Multikey Feature
This feature allows the radio to be equipped with
different encryption keys and supports the DES-OFB
algorithm.
There are two types:
The encryption keys can be tied
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 If the radio is used for both
Multikey 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.
