4.4
Transceiver Behavior upon Receipt of Encrypted
Communication Data
The transceiver can decrypt the received encrypted data using Encryption Key configured on the SCM.
Following is the transceiver behavior upon receipt of encrypted communication data if Encryption Key data (Key ID and Key
Data) corresponding to the CKR ID in the Multi-Key List is configured on the SCM. (Refer to
.)
0
If the received Key ID matches the Key ID configured on the SCM:
If the received Key Data matches the Key Data configured on the SCM, the transceiver decrypts the received
communication data, and then the transceiver can emit the received audio normally if the received audio data can be
correctly decrypted.
If the received Key Data does not match the Key Data configured on the SCM, the received audio sounds without being
decrypted.
0
In the case that the received Key ID does not match the Key ID configured on the SCM:
No received audio sounds from the speaker.
Note
0
Whether the status of Encryption is enabled or disabled, the transceiver behavior upon receipt of encrypted
communication data is not affected.
0
If the transceiver receives unencrypted communication data, the transceiver emits the received audio from the speaker
regardless of whether the status of the Encryption Key is consistent or inconsistent.
0
While Monitor is enabled, the transceiver emits the received audio from the speaker regardless of whether the status of
the Encryption Key is consistent or inconsistent. However, if the received Key ID does not match the Key ID configured
on the SCM, or if the received Key Data does not match the Key Data configured on the SCM even though the received
Key ID matches the Key ID configured on the SCM, enabling Monitor emits the received audio from the transceiver without
being decrypted.
About the Behavior of the Encryption Icon
The “
” icon appears if the encryption type used for transmission and reception is AES, and the “
” icon appears if the
encryption type used for transmission and reception is DES.
The icon appears in the following manner depending on the status of the transceiver:
0
Waiting
The icon of the encryption type configured on the transmitting channel appears.
0
Receiving
The icon of the encryption type used upon receipt blinks.
In a P25 Conventional system, if the transceiver satisfies the following conditions according to the configuration in
Squelch Type
(NAC or Selective Call) upon receipt of the encrypted communication data, the “
” icon or “
” icon
blinks:
NAC:
0
NAC matches.
0
Key ID matches.
Selective Call:
0
NAC matches.
0
Key ID matches.
0
Talkgroup ID matches (upon receipt of a Group Call).
0
Unit ID matches (upon receipt of an Individual Call).
