MIFARE yog ib tsev neeg ntawm cov khoom lag luam tsis sib cuag ntse tsim los ntawm NXP Semiconductors.
MIFARE phaib muaj nyob rau hauv ntau hom thiab muaj peev xwm khaws cia, suav nrog MIFARE Classic 1K thiab MIFARE Classic 4K.
MIFARE Classic 1K daim npav muaj lub cim xeeb muaj peev xwm ntawm 1 kilobyte (1024 bytes), thaum MIFARE Classic 4K daim npav muaj peev xwm nco txog 4 kilobytes (4096 bytes).
Muaj lwm hom MIFARE phaib uas muaj peev xwm khaws cia sib txawv thiab nta. Nov yog qee qhov piv txwv:
- MIFARE Ultralight: Hom MIFARE daim npav no muaj peev xwm nco tau ntawm 512 cov khoom (64 bytes) thiab feem ntau yog siv rau cov nqi qis, cov ntawv ntim siab xws li daim pib thiab kev thauj mus los.
- MIFARE Plus: Qhov no yog qhov kev nyab xeeb dua ntawm daim npav MIFARE Classic, nrog cov yam ntxwv xws li AES encryption thiab kev sib koom ua ke. Nws muaj nyob rau hauv 2K thiab 4K nco muaj peev xwm.
- MIFARE DESFire: Qhov no yog daim npav MIFARE muaj kev nyab xeeb siab uas txhawb nqa cov txheej txheem encryption qib siab thiab ntau daim ntawv teev npe (AIDs). Nws muaj nyob rau hauv ntau lub cim xeeb, xws li 2KB txog 8KB.
- MIFARE SAM (Secure Access Module): Qhov no yog ib qho kev ruaj ntseg cais uas tuaj yeem siv nrog MIFARE phaib los txhim kho lawv cov yam ntxwv kev ruaj ntseg. Nws muab kev ruaj ntseg tseem ceeb cia thiab cryptographic ua haujlwm rau MIFARE-based systems.
