Zeroizing Keys In Target Devices - Motorola KEY 3000 User Manual

Zeroizing Keys in
Target Devices
Important! In order to
zerioze keys, the
KVL 3000 and the target
device must be equipped
with compatible algo
rithms, as follows (A",
B", and C" are used to
represent specific algo
rithms, such as DES, DVI
XL, DVP , etc.):
If KVL has Algorithm A",
target device must have
Algorithm A."
If KVL has Algorithm A"
and B", then target de
vice must have Algorithm
A" and B.'
If KVL has Algorithm A"
and B" and the target
device has only Algo
rithm A", then you must
configure the KVL for Al
gorithm A" as the default
algorithm.
If KVL has Algorithm B"
and C" and target de
vice has Algorithms A"
and B", then you must
configure the KVL for Al
gorithm B" as the default
algorithm.
ASN Operation
Chapter 4 Entering and Loading Keys
Introduction
The zeroize feature allows you to erase an
encryption key (traffic or shadow) stored in a
specific key slot in a secure target device (e.g.,
radio). Zeroizing permanently
encryption key currently stored in the slot. The slot
is then considered to be undefined" and may be
used to hold another encryption key (using the
Loading Keys procedure on page 4-5).
Zeroizing Traffic Keys in Target Devices
1. Connect the KVL 3000 to the target device
using the appropriate cable. Turn both
units on.
2. Use the key to select TRAF from the
Main Menu. The following screen will
appear:
TRAF>0
ALGO DES
LID xxxx
EDIT
3. Press and hold the Del/Shift key, then
press the 0 key to enter zeroize mode.
The following screen will appear:
