NTAG na MIFARE NFC: uruhande -ku -uruhande ukugereranya

Iyi mbonerahamwe igereranya ibice ku bintu bikunda gufata ingingo y’umugambi.

 

Ubutandukane nyamukuru bugira ico bukoze ku mugambi wawe

 

Gusoma kuri telefone ngendanwa: iPhone, Android, NDEF na UID

Guhuza telefone si ikintu kimwe; bivana n’ico telefone isabwa gusoma. Ivyuma vyinshi vya iPhones na Android vy’ubu birasoma inyandiko ya NDEF ku kimenyetso ca NTAG kiri inyuma maze bikabikorako, bikafungura URL ata app ishizwemwo. Gusoma UID ya chip, canke gusoma amakuru y’umuce canke dosiye, ni igikorwa gitandukanye gikeneye kenshi app canke umusomyi yihariye.

Aha niho MIFARE Classic igira ingorane ku migambi y’abaguzi: amakuru yayo y’urwego ntashobora gusomwa neza kuri telefone zose, kandi ubufasha bwa iPhone cane cane buragabanutse, ni co gituma Classic akenshi ifatanywa n’abasomyi bitanga aho gukoreshwa na telefone za bose. NTAG na DESFire zikurikira ubwoko bw’ibimenyetso vy’ihuriro rya NFC, ivyo bikaba bituma bishobora kumenyekana. Nimba abakoresha bazokora ku matelefone yabo bwite, NTAG ni yo nzira itekanye kuruta, kandi irafasha gutahurauko gusoma NFC bikora kuri telefoneimbere y’uko ukora.

 

Umutekano n'ukwemeza

Ivyuma NTAG21x bimenyerewe bikoreshwa mu gukorana n’abantu. Bamwe bashigikira ijambobanga rya 32-bit rishobora guhagarika kwandika busanzwe, ariko ijambobanga si ukwemeza kw'ibanga, kandi UID ya chip, naho ari iyo kwihariza, irashobora gusomwa kandi ntabwo iri ku kimenyamenya cayo bwite c'ukuri. Ico ciyumviro ca nyuma kirahambaye, kuko UID-gusa "ugusuzuma" ni kimwe mu makosa asanzwe arwanya ukwihenda.

Kugira ngo umuntu yemeze vy’ukuri, iyo chip itegerezwa kwiyerekana mu buryo bw’ibanga.ADN ya NXP NTAG424ikoresha AES-128 kandi itanga kode itandukanye, server-ishobora kugenzurwa ku nzira yose, igoye cane gukora. Ku ruhande rwa sisitemu, MIFARE DESFire yongerako ivyemezo bitatu-vy'ukwemeza n'urugero rwa dosiye, rero ikarita n'umusomyi bigenzurana imbere y'uko amakuru yose yimuka. Ku bijanye n’ingene ivyo bishirwa mu ngiro, raba iyi nsiguro y’insiguro y’NFC irwanya-ubuhinga bwo kwigana.

 

Ububiko n'imiterere y'amakuru

NTAG ikoresha ubuhinga bwo kwibuka bworoshe, ahanini bushingiye ku murongo bwashizweho ku bwa NDEF, ni co gituma vyoroshe cane gushiramwo amakuru y'ama URL, inyandiko, n'amakuru y'abantu. MIFARE ikoresha ubwonko butunganijwe bw'imice, ibikorwa, amadosiye, n'imfunguruzo zo gushikamwo. Ivyo bituma umuntu ashobora kugenzura cane uwushobora gusoma canke kwandika iki, ivyo bikaba bishobora gutuma umuntu agira umugambi mwinshi, uburongozi bw’ingenzi be n’ukugerageza.

 

Ubufatanye bwa sisitemu n'igiciro

Umugambi wa NTAG ushobora gukoreshwa kenshi n’umuntu umweUmusomyi n'umwanditsi wa NFC: shiramwo URL, ushireko sticker, maze abakiriya bakore. Umugambi wa MIFARE akenshi ukeneye abasomyi bahuye, uburongozi bw’urufunguzo, porogarama y’inyuma, n’amategeko yo gushikamwo, hamwe n’ukugerageza kuri sisitemu y’ubuzima.

Igiciro gikurikira ivyo bigoranye. Igiciro nyaco c’igikoresho co gufatanya NFC ni ubwoko bw’igice, ubunini bw’antene, igikoresho (impapuro, PET, PVC, canke epoxy), gucapura, nimba ibimenyetso ari ubusa canke imbere y’-coded, intambwe iyo ari yo yose yo gutera canke gufunga, kandi, ku gukoresha ivyuma, umubare w’ivyuma wongereweko, vyose bigwijwe n’ingero. Impanuro ngirakamaro ni yoroshe: ntushireho ubugoyagoye bwa MIFARE igihe telefone ikeneye gusa gufungura URL, kandi ntugerageze gukoresha ubugenzuzi bw’ukwinjira butekanye ku gice ca NTAG c’ishimikiro.

