– Multikey Feature
171
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.
