![]() ![]() ![]() DES uses a 56-bit encryption key and AES uses a 256-bit encryption key. Enabling P25 encryption is easy.Ī channel or group is programmed to use encryption and a key is loaded into each radio that uses that group. One of the key benefits of P25 Digital Radio over analog radio is the ability to securely encrypt calls without impacting the coverage area. Although analog encryption is possible, this typically degrades the audio quality and also results in a reduced coverage area, as stronger RF signals are needed to clearly receive the encrypted calls. Radios in their group can then talk amongst each other privately, and no outsiders can intercept the communications. ![]() The key is like a secret number or password that must be known in order to decrypt the call. For example, software radio approaches can receive many channels at once, handle both voice and data (including the trunking control channel), decrypt encrypted traffic.Įncryption in radio communications enables secure communication between parties and is achieved by loading the same key into all radios in a group. Hardware scanners such as the Uniden BCD996T offer APCO P25 functionality but software-defined radio (SDR) offers significantly improved flexibility. ![]()
