In this paper a new scheme of digital voice secure communication system is proposed based on chaotic modulation without additional synchronization. The modulation sequence, generated by chaotic logical mapping, is used to encrypt the digital voice signal. In order to hide the characteristics of information signal, the modulation is based on wavelet transform. The method of chaotic masking is also used to randomize the cryptograph. Simulating and analyzing show that the chaotic encrypting system can improve the security and can resist the decipher analysis. Furthermore, the system is easy to actualize.
