Ikarita ya Mifare | NXP MIFARE DESFire® EV1 2k

Ikarita ya MIFARE DESFire EV1 2K (D21), igicuruzwa cyo mu rwego rwo hejuru mu makarita adahuza, gikora kuri 13.56 MHz. Irakurikiza ibipimo bya ISO 14443A mugihe protocole yayo yo gutwara ihuza na ISO 14443-4.

Kurata 2K byte itangaje yibuka idahindagurika (NVM), ifite ibikoresho byihuta byihuta-bitatu-DES data encryption co-processor. Iyi karita kandi yishima kumurongo wibikorwa byinshi byo kwibuka hamwe nuburyo buyobora inganda, uburyo bwa 3-bwo kwemeza. Hamwe numubare udasanzwe utanga numero idasanzwe hamwe nigikoresho cyihariye cyo kurwanya amarira kugirango umenye umutekano wamakuru mugihe cyogukoresha mudasobwa, ikarita ya MIFARE DESFire EV1 ije ifite gusoma-hafi ya 10cm, bitewe nimbaraga zitangwa nabasomyi.

Ikarita ya Mifare | NXP MIFARE DESFire EV1 2K

Byashizweho mbere na mbere gutanga ibisubizo bitagira aho bihurira na serivisi zitwara abantu hamwe na gahunda zuzuzanya,

ikarita ya MIFARE DESFire EV1 irashobora gusobanura uburyo ucunga amakuru.

Hano hari ibintu bitatu byiyongera bituma ikarita ya MIFARE DESFire EV1 igaragara:

1.Igenamigambi Ryinshi: Byihuta-byihuta-bitatu-DES data encryption co-processor itanga umutekano wamakuru cyane, bigatuma biba byiza kubikorwa byoroshye.

2.Impinduka zisomwa-Urutonde: Ukurikije imbaraga zitangwa nabasomyi, ikarita ikora intera ishimishije igera kuri 10cm, itanga ibintu byinshi mubikorwa bitandukanye.

3.Kuzamura Data Ubunyangamugayo: Hamwe nuburyo bwihariye bwo kurwanya amarira, isezeranya ubunyangamugayo bukomeye ndetse no mugihe cyoguhuza amakuru, bigatuma amakuru yizewe kandi yizewe.

Ukurikije amahame afunguye kwisi yose kuri interineti ya RF hamwe nuburyo bwo gutondeka amakuru, umuryango wibicuruzwa bya MIFARE DESFire bitanga microcontroller ishingiye kuri IC. Izina ryayo DESFire ryerekeza ku ikoreshwa rya DES, 2K3DES, 3K3DES, na AES ibyuma bifata ibyuma bifata amajwi kugirango babone amakuru yoherejwe.Uyu muryango urakwiriye cyane kubateza imbere ibisubizo hamwe nabashinzwe sisitemu yubaka ibisubizo byizewe, bikorana, kandi binini cyane bitagira ibisubizo. MIFARE DESFire ibicuruzwa birashobora kwinjizwa muri gahunda igendanwa kandi bigashyigikira ibisubizo byinshi byikarita yubwenge ikoresheje indangamuntu, kugenzura uburyo, ubudahemuka, hamwe na micropayment, ndetse no mubitike byo gutwara abantu.

Imigaragarire ya RF: ISO / IEC 14443 Ubwoko A.

Imigaragarire idafite aho ihuriye na ISO / IEC 14443-2 / 3 A.
Hmin nkeya ituma intera ikora igera kuri mm 100 (bitewe nimbaraga zitangwa na PCD na antenna geometrie)
