Using the Multikey Feature

This feature allows the radio to be equipped with different
encryption keys and supports the DES-OFB algorithm.
There are two types:
•
Conventional Multikey
(strapped), on a one-per-channel basis, through Customer
Programming Software. In addition, you can have operator-
selectable keys, operator-selectable keysets, and operator-
selectable key erasure. If talkgroups are enabled in
conventional, then the encryption keys are strapped to the
talkgroups.
•
Trunked Multikey –
conventional and trunked applications, you have to strap your
encryption keys for trunking on a per-talkgroup or
announcement-group basis. In addition, you may strap a
different key to other features, such as dynamic regrouping,
failsoft, or emergency talkgroup. You can have operator-
selectable key erasure.
