17 COMMUNICATION SECURITY
17.3 Encryption (NXDN Digital)
Writing the Configuration Data to a Transceiver with Zeroize Enabled
All encryption key data configured on an SCM are deleted when writing the configuration data to the transceiver with
Zeroize enabled by clicking on the Zeroize checkbox in the Write Data to the Transceiver dialog box in KPG-111D/ DN.
Entering Incorrect Transceiver Passwords 15 Times in a Row
All encryption key data configured on an SCM are deleted if an incorrect password is entered 15 times in a row when
turning the transceiver ON with the transceiver password configured. In this case, the user will not be notified that the
encryption key data has been deleted. Therefore QQKEY ERASED" does not appear on the main display.
Also, the number of failed times cannot be reset until the entered password matches the password configured in the
transceiver even if the transceiver is turned OFF.
Configuration using KPG-111D/ DN
Deleting all encryption key data configured on the SCM (
Multi-key List
Multi-key List is the list to configure the encryption key data and the encryption key information, that are used for
encryption and decryption of communication data. A maximum of 16 sets of encryption key data and encryption key
information can be configured in the Multi-key List using KPG-111D/ DN.
The parameters that need to be configured vary depending on the encryption type to be used.
Bit scramble encryption type
To use bit scramble encryption, the encryption key data needs to be configured in the Multi-key List.
 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
 Key Name
Key Name allows you to configure using a maximum of 14 alphanumeric characters and symbols a name
corresponding to the encryption key data.
AES/ DES encryption type
An SCM is required for Encryption by means of AES/ DES. To use an SCM, encryption key data must be configured on the
SCM by using a Key Loader. (Refer to
A CKR ID, which is the encryption key information used to associate with the encryption key data configured on an SCM,
needs to be configured in the Multi-key List.
 CKR ID
CKR ID allows you to configure a CKR ID of the encryption key data configured on an SCM in the range of 1 to 4095.
