Abstract:
Steganography is one of the most important methods of safe transmission of sensitive information in electronic warfare and audio data hiding due to its higher capacity and complexity than other methods, making it similar to entropy. And the interest of researchers is in the field of information security. The most important part of conducting this research is the decoding of LPC, CELP, and MELP audio encoders, which is considered an important innovation in the field of national information security and electronic warfare because these encoders are among the most powerful audio coding methods used by NATO forces. They are used to transmit Speech. In this article the proposed method, the least significant bit method was used to hide the secret information in the carrier audio. The results of simulation and evaluation according to Table 1 show that this method has a large number of security due to its high resistance compared to other methods, and compared with this code, it shows that the MELP method has a higher security than others.
