Security is as strong as the weakest link. Data
transmission in public communication system is not secure
because of interception and improper manipulation by
eavesdropper. This paper presents the technique for the above
requirement. In the proposed method, we use Steganography
technique where secret message is embedded within a carrier
audio file and the existence of message is hidden from the
intruder. To prevent disclosure of contents of the covered file
cryptography RSA algorithm is used with Steganography to
enhance the robustness of the system. In practice RSA public and
private exponents are chosen to be very large this makes
decryption slow. One way to speed things up is by using Chinese
Remainder Theorem which focuses on modulus calculation. This
paper proposes a faster RSA-CRT algorithm for decryption of
data. Differing from other approaches which try to detect
embedded data or perform time consuming computations as part
of their process we focus on a comprehensive Steganographic
prevention which works in real time on any audio data. In order
to testify our system we propose different attacks on the stegno
embedded file which justifies the robustness of our system.

Audio Steganography
Protecting data from unauthorized access is major concern
in the today’s fast communication world. One of the most
effective techniques has been discussed in this paper
which shows the combination of the most effective
algorithm RSA and LSB results in the most secured and
robust systems. Hiding data in the audio cover file has an
greater advantage. Overcoming the decryption slow speed
by using faster RSA-CRT techniques and testifying the
entire system with the help of two attacks i.e. Brute force
and statistical attack.
