Sarudzo mbiri dzinonyatsoona Chengetedzo: Chip Giredhi uye Kukiya Kuenderana

 

Kana iyo packet yabva patafura sechinhu chekuchengetedza, kutenga kunodzika kune maviri akasiyana: chii chip chiri mukati mekadhi, uye kana iyo chip encoding inoenderana nekiyi yako yepuratifomu. Saflok, Onity, Dormakaba, uye masisitimu akafanana anotarisira zvishoma zvakasiyana data zvimiro pane kadhi.

 

 

Izvo zvinotaridzika zvidiki pane spec sheet. Apa ndipo payakamira kuita nhando kune one property. Batch ye500 makadhi akananga kuSoutheast Asia resort cheni akaverenga zvakakwana pamuverengi wedemo pabhenji redu: mwenje wegirini, kuverenga kwakakodzera, kadhi rega rega. Pasaiti, kadhi rega rega rakakanda "kadhi risingaite" pamusuwo. Mazuva maviri ekuongororwa kure akaitsvaga kune firmware yekuvandudza mugadziri wekiyi akange asundidzira ingangoita mwedzi mitatu yapfuura iyo yakashandura kuti chikamu cheki cheki chakasimbiswa; iyo encoding profil yatakapihwa yakatangira. Makadhi ezvitoro uye kudhinda zvakanga zvisina mhosva. Mikova yakanga isati yavhurika. Mukaha uripo pakati pe "kuverenga pabhenji" uye "kuvhura gonhi" ndipo chaipo panotadza kuodha kadhi rekiyi yehotera chinyararire.

 

Kugara kunotaura nyaya yakafanana, uye haufanirwe kuitora nekutenda; inoratidzwa mukurongedzerwazve kutenderera. Sechiyereso cheindasitiri chakaomarara, magineti-makadhi emitsetse anowanzoda kutsiviwa mukati memwedzi 6–12 yekuvhakacha kwevaenzi, ukuwo makadhi eRFID akadhindwa zvakanaka achiwanzoita makore 2–3 pasi pemutoro wakafanana. Mutengo{{7}pakadhi wega wega unofanirwa kudzokororwa katatu kazhinji haudhure; isarudzo yekubhadhara mari-kupfeka yuniti-inodhura.

 

Makiyi Makadhi eHotera anogadzirwa sei mumunda

 

Zvakakodzera kunzwisisa magadzirirwo, nekuti "makadhi eRFID anogona kugadzirwa" anotaurwa sechinhu chakapfava pasinasei,uyeseindizvo zvinokuudza kuti ndeapi makadhi ari panjodzi.

 

Nyaya yakare uye yakatekeshera yakanangana neMIFARE Classic's Crypto-1 cipher, yakadzokororwa nevaongorori vepaRadboud University kubvira muna 2008.IACR ePrint Archive). Makadhi pane iyo chip mhuri inosimbisa nehurongwa hwakaputswa pachena kweanopfuura makore gumi, zvakadaro, nekuti yakawanda yakaiswa hardware zvinoenderana nazvo, ichiri kutenderera pazvivakwa zvisina kumbokwidziridzwa.

 

Mhosva itsva uye isingazivikanwe yakaitika muna 2024: chip chakaburitswa chakanyatso kuvhara mapeji ekare ekuvhara (iyo FM11RF08S) yakave nekutakura hardware yayo-level flaw, zvichiita kuti munhu anorwisa ane maminetsi mashoma ekuwana kadhi rimwechete abudise makiyi ese enzvimbo (Nhau dzeHacker). The takeaway haisi "kudzivisa iyo imwe chip." Inyaya yekuti chip's marketing label ("upgraded," "encrypted," "next-generation") haitsivi yekutarisa nzira yayo yechokwadi. Makadhi asingavimbi nechinhu kunze kweiyo static kadhi ID, isina cryptographic exchange pakati pekadhi nekiyi, ndiwo ari nyore pane ese kutevedzera neyakachipa yezvigadzirwa hardware, chero kurongedza kunotaura. Kana skimming pamusuwo chiri chikamu chemodhi yako yekutyisidzira, ndiyo yakaparadzana spec line. A nhovoRFID-kuvharisa kadhi sleevekero dzekubira, kwete kuumba, uye vaviri vanovhiringidzika nguva dzose.

 

Kutsanangura Kadhi Rakachengeteka: AES, MIFARE Plus SL3, uye Mutual Authentication

 

Kugadzirisa hakuna kunetsa kana chip landscape yajeka, uye haina chekuita nekiyi pakiti inotumirwa nekadhi. Indasitiri iri kufamba kubva kuUID-chete uye Crypto-1 makadhi kuenda kumachipi vachishandisa AES-128 encryption ine mbiri yechokwadi: kadhi uye muverengi ega ega anoongorora imwe isati yawana chero ruzivo rwe data muverengi achinja mawoko, pane chero ID yekuwana data uchivimba.

