NXPMIFARE DESFire EV3 2K 4K 8K Ikarita

NXP MIFARE DESFire EV3 yerekana isonga ryikoranabuhanga ryikarita yubukorikori itagira aho ihurira, itanga umutekano utigeze ubaho, guhinduka, hamwe nibikorwa bya serivise zigezweho zo mumujyi hamwe no kugenzura porogaramu. Biboneka muri 2K, 4K, na 8K yibuka yibuka, aya makarita ya NFC atanga umutekano-urwego rwumushinga hamwe nuburyo bworoshye bwo gukora.

Incamake y'ibicuruzwa n'ibisobanuro bya tekiniki

Ikarita ya MIFARE DESFire EV3 ikora kuri 13.56MHz kandi ikagaragaza ubwihindurize buheruka mu muryango wa NXP uzwi cyane wa MIFARE DESFire. Aya makarita aranga:

• Amahitamo yo kwibuka: 2K, 4K, cyangwa 8K bytes
• Igenzura ryambere: Inkunga ya AES, DES, na 3DES
• ISO / IEC 14443 Kwubahiriza kugeza kurwego rwa 4
• Umuvuduko wo gucuruza: kugeza kuri 848 kbps
• Kubika amakuru: imyaka 25
• Andika kwihangana: 500.000 cycle

Bihujwe nibikorwa remezo bihari, aya makarita ya RFID agumana guhuza inyuma mugihe atangiza umutekano wongerewe umutekano.

Ibiranga umutekano wambere hamwe na Encryption

Umutekano uhagaze kumurongo wigishushanyo cya MIFARE DESFire EV3. Twubakiye ku rufatiro rukomeye rw'abayibanjirije (DESFire EV1 na EV2), EV3 ishyira mu bikorwa:

• Ibipimo rusange EAL5 + icyemezo
• Umutekano wihariye NFC (IZUBA) ibiranga ubutumwa
• Ibyuma bishingiye kuri AES
• Kugenzura hafi y'ibitero bya relay
• Gutezimbere kurinda ubuzima bwite binyuze muri UID uteganijwe

Ikarita yumutekano nibanga ryibanga ituma biba byiza kuri porogaramu z'umutekano zisaba kurinda ibitero bikomeye.

Inkunga nyinshi zo gusaba no guhinduka

Kimwe mubintu bikomeye biranga MIFARE DESFire EV3 igisubizo kitagira aho gihurira nubushobozi bwacyo bwo gushyigikira porogaramu nyinshi icyarimwe. Buri porogaramu irashobora:

• Komeza urufunguzo rwumutekano rutandukanye
• Kora wigenga
• Kohereza amakuru neza hagati ya porogaramu
• Shyigikira imiterere ya dosiye

Ibi bituma amakarita yubwenge atunganijwe neza kubikorwa byoherejwe aho ibyangombwa bimwe bikenera gukora intego nyinshi.

Gushyira mu bikorwa no gukoresha Imanza

Ikarita ya EV3 irusha izindi porogaramu zitandukanye:

• Uburyo bwo kwishyura abantu
• Kwinjira ibyangombwa byo kugenzura
• Serivise nziza yumujyi
• Ikarita yikigo
• Gahunda zubudahemuka
• Amatike ya elegitoroniki

Amashyirahamwe arashobora gukoresha amakarita kugirango azamure ibikorwa remezo byumutekano mugihe atezimbere uburambe bwabakoresha binyuze mubikorwa bidafite aho bihurira.

Inganda nubwishingizi bufite ireme

Ikarita yacu ya EV3 ihura nuburyo bukomeye bwo kugenzura ubuziranenge:

• Kubaka PVC kuramba
• Ubushyuhe bwo kwimura ubuso bushobora gusohoka
• Kwinjiza IC ukoresheje tekinoroji igezweho
• Kwipimisha 100% mbere yo kohereza
• Kuboneka mubipaki 100 cyangwa ingano yabigenewe

Buri karita ije ifite UID idasanzwe kandi yiteguye kohereza vuba muri sisitemu.

Gutegeka no Gushigikira Amakuru

Dutanga inkunga yuzuye kubicuruzwa byacu bya MIFARE DESFire EV3:

• Inyandiko ya tekiniki
• Ubuyobozi bwo gushyira mu bikorwa
• Kugabanya ibicuruzwa byinshi
• Amahitamo yoherezwa kwisi yose
• Ubufasha bwabandi

“MIFARE DESFire EV3 yerekana ejo hazaza h'ubucuruzi butagira umutekano. Ibikorwa byayo bigezweho ndetse n'umutekano ukomeye bituma uhitamo neza imikoreshereze igezweho yo mu mujyi. ” - Impuguke mu by'umutekano NXP

Inkunga y'abakiriya hamwe ninyandiko

Itsinda ryacu ryunganira ritanga:

• Ibisobanuro birambuye byibicuruzwa
• Amabwiriza yo gushyira mu bikorwa
• Kugisha inama tekinike
• Inkunga nyuma yo kugurisha
• Gutezimbere igisubizo

Kumakuru y'ibiciro no gutanga iperereza, nyamuneka hamagara itsinda ryacu ryo kugurisha cyangwa wuzuze urupapuro rwacu. Dutanga ibiciro byapiganwa kubintu bito kandi binini byateganijwe.

Imbonerahamwe: MIFARE DESFire EV3 Ikarita Ibisobanuro

Twandikire uyu munsi kugirango umenye uburyo amakarita ya MIFARE DESFire EV3 ashobora kuzamura ibikorwa remezo byumutekano wawe no kunoza porogaramu zidafite aho zihurira.
