Enhanced Audio Encryption using 2-D Zaslavsky Chaotic Map

Audio communication using internet is increasing day by day at a dramatic level. So, in order to secure the communication and increase the privacy of the audio communication this paper proposes a new method using the chaos theory. The zaslavsky map, one of a chaotic map is used because of its hyper chaotic nature and highest positive Lyapunov exponent. The 2-dimensional zaslavsky map values are generated and passed as a key to the AES algorithm. These numbers allow the encryption method to use a larger number of random keys. This ensures that the key length is effective and that the audio files transferred over the internet are secure. An increase in the key space available for the encryption technique precludes brute force attacks on any cryptography schemes, as well as sniffer attacks on the audio files being sent.
