Securing software defined network transactions using visual cryptography in steganography

In the Software-Defined Network many transactions of data have been made, the need for securing this data very imperative. One of the most successful ways to secure data is by adding layers of both cryptography and steganography. In past years, many attempts to achieve this approach is done, but in this paper, a discussion made on how this approach works on Software-Defined Network, by first hiding secret messages inside the randomly generated image using LSB algorithm and then encrypting it using simple Visual Cryptography which based on creating two noisy images concluded from the original and only can be restored by stacking these images together. At the end of this research, results showed that two layers of security can be more secure than the one layer, this way the attacker can be obscured about the data hidden. The reason behind the implementation of this approach in SDN because of its importance since it’s been used in many organizations and they need the data to be secured. Another problem that occurred in this system, is the latency to transfer the data from one node to another since this approach uses multimedia as a payload to transfer the data, a compression layer must be added, to decrease the amount of data sent through the network. After all this work, the data is now secured by applying two layers of security and faster to transfer hence this data is reduced by compression and simple visual cryptography is used and the BZIP2 compression technique to reduce processing of data.
