Configuring the Radio Network 4 - 9
Packet Encryption (Privacy Menu)
This menu controls the use of encryption on the data packet transmitted
over the air by the radios. The packets are encrypted using the RSA RC4
algorithm using one of up to 4 known keys. Each node in the radio cell
must know all the keys in use, but they may select any one to use for
their transmitted data.

algorithm using one of up to 4 known keys. Each node in the radio cell
must know all the keys in use, but they may select any one to use for
their transmitted data.
The “Key” option is used to program the encryption keys into the radio.
You will be prompted as to which of the four keys you wish to set and
then you are prompted twice to enter the key with echoing disabled.
Depending on whether the radio is authorized to use 40 bit or 128 bit
keys, you must enter either 10 or 26 hexadecimal digits to define the
key.

If the “Encryption” option is set to “off” then no encryption is done and
the data is transmitted in the clear. If the value is set to “on” then all
transmitted data packets will be encrypted and any un-encrypted
received packet will be discards.
