The information security becoming more important and attract much attention nowadays as the number of data being exchanged over the internet increased.
There are various techniques to secure the data communication, but the well-known and widely used techniques are cryptography and steganography.
Cryptography changes the form of data in another form that is unreadable by anyone except the intended receiver.
Steganography hide the existence of the secret data in other cover media so no one can detect there is a hidden data except the intended receiver.
In this research, we proposed a new technique for securing the data communication systems by combining cryptograph and steganography techniques.
The cryptography algorithm that was used in this research is MJEA algorithm; it is a symmetric (64-bit) block encryption algorithm with (120-bit) key.
For steganography we designed an enhanced form of LSB algorithm with Stego-Key with (128-bit) size and 24-bit map color image.
The proposed algorithm has been tested by running some experiment using MatLab under different simulation metrics.
This metrics are impressibility, embedding capacity and security.
The PSNR (Peak Signal to Noise Ratio) and MSE (Mean Square Error) are used in impressibility test and the result showed a good value of PSNR which mean that it is a strong technique.
For embedding capacity we calculated the maximum size of the secret text that can be embedded in the cover image and we tested the effect of increasing the secret data on the PSNR, the result showed a good value of embedding capacity and the increasing on the secret data size doesn't affect the PSNR value strongly.
The security test done by using the histogram and the result showed that there is no difference between the histogram of the cover image and the stego image which indicate to strong security of the proposed technique.
Furthermore, our technique was evaluated by comparing it with other well-known algorithms.
The comparison shows that our algorithm is better than the others in term of PSNR, it has higher PSNR comparing to the others.
All result proved the strength of the proposed algorithm in securing the data communication system.
The proposed technique is proved to provide a secure transition of data over unsecure channel to protect it against any attack.
