Steganography of the Keys into an Encrypted Speech Signal using Matlab

This paper highlights the requirement for change in the security and privacy techniques available. In recent times, there have been advancements in the type of attacks possible to Computer systems. In order to meet these challenges, there has been a rise in the need to change the earlier used techniques for encrypting the speech signal. The paper proposes a secure and speedy technique for the cryptography of the speech signal and also performs steganography of the key pairs generate while encryption of the speech signal which is then sent to the receiver. This paper also includes experimental results for the proposed system.
