encryption key is deleted from the Smart Card, meaning that the data on the device is lost. Following the
zeroize process, a new data encryption key is generated in the Smart Card and the KryptoDisk 2 must be
initialized again.
There are various alternatives for zeroizing, and which to use depends on what your objective is. The
alternatives, their uses and their consequences are listed below.
NB: When you zeroize the KryptoDisk 2 or Smart Card, the data on the device is lost. Make sure you back up
your data regularly.
Zeroize the KryptoDisk 2 after loss of Smart Card
This method is used if your Smart Card is lost, stolen or malfunctioning.
When you zeroize without the Smart Card inserted, the encryption module in the KryptoDisk 2 deletes the
communication key stored in the device, thus making it unable to communicate with the Smart Card. The data
stored on the device will be permanently lost.
To zeroize without the Smart Card inserted, power up your device while connected to USB power and enter
the Admin menu. Select the Zeroize option and confirm by entering "Y" (press the 9-key). If you want to cancel,
enter "N" (press the 6-key). The device will confirm and prompt you to restart the device. Disconnect and
reconnect the USB cable to complete the zeroize process.
NB: After this process, the data on the device is lost even if you recover your Smart Card. The recovered card
must also be zeroized and used to perform a fresh initialisation of the KryptoDisk 2.
Zeroize both the Smart Card and the KryptoDisk 2 on USB power
This method is used if you are replacing your Smart Card or transferring ownership of the KryptoDisk 2.
When you zeroize both the Smart Card and the KryptoDisk 2, the encryption module in the KryptoDisk 2
deletes both the communication key stored in the device and the communication key stored on the card. This
reverts the KryptoDisk 2 back to factory settings.
To zeroize both the Smart Card and the KryptoDisk 2, power up your device with the card inserted and enter
the Admin menu. Select the Zeroize option and confirm by entering "Y" (press the 9-key). If you want to cancel,
enter "N" (press the 6-key). The KryptoDisk 2 will confirm and prompt you to restart the device. Disconnect
and reconnect the USB cable, and the device will confirm that the zeroization was successful.
Zeroize the Smart Card on Battery power
This method is used if you are replacing your Smart Card or transferring ownership of the KryptoDisk 2 and
cant access a computer.
When you zeroize both the Smart Card and the KryptoDisk 2, the encryption module in the KryptoDisk 2
deletes both the communication key stored in the device and the communication key stored on the card. This
reverts the KryptoDisk 2 back to factory settings.
To zeroize both the Smart Card and the KryptoDisk 2, power up your device with the card inserted and enter
the Admin menu. Select the Zeroize option and confirm by entering "Y" (press the 9-key). If you want to cancel,
enter "N" (press the 6-key).
NB: While you are running on battery power, the device will only zeroize the Smart Card. Until the KryptoDisk
2 is connected to USB power it will not be zeroized. To zeroized the Kryptodisk 2 you will be prompted to
connect the device to a computer. When connected to USB power with the Smart Card inserted, the
KryptoDisk 2 will start to zerioze and confirm the operation when completed.
