Type of Communications and their respective features
Encryption Method
Using the Master key and algorithm, the encryption table for the data
encode is created. Therefore, the Master key and algorithm must be set to
the same values for both the transmit and the receive units.
The actual encryption code is selected from the encryption table by the Air
Key.
In the Fixed Encription mode (Flag: 00), the transmit data does not contain
the Air Key. At the receive end, therefore, the same Air Key must be
obtained in advance to select the encrption code and decode the signals.
In the Random Encrption Mode 1, 2 (Flag: 40), the Air Key selected at the
transmit end is sent along with transmit data. At the receive end, the
received data will be decoded by selecting the encryption table using the
received Air Key.
In the Random Encrption Mode 3, 4 ( Flag: 50), the random number coded
Air Key is sent along with transmit data. At the receive end, the received
data will be decoded by selecting the encryption table using the received
Air Key.
In the Random Encrption Mode 2, 4 (algorithm 80 – 99), the encryption
code will be changed in every 20 mSec. At the receive end, the received
data will be decoded by changing the encryption code in every 20 mSec.
