  • If I understand correctly, there are 4 encryption algorithms available to users of APCO 25 systems: DES-OFB, ADP, 3DES, and AES. Is it possible to determine which one a particular system is using based on the sound or raw data? What I find interesting is that the garbled up encrypted sound still resembles speech.
  • FMP(24) Frequency File, Monthly Update Substantial effort was required to provide this information, and there is an ongoing cost to me to make this data freely available. If this data was useful to you, please donate to support my development of scanner tools and applications.

P25 wasn't originally designed with security in mind. It was designed as a standardized digital replacement for the mess of incompatible digital and analog trunking systems that had grown up in the 80s and 90s. In its basic, as-designed, unencrypted mode, it works well.
Versions of DSD+ that auto-decrypt MotoTRBO basic/enhanced privacy and P25 ADP have been created, but there are no plans to release these. They would only increase the use of real encryption. The team debated whether LRRP (GPS) functionality should be released as some public safety systems use it, but those agencies have the option of encrypting their data, and should be, so LRRP is ok.
  • Dec 12, 2014 · The project that got me really into experimenting with the RTL-SDR dongles is using them to decode P25 digital trunked public service radio systems. I have been a casual scanner listener for years and like to listen to emergency calls nearby.
  • If the user specifies that encrypted traffic should be muted, DSD+ will temporarily lock out encrypted trunked P25 calls and will not tune VC FMPA/FMP24 to the calls. On P25 systems with some encrypted groups, it is no longer necessary to lock out all encrypted groups; just use -e on the command line or press 'E' to lock out all encrypted calls.
  • With this solution in place, the researchers were able to do detailed analysis of the traffic coming from various radio systems and to transmit and receive to P25 radios in their lab. No user commented in " Security researchers crack APCO P25 encryption "

Apr 11, 2013 · The most common digital speech codec is APCO P25, which DSD is able to decode. DSD is also capable of decoding other common digital codecs such as DMR/MOTOTRBO, NXDN, D-STAR and ProVoice. Super cheap software defined radios such as the RTL-SDR can be used to decode these digital voice communication signals instead of expensive radio scanners.
