Umutekano ni inshingano yo ku rwego rwa sisitemu-, si gusa ibisobanuro vy'igice.

Gusaba gukora vyinshi imbere yo kugerageza

Igihe cose wemeze amakarata nyayo, abasomyi, porogaramu nkuru, porogarama n’ugushiramwo amakuru imbere y’uko wiyemeza gukora ibintu vyinshi.

MIFARE canke NTAG: Mu vy’ukuri Urakeneye MIFARE?

Si umugambi wose wa 13.56 MHz mu vy’ukuri ari ingorane yo guhitamwo MIFARE.

Nimba intumbero nyamukuru ari ugukorana n’abaguzi kuri telefone ngendanwa, nk’ugufungura URL, gusangira urutonde rw’ibintu, gutanguza urupapuro rwo gusubiramwo canke gutuma igikorwa coroshe ca NFC, igicuruzwa kiva kuIkimenyetso ca NFCurutonde rushobora kuba ari rwo rubereye kuruta.

Nk'akarorero, porogaramu yoroshe ya telefone ngendanwa-ishobora gukoreshaNTAG213 ikarita ya NFCaho gukoresha uburenganzira bwo gushika kuri MIFARE butekanye.

MIFARE irarushiriza kuba ngirakamaro iyo sisitemu irimwo ukuronka uburenganzira bugenzurwa, abasomyi bitanga, kwemeza, gutanga amatike, agaciro kabitswe canke ibikorwa vy'amakarata y'ubwenge-.

Ikibazo ciza kuruta si iki:

Ni ikihe gice ca RFID ciza kuruta ibindi vyose?

Ni vyo:

Ni iyihe chip ihuye n’ikoreshwa, umusomyi, ibisabwa mu bijanye n’umutekano, ubuhinga bwo kwubaka n’ubuzima bw’ivyemezo?

Ni igiki ukwiye kohereza uwuguha RFID imbere y’uko usaba igiciro?

Uwugurisha arashobora gutanga impanuro ibereye kuruta iyo ibisabwa mu vy’ubuhinga bitomoye.

Tegura amakuru akurikira:

1. Gusaba:ukwinjira, amatike, hoteli, gutwara, ubudahemuka, ubunyamuryango canke ukundi gukoresha
2. Ubu umusomyi akora n'akarorero:niba iyo sisitemu isanzwe iriho
3. Ikarata canke ikigereranyo c'ubu:cane cane ku migambi yo gusubirira canke kwimuka
4. Urugero rw'umutekano rusabwa:harimwo n'ivyo bitera ubwoba iyo sisitemu itegerezwa gutorera umuti
5. Amakuru asabwa:ivyo mu vy'ukuri bikeneye kubikwa ku vyemezo
6. Imiterere y'ibisabwa:ubusabe bumwe canke bwinshi
7. Ibisabwa kuri telefone ngendanwa:nimba ubufatanye bwa NFC bukenewe
8. Uburyo bw'umubiri:ikarita, umukanda wo ku maboko, urufunguzo, itike canke ikindi cemezo
9. Ubuzima bwitezwe:umusi umwe, amezi menshi canke imyaka myinshi
10. Igitigiri:Ubwinshi bw'akarorero n'ubwinshi bw'umusaruro witezwe
11. Kugira umuntu ku giti ciwe:gucapura, gukoresha UID, gushiramwo amakuru canke ibindi bisabwa
12. Igerageza:umusomyi n'ukwemeza porogaramu bisabwa imbere yo gukora

Niba udashobora gutanga ikigereranyo nyaco c’igice, wohereze ivyerekanwa vy’ivyemezo biriho hamwe n’ibisobanuro vy’umusomyi n’ivya sisitemu aho gutekereza ku kuntu bisa.

Urutonde rwa nyuma rw'abahisemwo MIFARE

• Sigura igikorwa imbere yo guhitamwo igice.
• Sigura ingeramizi nyayo y'umutekano aho gukoresha ijambo "umutekano" nk'igisabwa rusangi.
• Wemeze neza umusomyi, mudasobwa n'ibidukikije vya mudasobwa.
• Raba amakuru mu vy’ukuri akeneye kubikwa.
• Fata ingingo nimba bisabwa gusaba rimwe canke menshi.
• Wemeze nimba ugukorana na NFC ya telefone ngendanwa ari ngirakamaro.
• Ihuza IC n’ubuzima bw’ivyemezo n’imiterere y’umubiri.
• Gereranya igiciro cose ca sisitemu, atari igiciro ca chip gusa.
• Itandukanya ibisabwa vyo guhuza iragi n'ibisabwa vya sisitemu nshasha-.
• Gerageza ivyerekanwa vy’ukuri imbere y’uko ukora vyinshi.

Nimba uriko urakora urutonde rushasha, ntuhitemwo ivyemezo vy’ukwemeza wenyene.

Niba uriko urasubiramwo ubuhinga busanzweho, tangura n’ibisabwa vyo guhuza n’ivyo kwimuka.

Kandi nimba utaramenya neza hagati ya MIFARE Classic, Plus, DESFire, Ultralight canke iyindi IC idakorana n’abantu, banza uhe uwuguha ibikoresho igishushanyo c’umusomyi wawe, ivyemezo vy’ubu, ibisabwa vyo gukoresha n’umutekano. Ivyo bintu birakenewe cane kuruta gusaba gusa "igice ciza ca MIFARE."
