Performance Analysis and Implementation of DES Algorithm and RSA Algorithm with Image and Audio Steganography Techniques

Abstract

In today’s era, data security is an important concern. It is most demanding issue nowadays. It is essential for people using online banking, e-shopping, reservations, etc. The two major techniques that are used for secure communication are Cryptography and Steganography. Cryptographic algorithms scramble the data, so that the intruder will not be able to retrieve it; however, steganography covers that data in some cover file, so that the presence of communication is hidden. There are some techniques that integrate cryptography and steganography to provide multi-layer security. This paper shows the comparison of such two techniques. These are “RSA cryptography with image steganography and with audio steganography” and “DES cryptography with image steganography and with audio steganography”. Stimulated results have been presented using MATLAB software.
