• DES-OFB - A form of DES encryption for digital channels that uses output feedback.
This protocol does not result in the degraded range that occurs with analog channels.
11.1.2 AES (Advanced Encryption Standard)
An encryption standard called AES is replacing DES-OFB encryption on digital (P25)
channels. It uses a 128-, 192-, or 256-bit encryption key instead of the 64-bit key used with
DES. EFJohnson radios currently support only 256-bit AES keys. The type of encryption
(DES or AES) is determined by the type of encryption key that is loaded (see
Section 11.2), and not by the PC Configure programming software. AES encryption, like
DES encryption, is an optional radio feature that must be purchased and then enabled at
the factory.
11.1.3 Encryption Available With Various Channel Types
Analog Channels - On analog conventional and SMARTNET/SmartZone channels, DES
encryption is used to provide secure communication. Refer to the next section for more
information.
Digital Channels - On digital Project 25 and SMARTNET/Smart Zone channels, the
DES-OFB or AES protocol is used (AES is available with ARM code 1.20.0 or later and
all 2.0/3.0). Refer to
Section 11.1.4 for more information.
11.1.4 5300 ES Encryption Capabilities
As described in Section Section 9, there are now three different 5300 ES versions which
provide various encryption capabilities.
