 * Asynchronous CPU core
 * (3) DES coprocessor
 * Fixed Command Set
 * No Customer ROM codes

The Mifare DESFire file-system is able to handle:


 * up to 28 application / card
 * up to 16 files / application
 * up to 14 keys / application
 * 1 master-key for card maintenance
 * Plain, (3)DES encrypted, or MAC-ed data transmission
 * On-Chip Backup management

This section presents an authentication procedure specific to Mifare DESFire tags/cards that have certain particularities and requirements. An improved procedure should be sufficient for RFID tags/cards authentication and it is presented as Java source code statements for non-sensitive operations (the complete source code may be obtained from the authors):
