Module
Digital KEYS Encryption is achieved by digitizing the voice signal and encrypting it with random key stream data which means that the voice is first converted into noughts and ones and then further scrambled. Then this jumbled up data is transmitted along with its KEY to the receiving radio which providing it has the correct key to match is able to reverse the process and intelligent voice signal is heard. The Key is a number selected at random at the start of every transmission. For the eaves dropper, all that is heard is a continuous white noise which sounds as if the squelch is open
