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™ Cloud Link units.

Before you begin

Configure MIFARE DESFire in Security Center and export your configuration to an XML file.

What you should know

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.

Procedure

Using a text editor, open your custom SmartCardsSites.xml file.
Locate the <AuthenticationMode> tag at the end of each configuration, and replace "EV1" with "EV2".
```
<AuthenticationMode>
  <EV2 />
</AuthenticationMode>
```
Save your changes and close the file.
Using Config Tool, import the modified SmartCardsSites.xml file with the MIFARE DESFire configuration task.
Export the new MIFARE DESFire configuration to your workstations and Synergis Cloud Link units.
