Encrypting communications
First Claim
1. A method of securely communicating a data chirp signal from a transmitter to a receiver, the chirp signal comprising at least one symbol, each symbol comprising one or more identical chirps, each chirp encoding a symbol value, the method comprising:
- negotiating between the transmitter and the receiver encryption parameters of the chirp signal, the encryption parameters defining at least one property of each symbol of the chirp signal;
at the transmitter, encrypting the chirp signal according to the encryption parameters by generating each symbol of the chirp signal using the at least one property defined by the negotiated encryption parameters;
at the transmitter, encoding data in the chirp signal via the symbol value of each chirp; and
transmitting the encrypted and encoded chirp signal from the transmitter to the receiver.
