Abstract

In this paper, after a brief summary of the principles of private transmission based on chaotic lasers, we present a new scheme, which exploits the chaotic voltage available across the transmitter laser junction to provide stronger masking of the transmitted signal. With respect to the standard scheme, only one more electrical amplifier and a passive summing block are required at the transmitter, while the receiver is unchanged. The new scheme offers an increased BER differential between the authorized recipient and an eavesdropper. Simulations have been performed by the Lang-Kobayashi model.
