneknekan to no iner so nanlapuan to. No ag da nayarian, satan so ebat mo, tan saya so dugan panaon pian mangawit na pabrika ya sarag to.
