Ol RFID Hotel Ki Kad na ol Ki Paket Ol i Salim I Stap Gut Olsem Wanem?

 

Ki Paket, Ki Kad Holda, o Ki Envelop - Yu Baim Wanem Wanpela Tru?

 

Dispela tok i pulap liklik, na i gutpela long kliarim pastaim long yu tok klia long wanpela samting. Insait long 'hospitality supply', wanpela 'key packet' (ol i kolim tu olsem 'key card envelope', 'keycard sleeve', o 'key card folder') em i pepa o kad-stock holda we ol i prinim we ki bilong rum i save putim i go insait long taim bilong sekim-in. Em i lukautim kad long tanim na rausim magnet, na givim ples long fran desk long raitim namba bilong rum, na i gat nem bilong haus. Long em yet em i no gat wok bilong elektronik.

 

Tupela prodak we i no wankain i gat wankain nem na sampela taim i save kamap long wankain sekim risal: ol fisikel ki set we ol i save yusim long ol 'real-estate inspeksen (sampela taim "inspekta ki paket"), na blister-pek marasin paket we ol i salim aninit long nem olsem Key-Pak. Sapos wanpela sotlis bilong ol saplaia i gat wanpela bilong ol dispela, ol i wok long stretim narapela hevi olgeta, na i gutpela long makim pastaim bai wanpela 'bulk key card envelope RFP' i no ken paul.

 

Long olgeta samting i kamap bihain, mipela i minim 'hospitality' vesen: pepa 'sleeve', na, bikpela samting moa, RFID o 'magnetic-stripe' kad we i go insait long en.

 

Tupela disisen we i save makim sekyuriti: Chip Gred na Lock Kompatibiliti

 

Taim paket i no stap long tebol olsem wanpela sekyuriti fakta, baim i kam daun long tupela samting: wanem sip i stap insait long kad, na sapos enkoding bilong dispela sip i wankain olsem lok pletfom bilong yu. Saflok, Onity, Dormakaba, na ol narapela sistem olsem, olgeta wan wan i ting bai i gat ol narapela narapela data straksa long kad.

 

 

Dispela i luk olsem samting nating long wanpela 'spec sheet'. Em i stop long stap olsem samting nating long wanpela propeti. Wanpela lain bilong 500 kad i go long wanpela Saut-is Esia risot sen i ritim gut tru long demo rida long bens bilong mipela: grin lait, gutpela ritim, olgeta kad. Long sait, olgeta kad i tromoi "invalid card" long dua. Tupela de bilong 'remote diagnosis' i soim olsem em i go long wanpela 'firmware' apdet we kampani i wokim ol 'lock' i bin putim tripela mun i go pinis we i senisim hau ol i bin skelim 'sector checksum'; 'encoding profile' we ol i bin givim mipela i bin stap pastaim long en. Ol kad stok na printing i no gat asua. Ol dua i no op yet. Dispela spes namel long "ritim long benk" na "opim dua" em i ples stret we ol oda bilong ol ki kad bilong 'anti-clone hotel i save go rong.

 

Durability i stori wankain, na yu no nid long kisim long bilip; em i kamap long 'reorder cycle'. Olsem wanpela mak bilong indastri, ol 'magnetic-stripe' kad i save nidim senis insait long 6-12 mun bilong bikpela ges trafik, tasol ol RFID kad we i gat gutpela enkode i save ron 2-3 yia aninit long wankain lod. Wanpela prais bilong wan wan-kad we ol i mas mekim tripela taim planti taim em i no liklik pe; em i wanpela 'cash-flow' disisen we yu werim wanpela yunit-kos kostum.

 

Olsem wanem ol hotel ki kad i save kamap klostu long gaden

 

Em i gutpela long kliagut long wok bilong en, long wanem, "ol i ken 'clone' ol RFID kat" em i wanpela samting we i no gatbilong wanem, na olbilong wanemem i samting we i save tokim yu wanem ol kad i stap long hevi.

 

Olpela na bikpela hevi tru i kamap long MIFARE Classic's Crypto-1 cipher, we ol akademik risetsa long Radboud Yunivesiti i bin senisim long 2008 (IACR ePrint Archive). Ol kad long dispela 'chip family' i save kamap tru wantaim wanpela skim we ol i bin brukim long pablik long moa long 10-pela yia, tasol, bikos planti 'hardware' i dipen long en, em i stap yet long ol haus we ol i no bin apgredim.

 

Wanpela nupela na narakain samting i kamap long 2024: wanpela 'chip' we ol i bin putim aut stret long pasim olpela 'cloning gaps' (FM11RF08S) i kamap olsem em i gat 'hardware-level flaw bilong en yet, na larim wanpela birua i gat sampela minit bilong fisikel akses long wanpela kad na kisim olgeta 'custom key set' bilong propeti (Nius bilong Hacker). Bikpela samting em i no "abrusim dispela wanpela 'chip'." Em i olsem 'marketing label' bilong wanpela 'chip' ("apgredim," "enkriptim," "neks-jeneresen") i no inap long senisim sekim trupela 'authentication method' bilong en. Ol kad we i no gat wanpela samting moa long wanpela 'static card ID', na i no gat 'cryptographic exchange' namel long kad na lok, em i isi tru long wokim wankain wantaim ol 'commodity hardware' we i no gat bikpela pe, maski wanem samting i stap long pepa bilong en. Sapos 'skimming' long dua em i hap bilong 'threat model' bilong yu, dispela em i wanpela seperet 'spec line'. Wanpela sildedRFID-blokim kad slevi toktok long 'interception', i no 'cloning', na tupela i save paul oltaim.

