P25. It protects control channel control messages, and hides group and individual IDs. • An revision to the Key Fill Interface Standard is in progress. The Encryption Task Group completed a draft addendum that has been provided to the TIA TR-8.3 Encryption Subcommittee. TR-8.3 has agreed to use the material in the addendum provided by theAs P25 is a digital protocol, it is technically straight-forward to encrypt voice and data traffic, something that was far more difficult in the analog domain systems it is designed to replace. However, P25 encryption is an optional feature, and even radios equipped for encryp-tion still have the capability to operate in the clear mode.

Current P25 radios do not tie the decryption behavior of their receiver to the encryption behavior of their transmitter. That is, as long as a receiving radio has the correct key loaded, it will decrypt and play all incoming encrypted transmissions it receives on the current channel, even if it is itself set to transmit in clear mode.
