Ukukhetha ibheji yoFikelelo yeRFID: Izigqibo eziNgemva koKhuseleko, ukuNcoma, kunye neNdleko yokwenyani

Oku kubhaliwe ukusuka kwicala lebhentshi eyenza ikhadi, kungekhona isofthiwe eyifundayo. Kuzo zonke ii-odolo esiziqhubayo, izigqibo ezithathu ezifanayo (ukhuseleko lwetshiphu, ukuhambelana kwefomathi, kunye neendleko zomjikelo wobomi) zizo ezo ezahlula ukuthunyelwa okwenziwa kucocekile kwenye ejikela kushicilelo kwakhona.

 

"Ibheji yeKhadi," "iKhadi leProx," "iNkcazelo yoFikelelo": Into enye, amaNqanaba oMngcipheko amaThathu ahluke kakhulu

 

Ndwendwela amaziko alishumi kwaye uxande olunye lweplastiki lubizwa ngamagama amahlanu ahlukeneyo. Kufikelelo-kumxholo wolawulo, ibheji yekhadi likhadi lesazisi elinetshiphu yeRFID efakwe ngaphakathi kunye ne-eriyali eyenza imisebenzi emibini ngaxeshanye: ibonisa ubuso negama emntwini, kwaye iphendula umfundi emnyango. Ibheji yindlela enye kuphela enokuthatyathwa yisiqinisekiso. IiFobs, ii-wristbands, kunye ne-wallets zefowuni zezinye, kwaye okwenene{4}ukusasazwa kwehlabathi kudla ngokuxuba ezimbalwa zazo phantsi komgaqo-nkqubo wofikelelo omnye, indlela iindawo ezinkulu esele zidibanisa ngayo iipasi eziprintiweyo ezineebhanti ezitshijiweyo zewristbands.ukungena okuphuculweyo kumasango amaninzi.

Ukuxhawulana{0}Isandla Ezintathu Ngasemva kwempompo nganye

 

Indlela esebenza ngayo ibheji ye-RFID imfutshane ngokwaneleyo ukuba ingatsho ngomoya omnye. Ikhadi liphethe itshiphu enesichongi esisodwa kunye ne-eriyali. Umfundi osemnyango ukhupha ibala lerediyo; i-eriyali yekhadi ivuna amandla aneleyo okuvusa itshiphu kwaye ithumele inombolo yayo kwakhona; umfundi ugqithisa elo nani kumlawuli, olijonga kuluhlu kwaye enze isigqibo sokukhulula isitshixo. Utshintshiselwano lonke lugqiba kakuhle phantsi kwesibini, kungabikho uqhagamshelwano kwaye akukho bhetri ekhadini.

 

Loo modeli yebheji yesazisi sokungaqhagamshelwanga ngoku ayigqibekanga ngesizathu esinokumetwa. Ngo-2025, i-RFID kunye ne-NFC kunye zibambe i-57.75% yofikelelo-lolawulo loqhagamshelo-isabelo sobuchwephesha, phambi kwayo yonke inketho entsha engenazingcingo (Mordor Intelligence).

 

 

Umbuzo woKhuseleko uninzi lwabathengi batsiba kude kube semva kokwaphulwa komthetho

 

Nasi isiphelo uninzi lwamaqela okuthenga lufike emva kwexesha kakhulu: ibheji esezantsi-yesiqhelo 125 kHz inika ukhuseleko malunga nokukopa. Isasaza inani elimiselweyo ngokucacileyo, kwaye elo nani lingabanjwa liphinde libhalwe kwindawo engenanto ngesixhobo esixabisa ngaphantsi kweedola ezingamashumi amabini kwaye akukho buchule bokusebenza. Self-i-kiosks zenkonzo kwezinye iikhonkco zokuthengisa ngoku zizakuphinda-phinda ikhadi le-prox ngendlela ivenkile yehardware esisika ngayo isitshixo (CampusIDNews).