 

Toksave long wanpela gutpela kad: AES, MIFARE Plus SL3, na Mutual Authentication

 

Wok bilong stretim dispela hevi i no hat taim 'chip landscape' i klia, na em i no gat wok long 'key packet' we kad i salim i go insait long en. Indastri i wok long lusim UID-tasol na Crypto-1 kad i go long ol 'chip' we i yusim AES-128 enkripsen wantaim 'mutual authentication': kad na rida i save sekim narapela narapela pastaim long ol i kisim ol data, na i no trastim rida wanem kain ID wanpela kad i soim.

AES-128 i stap nau long olgeta hap bilong 'access-control' indastri olsem wanpela samting we i no inap long yusim 'brate-force wantaim ol 'consumer' o 'commercial hardware', na dispela i as na MIFARE Plus SL3 i kamap olsem gutpela namel graun bilong ol samting we i lusim wanpela 'Classic-' fleet na i no go stret long SF. Tasol dispela rekomendesen i gat wanpela kondisen we planti saplaia bai no inap long kamapim long nem bilong yu: SL3 i helpim tasol sapos 'firmware' bilong ol lok yu putim i sapotim ritim long sekyuriti level yu baim. Rot bilong konfemim dispela em i no long kisim wanpela 'chip datasheet'; em i bilong askim long raitim namba bilong 'firmware' na kisim wanpela 'sample card' we ol i testim wantaim dispela 'firmware' pastaim long yu sainim. Odaim ol SL3 kad agensim ol lok we i stap yet long ol Klasik-level rid em i wanpela komon rot we ol dispela projek i save stop, na i gat bikpela install beis bilong ol legacy MIFARE hatwea i stap yet long fil bilong mekim dispela asua i isi long mekim. Dispela em tu ples we wanpela gutpela hotel ki kad program na wanpela samting we i wankainRFID ki fobol 'credential' i stap insait long wankain 'spec', olsem na ol wokman na ol ges i save ron long wankain 'chip tier' na i no long wanpela strongpela kad wantaim wanpela wikpela 'fob'.

 

Tripela rong bilong kisim samting we i kostim tupela taim

 

Sampela paten i save kamap planti taim longhotel ki kad odaolsem ol i gutpela long kolim nem bilong ol stret, long wanem, ol i save painim olgeta wan wan bihain long ol i salim ol kad i go.

Noken kisim wanpela toktok bilong tok promis long hia. Askim stretpela namba bilong hap bilong 'chip' long rait na wanpela 'firmware-compatibility test result agensim 'lock model' bilong yu pastaim long ol i givim PO. Namba tu em long tingim 'lock-platform compatibility olsem hevi bilong saplaia long stretim bihain long samting i kamap na i no olsem wanpela 'spec' we ol i bin konfemim pastaim long prodaksen. Em i wankain olsem wanpela 'batch' i save pinis long prinim stret na i no inap long opim wanpela dua. Namba tri em long ting olsem wanpela mobail o fon-ki i stap gut moa long wanpela fisikel kad; long planti ol 'deployment' bilong nau fon i wok long bihainim wankain 'underlying chip credential', olsem na wanpela 'chip standard' we i no strong tumas i no save kamap strong moa bikos ol i soim long skrin.

 

Em i as na "painim bihain long ol i salim" em i samting we i gat bikpela pe, tru tumas. Long 5,000-kad ran, ol namba wan handet kad we ol i kisim long taim bilong tok orait i orait; ol hevi i no kamap inap long taim dispela samting i wok long enkodim na givim aut long volium, taim 'read-feil reit i ken stat long go antap klostu long namba 3,000 kad, taim wanpela hevi bilong 'encoding' o 'antenna-tuning i kamap gen long olgeta hap. Long dispela taim, stretim i no wanpela 're-spec, em i wanpela 're-manufacture'. Dispela em i 'multiplier' we i hait bihain long liklik yunit prais long wanpela 'bulk key packet order'.

 

Wanem samting i save kamap long 'production floor' bilong mipela pastaim long ol i salim wanpela kad i go long sip

 

Dispela em i hap we planti saplaia insait long dispela kategori i no inap long toktok long en, bikos planti bilong ol i save salim gen ol kad we narapela man i bin kodim. 'Chip bonding' na 'encoding' em tupela step we ol hevi bilong 'compatibility' i save kamap planti taim, na tupela step we wanpela 'distributor' i no save luksave long en.

 

 

Mipela i ranim tupela insait long-haus.
