Abstract

Many people consume multimedia content (images, music, movie) on portable devices like DVD player, MP3 player, Portable Multimedia Player and also through Internet. Problem statement: The conventional algorithms such as DES and AES cannot be used directly in multimedia data, since multimedia data are repeatedly have high redundancy, large-volumes and require real-time operations, such as displaying, cutting, copying, bit-rate conversion and so forth. A block cipher is usually used to encrypt multimedia content because of its reasonable security and performance. Approach: In this study, we introduce a naive approach of efficient multimedia content encryption scheme which uses a block of bits rather than bytes or pixels. The proposed block cipher encrypts any type of compressed multimedia content by random substitution using binary tree traversal, row shifting and column shifting. Results: Experimental results show that the new algorithm has better performance than DES algorithm, encrypting multimedia content by dividing the plaintext by blocks. Conclusion: The proposed algorithm is implemented for all types of multimedia files like audio, video, images and text data and this algorithm can be used to multimedia data during transmisson through Internet or through any communication channels.
