Smart card usage

Smart cards are credit card-sized cards that contain a CPU and persistent memory. Smart cards

can be used as security devices. You must have Storage Encryption Security user privileges to

activate, register, and configure smart cards.

Smart cards can be used to do the following:

• Control user access to the Management application security administrator roles.

• Control activation of encryption engines.

• Securely store backup copies of master keys.

Smart card readers provide a plug-and-play interface to read and write to a smart card. The

following smart card readers are supported:

• GemPlus GemPC USB

Registering authentication cards from a card reader

When authentication cards are used, one or more authentication cards must be read by a card

reader attached to a Management application PC to enable certain security-sensitive operations.

These include the following:

• Master key generation, backup, and restore operations.

• Replacement of authentication card certificates.

• Enabling and disabling the use of system cards.

• Changing the quorum size for authentication cards.

• Establishing a trusted link with the NetApp LKM key manager.

• Decommissioning LUNs.

To register an authentication card or a set of authentication cards from a card reader, you must

have the cards physically available. Authentication cards can be registered during encryption group

or member configuration when running the configuration wizard, or they can be registered using

the following procedure.