 

NTAG424 ADN n'umuriro w'umuriro wo kurwanya-ukwihenda

Ku bijanye no kurinda ikimenyetso, iri ni ryo hitamwo rihambaye cane, kuko izo chips zompi zikoresha ubuhinga bukomeye bwa AES-128 ariko zitorera umuti ingorane zitandukanye gatoyi.

NTAG424 ADN ni intumbero-yubatswe kugira ngo abaguzi bakoreshe -kugira ngo -bagenzure. Kubera ko kode yayo yo kwemeza ivy’ukuri iterwa ku ntungamubiri yose kandi igasuzumwa kuri server yawe, umuguzi arashobora kwemeza ukuri akoresheje telefone isanzwe kandi ata porogarama, kandi iyo ntungamubiri nyene irashobora gutuma habaho ubudandaji canke kwiyandikisha. Ni kandi uburyo bwo gukoresha ubutunzi bwo kwemeza igicuruzwa c'umubare munini-.

MIFARE DESFire yubatswe ku bikorwa vyinshi-, umusomyi-ishingiye ku bidukikije nk'ugushikira, guca, n'agaciro kabitswe, kandi ni ihitamwo ryiza igihe icemezo gitekanye na co nyene gitegerezwa gukora izo kazi. Ku bijanye n’ugusuzuma ibintu vy’abaguzi vy’ukuri akenshi biraruta ivyo ukeneye; ku vyemezo bitegerezwa kuba mu buryo bwo kuronka canke bwo kwishura kandi bikaba bifise igikorwa co kwemeza, birahuye neza.

Ingingo mu murongo umwe: guhitamwo NTAG424 ADN ku baguzi-bahanganye n'uburinzi bw'ibara, na DESFire igihe kwemeza bitegerezwa kubana n'ugushikira, gutanga amatike, canke kwishura muri sisitemu imwe icungiwe. Uko biri kwose, ntimwizigire igenzura rya UID ryoroshe, kuko ivyo ni ukumenya, si ukumenya.

 

Guhitamwo hakurikijwe ugusaba

Kuberaamasekeza yo kwamamaza n'amafoto y'ubwenge, NTAG213 ikoresha tap-ku-ugufungura URLs, gukuraho porogaramu, n'amapaji y'isekeza ku giciro gito kandi cizewe. Kuberagupfunyika neza n'amakuru y'ibicuruzwank’ibitabu, ukwandikisha garanti, n’ibirimwo vy’ibara, NTAG213 ipfuka amahuzu y’ishimikiro, na NTAG216 iyo ukeneye ivyumba vyinshi.

Kuberakwemeza igicuruzwa no kurwanya-ukwigana, ukoreshe NTAG424 ADN, canke DESFire imbere muri sisitemu nini itekanye, kandi ntukigere ukoresha igice ca URL gihagaze-wonyene. Kuberakugenzura ukwinjirank’inzugi, indangamuntu y’umukozi, ivyumba vy’amahoteli, n’ahantu habujijwe, MIFARE DESFire canke igice gihuye n’uburyo busanzwe ni co gisanzwe, akenshi gitangwa nk’amakarata canke amafobe aho gutangwa nk’ibimenyetso. Kuberagutanga amatike, kuba umunyamuryango, n'ibindi birori, MIFARE ni co gisanzwe gibereye, kandi icemezo c’uburenganzira ni kenshi .Umukanda wo ku maboko wa RFIDcanke ikarata aho gushiramwo ikimenyetso. Kuberaikimenyetso c'umutungo woroshe, NTAG213 ni nk’aho bihagije kiretse iyo sisitemu itegetse ko habaho igice ca MIFARE.

 

Igihe co kudakoresha NTAG, n'igihe co kudakoresha MIFARE

Irinde NTAGiyo ukeneye ubugenzuzi bw'ukwinjira kw'ibanga, agaciro kabitswe canke kwishura, ivyemezo vyinshi-bicungiwe, canke uburenganzira bwiza-bw'inyuma. Uwo niwo muce wa DESFire.

Irinde MIFARE, cane cane Classic, iyo intumbero ari telefone yoroshe, nini-gukora kuri -to -URL, iyo abakwumviriza bari cane kuri iPhones kandi woba wizigiye gusoma umuce wa Classic, canke iyo ushaka igiciro gitoyi cane n'ugushiramwo amakuru yoroshe cane. Muri ivyo bihe NTAG iranyaruka, irahenda, kandi irashobora gutegekanirwa.
