Claim One:
1. A method for receiving a digital message transmitted from a transmitter, the message having N digits, each of the N digits having any one of M values, and wherein each of the M values k corresponds with a k th -chaotic signal generator having a chaotic characteristic value associated with a chaotic algorithm to generate a chaotic signal, the chaotic signal having been transmitted within a bit period and comprising a series of numbers generated by: inputting a random number to the chaotic algorithm to generate a first chaotic number; inputting the first chaotic number to the chaotic algorithm to generate a second chaotic number; and repeating said inputting the first chaotic number to the chaotic algorithm to generate a second chaotic number, using the second chaotic number as the first chaotic number until all numbers to be transmitted within the bit period are generated, the method for receiving a digital message comprising: receiving the chaotic signal at a receiver storing the chaotic characteristic values of all chaotic signal generators used to transmit the message; and demodulating the chaotic signal to generate the transmitted value k, said demodulating the chaotic signal including: the chaotic characteristic value of the received chaotic signal based at least in part on the chaotic algorithm; matching the determined chaotic characteristic value of the received chaotic signal with the chaotic characteristic values stored in the receiver; and assigning the transmitted value k by reference to the closest match between the determined chaotic characteristic value and the stored chaotic characteristics values.
