7-10 Encryption: Advanced Secure Operation
7.7 Advanced Secure Operation
NOTE: The Advanced Secure feature is available only on radios that have been equipped by the
factory to support it. The radio must also be equipped with an encryption module.
Advanced Secure incorporates the Multikey feature and a dual-encryption feature into the existing
secure system. Multikey allows a radio to be equipped with multiple encryption keys. A default key is
included and is associated with the current mode. The keys are strapped to a given mode or are
operator-selectable and can be indexed into groups of keys (for example, 16 keys can be indexed
into two groups of eight keys). The keys are loaded using a manual keyloader.
In addition, your radio can support up to eight different encryption algorithms simultaneously.
7.7.1 Multikey Operation
The multikey feature can be used in both conventional and trunked applications.
• Conventional Multikey - The encryption keys can be selectively strapped, one per each chan-
nel, by a qualified radio technician. In addition, you can have operator-selectable keys, opera-
tor-selectable indices, and operator-selectable key erasure. Encryption keys are loaded into the
radio through a KVL.
• Trunked Multikey - If you use your radio for both conventional and trunked applications, the
encryption keys have to be strapped for trunking on a per talkgroup, or announcement group,
basis. In addition, a different encryption key can be strapped to other features such as private
call, dynamic regrouping, failsoft, interconnect, system wide, or emergency talkgroup.
5. One of the following occurs:
If the radio receives an acknowledgment from the dispatcher,
five tones sound.
If the radio does not receive an acknowledgment from the
dispatcher, the display shows
NO ACK.
After the radio is rekeyed, it displays
REKEYED and returns to
dispatch mode.
If the dispatcher does not allow it to be rekeyed, the radio
displays
DENIED and returns to dispatch mode after three
seconds.
