MIFARE DESFire readers require cryptographic keys to access a card's secured
credential. When readers are configured to run in transparent mode, these keys are loaded into
the Synergis key store.
Before you begin
The door must have an STid reader with a part number ending in AA or
AD.
Procedure
-
Log on to the Synergis unit.
-
Click , and then select STid.
-
Click Edit (
) on the reader's
interface.
-
In the reader configuration dialog box, from the Key
location list, select Synergis key store.
-
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 STid readers.
Limitation: There are two limitations with software transparent readers:
- Transparent readers currently cannot encode cards.
- Cards with transparent mode enabled take about 100 ms longer to read.
After you finish
The 32 available indexed keys in the
Synergis key store increase security by enabling the entry of keys in components. Clicking
Add between components makes it possible for multiple
stakeholders to each know only part of the required key.
