Abstract: This research introduces chaos-based speech steganography and quantum cryptography methods that are respectively based on (LSB) or Least Significant Bit and (QOTP) or Quantum Onetime Pad. In the schemes suggested, for scrambling and selection, two chaotic maps have been used, standard map and Lorenz map. The standard chaotic map is used as key two times, one time for scrambling a text message and second time for selecting the position where the text message will be hidden. As for the Lorenz map, it is used as key to select the frames in which the text message is hidden. Then, the data are embedded based on the indices for the ordered sequence of the host speech LSB’s samples. Finally, encrypting the embedded data by using one of the quantum cryptography mechanisms which is quantum one-time pad. For the scheme proposed an analysis is discussed. It deals with the key generation drawbacks and distributions for quantum one-time pad through the use of the chaotic map and the quantum laws concepts. The proposed method satisfies the main requirements of steganography, robustness, hidden data capacity and perceptual transparency. Results of the experiments, signal-to-noise ratio, waveform analysis and others, showed that the stego-speech has high qualities. The analyses showed the effectiveness of the method suggested and as a result it can be used for securing communication.
