Operating Mode
TRANSEC Module HTTPS Interface
Accepts a 10- to 32-character Passphrase that is combined with the previously entered
Seed Key to generate TEKs.
Once the Passphrase is entered, click Update Passphrase to finalize this change.
The user can program a second seed key and passphrase to generate a second set of
TEKs. These keys will lie dormant until the user activates them by clicking Activate
Future Key. At that time, the following happens:
1. The active TEKs are replaced by the ones generated with the Future Seed Key
and Future Passphrase.
2. The Current TEK gets reset to 1.
Secondary modems connected to this one will also activate their Future Keys.
3.
NOTE: The [Activate Future Key] button is active only when the following conditions are
met:
1. The modem is in Primary mode (see Encryption Mode, explained below).
The Current TEK is greater than 1.
2.
Enter a 32-character Future Seed Key in this text box to generate a TEK when the
TRANSEC Module is given a Future Passphrase (described below).
Re-enter the newly created Future Seed Key in this text box to ensure its accuracy.
Once the Future Seed Key is entered and confirmed, click Update Seed Key to
finalize this change.
Accepts a 10- to 32-character Passphrase that is combined with the previously entered
Seed Key to generate TEKs.
Once the Passphrase is entered, click Update Passphrase to finalize this change.
Set encryption in the TRANSEC Module as Primary or Secondary.
Note the following:
If Primary is selected, the TRANSEC Module will allow the user to advance the
•
TEK and activate the future key independently of any other modems.
If Secondary is selected, the TRANSEC Module's TEK automatically mirrors the
•
TEK of the primary modem and the module will activate the future key when the
primary modem activates its future key.
Click Update Mode when done.
