Abstract

The recent technological revolutions in both networking technology (the Internet) and highly efficient perceptual audio coding algorithms (e.g., MPEG audio) have stimulated attractive new applications as well as a considerable amount of music piracy. In order to enable a controlled distribution of multimedia content, classical data encryption techniques are proposed to provide a -secure envelope- around the multimedia pay load by means of ciphering all or parts of it. This paper presents a novel approach of securing compressed digital audio by integrating both ciphering and source coding methods into a single scheme.
