Desfire file data
Desfire cards are fully supported, including DESFIRE EV1/EV2 cards with 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 its 3-byte application identifier (AID). Each application
may contain up to 32 files.
Specify the following parameters;
Application ID
Three-byte application identifier (AID). For example; F12345.
File number
File number in the range from 0 to 31.
Communication mode
File communication mode. This can be either;
•
Plain
•
Plain secured by MACing
•
Fully enciphered
Data length
Number of data bytes to read. The maximum number of bytes depends upon operating-mode and frame-length.
Data offset
Number of data bytes to skip.
Encryption
Authentication method. Select one of below options;
•
None (skip authentication)
•
Native DES/3DES
•
ISO DES/3DES
•
3 Key 3DES
•
AES
Key number
