Abstract: A pseudo-random cipher stream is used to band-spread an optical carrier signal with coded data. A legitimate receiver uses an agreed-upon key to modulate its local oscillator and a resulting beat signal uncovers the band-spread signal. An eavesdropper who does not have the key finds the spread signal with too low signal-to-noise ratio to perform any useful determination of the message sequence. Theoretical bounds based on Shannon's Theory of Secrecy are used to show strength of the encoding scheme and predict it to be superior to the prior art.
