A Fast Encryption Algorithm for MPEG Audio
Jiaoying Shi · Acta Simulata Systematica Sinica · 2001
With the flourish of Internet and World-Wide-Web, multimedia information security become more and more important for multimedia commerce. Several contributions in the literature emerged in recent years. However, they focused on Video data streams, say, MPEG video. In this paper, we present a novel encryption algorithm for MPEG audio data including all three layers that is based on a random permutation scheme. Because our encryption algorithm is incorporated into the normal coding/encoding procedures, it is very fast, though achieved enough security. We also suggest some directions worth further research works.
