Performance Analysis of DES Algorithm and RSA Algorithm with Audio Steganography

Abstract

Abstract. In today's era data security is an important concern. It is most demanding issue now days. 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 intruder will not able to retrieve it; however steganography covers that data in some cover file so that 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 audio steganography' and 'DES cryptography with audio steganography'. The coding has been done in MATLAB and stimulated results have been shown.

Audio Encryption Algorithm Based on Chen Memristor Chaotic System

“…With the rapid development of the internet, wireless voice communication technology was widely applied in real-life, and in the process of data transmission there is the risk of information leakage; therefore, audio information encryption research is of great significance. Many traditional encryption algorithms are widely used in audio encryption and achieved good encryption results, such as Advanced Encryption Standard (AES) [1,2], Data Encryption Standard (DES) [3,4] and S-box algorithm [5,6], etc., Although these algorithms have perfect encryption technology, some algorithms still have some defects and cannot fully ensure the security of encryption. The main disadvantage of AES is that it uses a static S-box in the whole algorithm, which damages the security of AES and may be subject to different algebraic attacks.…”
