MIFARE DESFire EV2 2K 4K 8K Ikarita ya RFID Ikarita
MIFARE DESFire EV2 2K 4K 8K Ikarita ya RFID yerekana isonga rya tekinoroji yubukorikori idafite aho ihuriye.
Gutanga umutekano urenze kandi uhindagurika, ibyo bicuruzwa bya NXP MIFARE bitanga umutekano-urwego rwumushinga hamwe nubushobozi bwo kwishyira hamwe muburyo bwo kugenzura uburyo bugezweho bwo kugenzura no gukoresha umujyi wubwenge. Muri iyi ngingo, tuzacukumbura ibiranga, inyungu,
na tekinike yihariye ya MIFARE DESFire EV2, itanga ubuyobozi bwuzuye kubakoresha.
Incamake y'ibicuruzwa ninyungu
MIFARE DESFire EV2 ikora kuri 13.56MHz kandi ikaba yujuje ubuziranenge bwo hejuru.
Iraboneka muburyo butatu bwo kwibuka: 2K, 4K, na 8K bytes, byita kubikenewe bitandukanye.
Ikarita yambere yo gushishoza hamwe nibiranga umutekano bikomeye bituma iba nziza kubisabwa bisaba kurinda amakuru yo mu rwego rwo hejuru.
Inyungu z'ingenzi
- Umutekano wongerewe imbaraga: Hamwe nuburyo bugezweho bwo gushishoza nka DES, 2K3DES, 3K3DES, na AES, MIFARE DESFire EV2 itanga amakuru neza kandi ikabikwa.
- Guhinduranya: Birakwiriye muburyo butandukanye bwo gusaba, harimo kugenzura uburyo bwo kugenzura, gutwara abantu, e-kwishyura, hamwe na gahunda zubudahemuka.
- Kwishyira hamwe: Kuzuza byuzuye ISO14443-A na NFC Ubwoko bwa 4, byemeza guhuza nibikorwa remezo byabasomyi ba NFC.
- Imikorere ihanitse: Igipimo cyihuta cyo kohereza amakuru hamwe nubushobozi buke bwo kwibuka bituma biba byiza kubidukikije.
Urucacagu rw'ibicuruzwa
1. Ibiranga umutekano wambere
Umutekano ningenzi mugushushanya MIFARE DESFire EV2.
Ikarita ikubiyemo ibyuma bishingiye kuri moteri ya kriptografiya, ubwumvikane-butatu bwo kwemeza,
n'umutekano wohereza amakuru protocole. Ifite kandi Ibipimo Rusange EAL5 + icyemezo cyumutekano,
kwemeza urwego rwo hejuru rwo kurinda ibitero bikomeye.
2. Amahitamo yo kwibuka: 2K, 4K, na 8K
MIFARE DESFire EV2 iraboneka muburyo butatu bwo kwibuka: 2K, 4K, na 8K bytes. Ihinduka ryemerera abakoresha guhitamo ubushobozi bukwiye bwo kubika kubyo bakeneye byihariye, haba kubigenzura byoroshye cyangwa sisitemu igoye ya sisitemu nyinshi.
3. Kubahiriza ISO14443-A na NFC Ubwoko bwa 4
Ikarita yujuje byimazeyo ISO14443-A na NFC Ubwoko bwa 4, bigatuma ihuza nabasomyi benshi ba NFC nibikorwa remezo. Ibi bituma habaho kwishyira hamwe no gukorana na sisitemu zigezweho.
4. Igipimo cyihuse cyo kohereza amakuru
MIFARE DESFire EV2 ishyigikira igipimo cyo kohereza amakuru agera kuri 848 kbps, itanga itumanaho ryihuse kandi neza hagati yikarita numusomyi. Ibi nibyingenzi mubisabwa bisaba gutunganya amakuru byihuse no kwinjiza byinshi.
5. Igishushanyo gikomeye kandi kirambye
Ikarita yagenewe guhangana n’ibidukikije bikaze no gukoreshwa kenshi. Itanga amakuru yo kubika amakuru yimyaka 25 hamwe no kwihanganira kwandika 500.000 cycle, bigatuma ihitamo kwizerwa kubisabwa igihe kirekire.
6. Inkunga-Porogaramu nyinshi
MIFARE DESFire EV2 ishyigikira porogaramu nyinshi kurikarita imwe, bitewe nuburyo bwimiterere ya dosiye nubushobozi bwo kuyobora porogaramu. Ibi bituma biba byiza kubikorwa byumujyi byubwenge, aho ikarita imwe ishobora gukoreshwa mumodoka rusange, kugenzura uburyo, e-kwishyura, nibindi byinshi.

Amabwiriza yo gukoresha
Kugira ngo ukoreshe MIFARE DESFire EV2, gusa werekane ikarita kumusomyi uhuza NFC. Ikarita yambere yumutekano yikarita izakemura ibyemezo no kohereza amakuru, bizane itumanaho ryizewe kandi neza.
Ingaruka ku bidukikije
MIFARE DESFire EV2 yateguwe hamwe no gukomeza kuramba. Ikarita ndende yigihe kirekire kandi iramba bigabanya gukenera gusimburwa kenshi, kugabanya imyanda. Byongeye kandi, ubwitange bwa NXP mubikorwa byogukora ibidukikije byangiza ibidukikije byemeza ko umusaruro wamakarita ugira ingaruka nke kubidukikije.
Isubiramo ry'abakiriya
Abakiriya bashimye MIFARE DESFire EV2 kubera kwizerwa, umutekano, no guhuza byinshi. Abakoresha benshi bagaragaje ikarita yihuta yo kohereza amakuru kandi nta nkomyi
Andika ubutumwa bwawe hano hanyuma utwohereze
