摘要：
Chaotic systems are extreme initial parameters sensitive and this feature can be very helpful in the field of cryptography. This paper proposes encryption scheme of audio signal in wavelet domain when logistic maps of deterministic chaos are used for generation of encryption key. Modification of wavelet coefficients may lead to massive degradation of audio signal and this alteration will result to inaudibility.
