Key Generation
The keyset is a common credential all radios use when optionally encrypting UDP/IP and
TCP/IP data over a SpeedNet network. Keysets are thus used when AES 128-bit encryption
is enabled (SpeedNet Client tools’
Security>Encryption
tab using the
Enable Encryptio
n
check box). Keysets must be installed on all participating radios to be available for use; it
is not suffi cient to merely generate them in the KeyGen tool. The KeyGen tool generates
keysets randomly without user input; the user does not provide seeds or other data. The
Key Generation
window is used to update keysets. For a network or security confi guration
to be applied to the radio, the confi guration fi le must be encrypted and authenticated with
a current keyset. Up to six keysets can be loaded into a radio at a given time. At most one
keyset is active at any given time. Radios can “roll forward” to new keysets upon prompting
by users or when data of a newer keyset is received from another radio. Radios do not
“roll backward” to previous keysets.
Adding a Keyset
To add a new keyset, open the
Key Generation
tab and click the
Add Keyset
button.
See Figure 19.
Figure 19. The Key Generation window.
Each time the
Add Keyset
button is clicked, the next consecutive keyset number will
be automatically added to the Install Keyset list as shown in Figure 20 on page 16.
