Scrambler (Analog)/ Encryption (P25/ Nxdn); Secure (Encrypted) Transmission - Kenwood NX-5700 Mode D'emploi

SCRAMBLER (ANALOG)/ ENCRYPTION (P25/ NXDN)

Note:
The Scrambler function can be used only in Analog Conventional Operation.
●
In NXDN systems, there are two types of encryption, namely bit scrambling method (built-
●
in encryption function) and AES/ DES (SCM*). In P25 systems, only AES/ DES (SCM*)
encryption is available.
* SCM (Secure Cryptographic Module) is a hardware cryptographic module developed
by JVC KENWOOD to provide cryptographic securities for digital two way radios.
Ask your dealer for details concerning the Encryption DES/ AES settings.

SECURE (ENCRYPTED) TRANSMISSION

Press the key programmed as [Scrambler/ Encryption] to switch the transceiver to
secure (encrypted) transmission.
Alternatively, press the key programmed as [Menu] to enter Scrambler/ Encryption
Mode using the Menu Mode.
The Scrambler indicator (
●
function is turned ON.
Pressing the PTT switch after the Scrambler or Encryption function has been turned ON
●
encrypts the transmitted signal.
Each group member must activate their respective Scrambler/ Encryption functions to
●
descramble/ decrypt the received signals.
SELECTING THE SCRAMBLER CODE
1
Press the key programmed as [Scrambler/ Encryption Code] to enter
Scrambler/ Encryption Code Mode.
Alternatively, press the key programmed as [Menu] to enter Scrambler/ Encryption Code
Mode using the Menu Mode.
2
Press the [J] and [K] keys to increase or decrease the Scrambler code.
Up to 16 Scrambler codes can be used.
●
Each group member must use the same code in order for the transceivers to
●
descramble the received signals.
3
Press the [ ] key to set the new Scrambler code.
SELECTING THE ENCRYPTION KEY
1
Press the key programmed as [Scrambler/ Encryption Code] to enter
Scrambler/ Encryption Code Mode.
Alternatively, press the key programmed as [Menu] to enter Scrambler/ Encryption Code
Mode using the Menu Mode.
2
Select the new Encryption key using the [J] and [K] keys.
Up to 32 Encryption keys can be used. One of these keys will be used during
●
transmission.
When a call is received, the transceiver will decrypt the call as long as the received
●
Encryption key is in the Multi Key List.
3
Press the [ ] key to set the new Encryption key.
Note:
To restore to the default Encryption key, select "Preset". However, if you delete the
●
Encryption key, it will not be recovered.