 

Yintoni idemo ye-cloning engazange ibonise ngayo isiphelo sangasemva. Xa ikhadi lofikelelo likhutshelwe, inkqubo ifunda isiqinisekiso esisebenzayo kwaye ifaka ingeniso phantsi komnini osemthethweni, ngoko ke umkhondo wophicotho-zincwadi uthe cwaka uba yintsomi kwaye umnini-khadi wokwenyani akanakungqina ukuba bebengekho apho ilogi ithi bebekho. Usoyikiso alufane lube ngumntu wangaphandle ogqunyiweyo, nokuba; umntu onemizuzwana engamashumi amathathu yokufikelela kwikhadi elikufutshane elingafihlwanga udla ngokuba ngumsebenzi ohambayo, ixesha elithile, okanye unokontraka. Olo mva-lokutyhileka kwesiphelo sisizathu sokuba singayi kuthumela ngenqanawa isambuku esikhulu esingacwangciswanga-phezulu ngaphandle kothotho-ukuya-ukukhutshwa kwerekhodi kwifayile - ikhadi elingalandelwanga elifakwe kwinkqubo ephilayo liba sitshixo esisisigxina akukho mntu unokuphendula emva kwenyani.

 

I-LF, i-HF, okanye iKhadi le-Smart elifihliweyo: Tshatisa iChip kwisisongelo, hayi iNcwadana.

 

Ukuphindaphinda kulapho uninzi lwamaphepha especc ayeka khona kwaye uninzi lweempazamo zokuthenga ziqala. Uthelekiso olunyanisekileyo alukho "phantsi ngokuchasene nokuphakama" kodwa "yintoni echasayo ukukopa ngokuchasene noko kungenjalo."

Umgibe ongaphakathi kuloo tafile ngumqolo wesibini. Uninzi lwababoneleli basaphendula "ngaba ikhuselekile?" nge "ewe, yi-13.56 MHz," ngokungathi i-frequency yayilukhuselo. Akunjalo. I-MIFARE Classic ihambise ikhadi kwifrikhwensi ephezulu kodwa yathumela i-cipher esele iqhekeziwe kwaye ivuleleke kuhlaselo lwesitshixo esisebenzayo{4}}Ukhuseleko loLwazi lweBlack Hills). Ngoko ke imeko ekufanele ukuba uyibambe kwincoko yokukhangela ayicacanga: ukuba umthengisi ucaphula iMIFARE Classic kwaye uyichaza njengophuculo lokhuseleko, yiphathe njengempendulo engafanelekiyo, hayi indawo yothethathethwano. Ukukhuseleka namhlanje kuthetha ukuba i-encrypted smart{2}}iintsapho zamakhadi ezinobungqina bokwenyani, kwaye indawo yokuhlala i-chip ihlala kwimiba, kuba isiqinisekiso esisindileyo kwiminyaka emihlanu yeepokotho kunye nebheji reel yileyoimathiriyeli yakhethwa kuluhlu lokufunda kunye nobomi, hayi ixabiso leyunithi.

 

Umgibe wokuNxibelelana owenza izitena uMyalelo weKhadi oLungileyo ngokugqibeleleyo

Ungathenga eyona bheji ikhuselekileyo ye-RFID yofikelelo kwimarike kwaye usenokusilela ukuvula umnyango ekufikeni kwakho. Le yimowudi yokusilela eyothusayo kuqala-ixesha kunye nokuphinda abathengi ngokufanayo, kwaye ayinanto yakwenza netshiphu. Inento yokwenza nendlela inombolo yekhadi epakishwa ngayo kwaye ngawaphi amanani axelelwe ukuba umfundi makawathembe.

 

Iingcamango ezimbini zenza umonakalo omkhulu. Eyokuqala kukuba ifomathi ayilo nani. Ifomathi encinci yekhadi ichaza indlela idatha yayo ebekwe kwaye ifundwe ngayo, kwaye ngaphaya komgangatho we-26-bit endala kunokubakho iifomati ezininzi ezahlukeneyo ezabelana ngobude obufanayo, nganye ibeka ikhowudi yoncedo kunye nenombolo yekhadi kwiindawo ezahlukeneyo. Eyesibini yikhowudi yoncedo ngokwayo, isazisi ekwabelwana ngaso esidibanisa ibhetshi yamakhadi. Abafundi kunye nabalawuli bahlala becwangciswa ukuba bamkele ikhowudi enye yoncedo, ngoko ke ulungelelwaniso olugqibeleleyo ngokobuchwephesha olunekhowudi yoncedo olungalunganga alubonakali kwisistim.

