4.5
Secure Cryptographic Module (SCM) (AES/ DES)
The Encryption function in the P25 format can be used by installing a Secure Cryptographic Module (SCM) in the transceiver.
All encryption and decryption of communication data can be processed by the SCM. A transceiver in which no SCM is
installed cannot encrypt or decrypt communication data.
Also, Encryption Key data needs to be configured for the SCM using the Key Loader in order to use the Encryption function.
(Refer to
.)
Applicable SCMs
Following are the SCMs that can be used with the transceiver:
Table 4-2 Available SCMs
SCM
Firmware Version
KWD-AE30
A3.0.3
KWD-AE31
A4.0.3
KWD-DE31
D4.0.3
Key Loader
Using the Key Variable Loader or the Software Key Loader, Encryption Key data can be configured on the SCM and
configured Encryption Key data can be deleted.
Key Variable Loader
An Encryption Key can be configured on the SCM by using the Motorola KVL 3000/ KVL 3000 Plus/ KVL 4000.
After connecting KVL 3000/ KVL 3000 Plus/ KVL 4000 to the transceiver using the KPG-93 (Portable) or KPG-115 (Mobile)
cable, when the transceiver is turned ON, “KEYLOAD” appears on the display and the following operations can be executed:
0
Key Load
An Encryption Key data can be configured on the SCM.
0
Key Delete
The Encryption Key configured on the SCM can be deleted.
0
Key View
A Key ID configured in the transceiver can be displayed.
Software Key Loader
Encryption Key data can be configured on the SCM using the Software Key Loader (KPG-AE1/ KPG-DE1).
When the transceiver is turned ON after connecting the transceiver to a PC with KPG-AE1/ KPG-DE1 installed using the
KPG-36U/ KPG-36X (Portable) or KPG-46U/ KPG-46X (Mobile) programming cable, the following operations can be
executed. “KEYLOAD” appears on the display while KPG-AE1/ KPG-DE1 and the transceiver communicate.
0
Key Load
An Encryption Key data can be configured on the SCM.
