Multikey Feature

This feature allows the radio to be equipped with different
encryption keys and supports the DES-OFB algorithm.
There are two types of encryption keys:
Conventional Multikey
The encryption keys are strapped on a one-per-channel
basis, through CPS. 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
If the radio is used for both conventional and trunked
applications, strap the encryption keys for trunking on a
per-talkgroup or announcement-group basis. In
addition, a different key can be strapped to other
features, such as dynamic regrouping, failsoft, or
emergency talkgroup. You can have operator-selectable
key erasure.