 

Indlela edlala ngayo ixhomekeke ngokupheleleyo kwindawo ohlala kuyo:

 

Imeko A

Kwindawo enye-ekwakhiweni kwendawo eluhlaza, unobunewunewu bokukhetha ifomathi enye kunye nekhowudi enye yoncedo kunye nokubhala zombini. Umngcipheko uphantsi logama nje umntu ewubhala phantsi.

 

Imeko B

Kwisiza -esininzi okanye ukusasazwa okwandisiweyo, ifomathi eqhelekileyo ye-26-bit iba lityala, kuba ikhowudi yayo ye-8-bit (0–255) kunye nenombolo ye-16-bit yekhadi (ukuya kuma-65,535) ibeka isithuba esisebenzisekayo malunga ne-16.7 yezigidi zee-ID ezizodwa (ngeSIA 26-bit ye-bitation ye-bit), ekugqibeleni ikhusi ikhowudi ye-Wiegand kwifomathi enye iya kukhupha ikhowudi ye-Wiegand enye indawo inani. Imihlaba emikhulu ifuna iifomati ezongeziweyo ezichazwe ngaphambili.

 

Imeko C

Kwi-reorder yenkqubo esele ikhona, intshukumo ekhuselekileyo kuphela kukutshatisa ifomathi echanekileyo kunye nekhowudi yoncedo esele ikwintsimi, nto leyo ethetha ukuzazi ngaphambi kokuba ucele isicatshulwa kunokuba uzibhaqe emva kokuba amakhadi engafundi. Kukho umahluko onxulumeneyo uninzi lwababoneleli abayi kuphakamisa ngokwabo: ikhonkco phakathi komfundi kunye nomlawuli. I-Standard Wiegand i-Standard Wiegand yindlela enye kwaye ayifihlwanga, ngoko ke inombolo yebheji ehamba kulo mgca inokubanjwa kwaye iphinde idlale, yiyo loo nto ukufakwa okutsha kuhanjiswa kumgangatho we-OSDP we-bidirectional. Akukho nanye ekwikhadi, kodwa yonke into ithatha isigqibo sokuba ingaba ikhadi oliodolileyo liyasebenza na.

 

Iindleko zeBhaji yokuFikelela kubo bonke ubomi balo

 

Ixabiso{{0}ngekhadi ngalinye lelona nani lincinci kwisigqibo. Ixabiso lokwenyani lenkcazi lixabiso leyunithi kunye nayo yonke into eyenzekayo emva koko: ukukhupha amakhadi alahlekileyo naphukileyo, ukuvala abaqhubi abahambileyo, kunye nosuku oluduru ngamathuba athile xa ifomathi okanye indawo{2}}ukungafani kwekhowudi kunyanzelisa ukuodolwa ngokutsha kunye notyelelo lwesayithi. Inkqubo ejongeka inexabiso eliphantsi kumgca womgca inokuchitha uninzi lwebhajethi yayo kwi-churn, yiyo loo nto kanye umzekelo osetyenzisiweyo kuluhlu lwethu.iyonke-indleko{1}}{2}}yobunini bencwadi yokudlala yeenkqubo zamakhadi ehoteleilandelela ikhadi lonyaka lokukhwela ibhayisekile kunesincamathelisi.

Beka inani kolona guqulelo lubi lwaloo churn. Xa i-250-ipiece top-yaliwayo ngenxa yokuba ikhowudi yoncedo ayihambelani noko kulindelwe ngabafundi ebaleni, ixabiso elifunyenweyo lalo makhadi lidla ngokuphinda kathathu ukuya kwesihlanu ngexabiso loqobo{4}}ngexabiso leyunithi xa uphinda wongeza ushicilelo, umfundi kwakhona{6}}ukwenza iparamitha, kunye nondwendwelo lochwephesha alufundele umsebenzi. Kumava ethu olo hlobo lolawulo lokufikelela kwikhadi lokuphinda-odole amaqela angaphumeleliyo phantse ngokupheleleyo kwi-top-ups ebekwe ngaphandle kokuqinisekisa ifomathi ekhoyo kuqala, yiyo loo nto esona sicatshulwa sisezantsi kunye neendleko zomjikelo wobomi eziphantsi azifane zifane nocwangco.
