Abstract:   (593 Views)
Different applications same personal, business, military, healthcare and many others need secure audio transferring of signals. Attackers are in ambush and access to these voices will be dangerous for owners. Cryptography caused to high changes and noise on audio. Steganography is a good method for set crypto audio in cover voice to attacker can’t doubt to it. In our proposed method Diffie–Hellman exchange key and one-time pad algorithms used for secure session and wavelet transformation and exclusive-or help us for steganography of encrypted audio in cover audio. We implement and analysis our algorithm by different frequencies and bit rates then compare it with other steganography methods. High transparency in cover audio, fast cryptography in steganography and speed up transferring with vast hidden bit counts convert our proposed method to the novel and optimized idea for secure voice signals.
