This is a signature, or fingerprint, of the Transmission Encryption Keys (TEKs)
generated by the Seed Key and Passphrase. The user can compare signatures on
different modems to ensure that each has the same Seed Key and Passphrase.
NOTE: The TEKs are updated only when a Passphrase is submitted.
The user may generate 26 TEKs from the Seed Key and Passphrase (described
below). The active TEK (1 through 26) is displayed here. When it is desired to change
the encryption key being used to encrypt traffic, click Next TEK to select the next key in
the set of 26 TEKs.
Note the following:
The Next TEK button is disabled when the module is in secondary mode, and the
•
current TEK mirrors the TEK the connected primary modem uses.
The TEK only increments and never decrements; the user cannot re-use a
•
previous key. The only way to reset the TEK to 1 is by clicking Activate Future
Key (described below).
Enter a 32-character Seed Key in this text box to generate TEKs when the TRANSEC
Module is given a Passphrase (described below).
Re-enter the newly created Seed Key in this text box to ensure its accuracy.
Once the Seed Key is entered and confirmed, click Update Seed Key to finalize this
change.
