Title: Masking messages using chaos

Abstract: We numerically investigate encoding messages on the output of a chaotic transmitter laser and its subsequent decoding by a similar receiver laser and We extract a message masked by a chaotic signal. The chaos was generated by the two ODE describing the chaotic behaviour of four level laser with periodic pump modulation. The mask removal can be accomplished tor digital signals as well as for analogue ones.

Key words: chaotic signal; masking
