To use secure DESFire EV2 secure messaging, you must enable EV2 authentication on your DESFire configuration files and export them to your workstations and Synergis™ units.
Configure MIFARE DESFire
in Security Center and export your configuration to an XML
file.
The DESFire configuration file (SmartCardsSites.xml) is created in
Config Tool using the MIFARE DESFire
configuration task. At the moment, this task does not support the EV2
authentication mode. Therefore, you need to change this setting in the exported XML file
manually.
