21-7.1.3 Key Type
An encryption key is needed when testing in the
encryption mode. There are two encryption key
types that can be selected, either a Test Key or an
External Key. The Test Key is the default and is
used to support most Project 25 testing. The Test
Key is a predefined key that is programmed into
the analyzer for testing purposes only. In order to
prevent compromised security, the Test Key
should never be used for sending secure radio
communications (all Project 25 analyzers use the
same Test Key). The External Key is a key that
has been loaded from a KVL. In order to test
secure communications the keys in both the Unit
Under Test and the analyzer must be the same.
The analyzer provides these softkey selections:
264
TEST KEY
This softkey selects the Test Key saved in the
analyzer's key storage memory.
EXT KEY
This softkey selects the External Key saved in
the analyzer’s storage memory for the selected
algorithm. This key is defined by the customer
and must first be loaded into the analyzer by a
KVL.
erase ext key
This softkey erases from the analyzer’s key
storage memory any External Key saved for
the current algorithm.
load ext key
This softkey starts the sequence of
programming the analyzer with an External
Key for the algorithm selected from a Key
Variable Loader (KVL). This procedure
requires a key loading cable and KVL.
21-7.1.4 Encrypt Self Test
A self test of the encryption functions is
performed at power up. The “Encrypt Self
Test:” field in the SET UP display (Figure 21-
6) indicates the results of the self test, passed or
failed.
21-7.2 Using the Test Key
The analyzer can be used to test radios using
the internal Test Key (707070….hex). To
select the Test Key, place the cursor in the