 

Chip Type	Authentication Method	Cloning Resistance	Yakajairika Kushandisa Nyaya Nhasi
UID-chete / basic proximity	Static ID chete	Yakaderera kwazvo	Legacy, ichibviswa
MIFARE Classic (Crypto-1)	Proprietary cipher, yakaputswa kubva 2008	Low	Hombe yakaiswa base, upgrade candidate
MIFARE Plus SL3	AES-128, mutual authentication	High	Inoshanda yekusimudzira nzira yezvizhinji zvivakwa

AES-128 pari zvino iri kubatwa munzvimbo yese-inotonga indasitiri seisingagoneke kuita hutsinye-kumanikidzira nevatengi kana vezvekutengesa zvinhu, ndosaka MIFARE Plus SL3 yave nzvimbo yepakati pezvivakwa zvinotama kubva kuClass{10}zvikepe zvechinyakare pane kungosvetuka yakananga kuDESFire yakazara. Asi kurudziro iyi ine mamiriro ekuti vatengesi vazhinji havazosimudze panzvimbo yako: SL3 inobatsira chete kana yako yakaiswa makiyi 'firmware inotsigira kuiverenga padanho rekuchengetedza rauri kubhadharira. Iyo nzira yekusimbisa iyo haisi yekugamuchira chip dhairekitori; ndeyekukumbira kukiya yakanyorwa firmware version nhamba uye kuva nemuenzaniso kadhi rakaedzwa kupikisa firmware chaiyo usati wasaina. Kuodha makadhi eSL3 achipesana nemakiyi achiri kurongedzerwa eClass-level kuverenga inzira yakajairika mapurojekiti aya, uye kuchine yakakura kwazvo yakaiswa hwaro hwenhaka yeMIFARE Hardware mumunda kuchengetedza iko kukanganisa kuri nyore kuita. Apa ndipowo pane yakachengeteka hotera kiyi kadhi chirongwa uye kuenderanaRFID kiyi fobzvitupa ndezvemumwe fungidziro, saka vashandi uye mukana wevaenzi vanomhanya pane imwechete yakasimbiswa chip tier pane kadhi rakasimba rakapetwa nefob isina simba.

 

Zvikanganiso zvitatu zvekutenga zvinodhura kaviri

 

Mapatani mashoma anoratidza kazhinji zvakakwana kuyambukahotera kiyi kadhi odhakuti ivo vakakodzera kutumidza zvakananga, nekuti imwe neimwe inowanzo wanikwa chete mushure mekutumira makadhi.

Usabvume vimbiso yemuromo pano. Bvunza iyo chaiyo chip chikamu nhamba mukunyora uye firmware yakadhindwa-inopindirana bvunzo mhinduro uchienzanisa neyako chaiyo yekukiya modhi PO isati yaburitswa. Chechipiri ndechekugadzirisa kukiyi-kuenderana kwepuratifomu sedambudziko remutengesi rekugadzirisa mushure mechokwadi kwete kusimbiswa kusati kwagadzirwa. Ndizvo chaizvo zvinoita batch inoguma yakadhindwa nemazvo uye isingakwanise kuvhura gonhi rimwe chete. Chechitatu kufunga kuti nharembozha kana kuti foni{{6}kiyi yakavakirwa ipapo inochengetedzeka kupfuura kadhi remuviri; mukushandiswa kwazvino uno foni iri kutevedzera yakafanana yepasi chip credential, saka isina kusimba chip standard haina kusimba nekuda kwekuti inofungidzirwa pachiratidziro.

 

Heino chikonzero nei "akawanikwa mushure mekutumira" ndiyo inodhura chikamu, kongiri. Pa 5,000-makadhi ekumhanya, mazana mashoma ekutanga makadhi akatorwa pamvumo anoverenga zvakanaka; kutadza kuoneka kutozosvikira chivakwa chaiswa maencoding uye chabuda pavhoriyamu, apo kuverenga-mwero wekufoira uchikwanisa kutanga kukwira pane imwe nzvimbo kupfuura kadhi rechi3,000, kana imwe marginal encoding kana antenna{8}}tuning nyaya yadzokororwa mubatch yese. Panguva iyoyo kugadzirisa hakusi-kumwe, kugadzirazve. Ndiyo inowanza yakahwanda kuseri kwemutengo wakaderera weyuniti pane yakakura kiyi packet order.

 

Chii Chinoitika Pane Yedu Yekugadzira Floor Pamberi Kwekadhi Ngarava

 

Ichi ndicho chikamu vatengesi vazhinji vari muchikamu ichi havagone kutaura nacho, nekuti vazhinji vavo vanotengesa makadhi akavharidzirwa nemumwe munhu. Chip bonding uye encoding ndiwo nhanho mbiri uko matambudziko ekuenderana anowanzo tanga, uye matanho maviri emugovera kazhinji haana kuoneka mukati.

 

 

Tinomhanya tese mumba-.
