READING MIFARE DESFIRE FILE DATA
The MIFARE DESFIRE cards are fully supported. Also other newer DESFIRE EV1 cards can be used. Including the
DES, 3DES, 3 Key 3DES and AES encryptions.
The DESFIRE card's memory is organized using a flexible file system. This file system allows several different
applications on a single card. Every application is identified by it's 3 byte application identifier (AID). Each
application may contain up to 32 files.
Upon configuring the smartcard-booster for reading MIFARE DESFIRE cards, the following parameters must be
specified.
Application ID
Three byte application identifier (AID).
File number
File number in the range from 0 .. 31.
Communication mode
Plain.
Plain secured by MACing.
Fully enciphered.
Data Length
Number of bytes to transmit. The maximum number of bytes is dependant upon the operating-mode and
frame-length settings.
Data Offset
Number of bytes to skip.
Encryption
None (skip authentication)
Native DES/3DES
ISO DES/3DES
3 Key 3DES
AES
Key number
Key number in range from 0 to 13.
Key
Security authentication key. Depending upon the selected encryption method and key number. The
encryption key is 16 or 24 bytes.
