15 COMMUNICATION SECURITY
15.2 Encryption (NXDN Digital)
Key ID: Any value other than 0
The transceiver searches the encryption key data configured for the transceiver. If the Key ID included in the encryption
key data, which was used for encryption of the received communication data, matches the Key ID included in the
encryption key data which is configured for the transceiver, the transceiver can use the encryption key data to decrypt
the data. If the data is properly decrypted, the received audio sounds from the speaker. If the data is decrypted
incorrectly, the received audio sounds incompletely from the speaker. The transceiver mutes the speaker if the Key IDs
do not match.
If Encryption Is Disabled:
Following are the transceiver behaviors that may vary depending on the configuration for Encryption Type
(Type 1 or Type 2):
Type 1
The transceiver behaves in the same manner as with Encryption enabled.
Type 2
The received audio does not sound from the speaker.
Note
Upon receipt of unencrypted communication data, the transceiver emits the received audio from the speaker according to the audio
control conditions regardless of the Encryption status (enabled or disabled) or configuration for Encryption Type.
Configuration using KPG-169D/ KPG-170D/ KPG-175D
Configuring the Encryption Type (
Multi-key List
Multi-key List is the list to configure the encryption key data, that is used for encryption and decryption of communication
data. A maximum of 16 sets of encryption key data can be configured in the Multi-key List by using KPG-169D/ KPG-170D/
KPG-175D.
Key Data
Key Data allows you to configure the encryption key data in the range of 1 to 32767.
Key ID
Key ID allows you to configure an ID code to identify the encryption key data in the range of 0 to 63. 0 can redundantly be
configured for more than one Key ID. The transceiver's behavior upon receipt of the encrypted communication data varies
depending on the configuration for Key ID. (Refer to
Communication Data on page
The encryption key data configured in the Multi-key List can be allocated to each channel by specifying the corresponding
Multi-key List Number.
