Introduction
The Motorola Over the Air Rekeying (OTAR)
system is a secure communications system in
which encryption keys can be sent to subscriber
units via radio transmission (instead of directly
connecting a KVL to load keys). This type of
system provides added
convenience in managing and administering
encryption keys.
One of the infrastructure components in an
OTAR system is the Key Management Facility
(KMF). The KMF is a Windows NT based
computer that is responsible for storing and
managing the encryption keys for an OTAR
system, as well as initiating key transmissions to
the subscriber units.
Key Transfer Scenarios
The KVL 3000 can interface with the KMF to
provide the following functions:
D Transfer the encryption keys required
by the OTAR system from the KVL 3000
to the KMF In this scenario, an opera
tor loads the required keys into the
KVL 3000, then connects the KVL 3000 to
the KMF via a standard key loading cable
and transfers the keys (one at a time) to
the KMF for storage and management.
