Enabling MIFARE DESFire for transparent OSDP readers
2024-10-09Last updated
OSDP readers in transparent mode require you to store the keys on your Synergis™ Cloud
Link unit, or on secure access module (SAM) cards if you have the Synergis Cloud Link 312
model.
Before you begin
Configure the MIFARE DESFire keys on your Synergis Cloud Link unit.
What you should know
Card or PIN mode isn’t supported with OSDP readers configured in DESFire mode
(transparent mode).
Procedure
Log on to the Synergis Cloud Link unit.
Click Configuration
> Hardware, and then select an enrolled OSDP reader.
Click Edit () for the selected
reader's interface.
From the Reader type list, select Transparent
reader (MIFARE DESFire).
From the MIFARE DESFire key location list, select one of the
following:
Synergis key store
The key for decrypting credentials is stored on the Synergis unit. This
option doesn’t require a SAM card.
SAM (Software crypto)
This is the faster of the SAM options, but requires the
SessionDumpKey option to be enabled during the SAM
configuration process. For more information, see the documentation that came
with your SAM card configuration software.
SAM (Hardware crypto)
This option doesn’t require SessionDumpKey to be
enabled during the SAM configuration process.
Note: The SAM options are only available if you have the Synergis Cloud Link 312
model.
Click Save.
If you selected the Synergis key store option, use the
Synergis™ Appliance Portal to access the Synergis key store and
enter the keys:
Select an index.
Click Create new version, and enter a 32-character
hexadecimal key in the text field.
Click Add.
The MIFARE DESFire configuration file used for the indexed keys is compatible with
both software-transparent and non-transparent readers.
Limitation: There are two limitations with software-transparent readers:
Transparent readers currently can’t encode cards.
Cards with transparent mode enabled take about 100 ms longer to read.
