About the Behavior of the Encryption Icon
Bit scramble encryption type
If the transceiver satisfies the following conditions when the encrypted audio data is received, the “ ” icon blinks:
0
Color Code matches.
0
Group ID matches (upon receipt of an Unaddressed Call/ Group Call).
0
Unit ID matches (upon receipt of an Individual Call).
AES/ DES and DES (Built-in DES) formats
If the transceiver satisfies the following conditions when the encrypted audio data is received, the “
” or “ ” icon will
appear blinking. The “
” icon blinks in the DES (Built-in DES) format.
0
Color Code matches.
0
Key ID matches.
0
Group ID matches (upon receipt of an Unaddressed Call/ Group Call).
0
Unit ID matches (upon receipt of an Individual Call).
Enhanced Encryption format
If the transceiver satisfies the following conditions when the encrypted audio data is received, the “
” icon blinks:
0
Color Code matches.
0
Key ID matches.
0
Group ID matches (upon receipt of an Unaddressed Call/ Group Call).
0
Unit ID matches (upon receipt of an Individual Call).
3.4
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
make use of the Encryption function, it is necessary to configure the Encryption Key for SCM using Key Loader. (Refer
to Key Loader.)
