Encryption
is the function used to enhance the confidentiality of communications by encrypting audio data while
communicating by voice on a P25 digital channel.
The following Encryption function can be used in a P25 system:
0
AES/ DES encryption type
0
DES encryption type (Built-in DES)
A Secure Cryptographic Module (hereinafter referred to as “SCM”) needs to be installed in the transceiver in order to use
the Encryption function by means of AES/ DES. The transceiver encrypts audio data or decrypts the encrypted
communication data using the encryption method (DES or AES) configured on the SCM.
To use the Encryption function by means of DES (Built-in DES), DES 4 Keys needs to be enabled by using KPG-D1/ D1N.

Toggling the Encryption during Transmission between
Enabled and Disabled
While a P25 digital channel for which “Select” is configured in
Encryption
is selected, pressing the
Scrambler/
Encryption
key can toggle Encryption during transmission between enabled and disabled.
Or, Encryption during transmission can be toggled between enabled and disabled by pressing the
Menu
key to enter Menu
Mode, and then selecting “Scrambler/Encryption”. (Refer to Common FUNC
The status of Encryption, either enabled or disabled, configured by means of the
Encryption
key or the
Menu
key is applied
to all P25 digital channels.

Configuring Encryption during transmission to be enabled
1
Press the
Scrambler/Encryption
key while Encryption is disabled.
The “
” icon or “
” icon appears and Encryption is enabled.
Pressing the
PTT
switch encrypts and sends the communication data.
However, when the transceiver actually transmits, the configuration of
Encryption
for each P25 digital channel, the configuration of
Encryption
for the Talkgroup ID List, or the configuration of
Encryption
for the
Individual ID List is prioritized.
Note
The “
” icon appears if the encryption type is AES, and the “
” icon
appears if the encryption type is DES.
