In recent years, many multimedia and image encryption techniques based on chaotic maps have been proposed. In this paper, the authors propose a novel multimedia data encryption technique called MDEA (Multimedia Data Encryption Algorithm). Proposed encryption scheme is based on two digital chaotic maps, which in turn are used to generate two different chaotic sequences. Detail description of the proposed encryption technique and performance analysis of MDEA on various parameters of security is given in later sections of this paper.
