Storing cryptographic keys on MIFARE Secure Access Module (SAM) cards instead of the Synergis™ key store increases security because the keys cannot be retrieved. The SAM cards must be unlocked to interact with Synergis™ Softwire for cryptographic operations.
Before you begin
- Configure a Synergis™ Cloud Link equipped with an optional expansion module. For more information, see the SY-CLOUDLINK-312 Quick Start Guide.
- Configure SAM cards using a SAM production tool, and install up to three cards.
NOTE: If you install more than one SAM card, the cards must have the same keys. Having multiple SAM cards installed will allow for faster card reads and access decisions on units with heavy access control activity.
