2.3.2 Software Encryption Layer
CAUTION
DATA LOSS. If the software encryption key / passphrase is lost, the RMC module will be rendered
unusable.
NOTE
Refer to paragraph 5.4 Software Layer Encryption for information regarding the actual
commands and procedures used to create and log into the software encryption layer
NOTE
If the drive is going to be partitioned, the partition(s) must be created before the software encryp-
tion is activated.
To create the software encryption layer, the user must first log into the HWE layer. After that
procedure has been accomplished, creation of the Software Encryption (SWE) layer can begin.
Software encryption is performed before the RMC module is formatted or mounted. Multiple RMC
modules can be encrypted using the same or different encryption key / passphrase. In addition, RMC
modules can be partitioned and have each partition use the same or different encryption key /
passphrase. Before attempting to encrypt the RMC module, the status should be checked. If the status
is not correct, creation of the SWE layer will fail. After the software encryption has been performed, the
RMC module can be formatted and mounted.
Subsequent use of the RMC module is dependent upon the proper encryption key / passphrase
being entered using the CL). Failure to enter the proper information will result in the RMC module
being inaccessible for data storage or use.
2.3.3 Zeroize
There are two methods to zeroize the DTS1:
• Local
• Remote
To locally initiate zeroization, the KEY CLEAR button is depressed and held for a minimum of five
seconds. To remotely initiate zeroization, the Zeroize_N signal is shorted to ground for
approximately five seconds.
The Zeroize_N signal (connector J2-1) is internally pulled-up to +3.3V. The external device is
required to sink no more than approximately 3.3 mA when Zeroize_N is shorted to GND. This can
be accomplished by a switch, relay, or an open drain/collector type semiconductor device as long
as the DTS GND reference (connector J2-3) is used. Refer to paragraph B.2 Utility Connector J2
/ Utility Lab Cable for additional information regarding external connections.
