Robust Audio steganography based on Advanced Encryption standards in temporal domain

In this paper a robust Audio steganography technique is proposed by randomizing and dynamically changing the embedding sequence. Advance Encryption standards is used for providing additional security and robustness to the algorithm and tested for the 30 speech files. The addition of cryptography in steganography increases the robustness and introduces a higher level of security since the key is required to decrypt the secret message. To evaluate the quality of the stego files SNR and Correlation coefficients are calculated and an experimental test is also performed over 10 listeners to identify the change in the original audio and cover audio.
