In this paper, the encryption efficiency of the chaotic carrier, which is defined as the signal-to-noise ratio (SNR) of the encrypted message after filtering the combined signal of chaos and signal, is considered as the basic measure of the offered security. Hence, the lower the SNR of the filtered signal is, the higher the encryption efficiency of the system that is achieved. For the numerical calculations of this work we have considered a typical semiconductor laser.
