17 COMMUNICATION SECURITY
17.3 Encryption (NXDN Digital)
Secure Cryptographic Module (SCM) (for AES/ DES Only)
The Encryption function by means of AES/ DES 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. The encryption and
decryption of communication data using AES/ DES encryption is not available in a transceiver where no SCM is installed.
To use the Encryption function, the encryption key data must be configured on the SCM by the use of a Key Loader. (Refer
to Key Loader on this page.)
Note
This function is unavailable for NX-200S/ NX-300S.
Configuration using KPG-111D/ DN

Applicable SCMs
Note
• The Encryption function using AES/ DES is unavailable if an SCM having firmware version earlier than the versions described above is
installed in the transceiver.
• Information (such as the model name and the firmware version of the SCM installed in the transceiver) can be viewed in the
Transceiver Information dialog box in KPG-111D/ DN.
Installing KWD-AE20/ KWD-AE21/ KWD-DE21
Refer to the Installation Manual supplied with KWD-AE20/ KWD-AE21/ KWD-DE21 for instructions on how to install
KWD-AE20/ KWD-AE21/ KWD-DE21 in the transceiver. Contact Kenwood to inquire about Installation Manual.
Key Loader
The Key Variable Loader and Software Key Loader enable configuration of the encryption key data on an SCM, or deletion
of the configured encryption key data.
Note
The Software Key Loader (KPG-151AE) cannot be used to configure the encryption key data on KWD-AE20. To use KWD-AE20,
encryption key data must be configured by using a Key Variable Loader.
