Abstract :
We propose an encryption scheme for MPEG video, which uses a permuted Huffman table to encode the input symbols, and then rotates and XORs (exclusive or) the encoded bit stream. This scheme adds very little computational overhead to the MPEG video compression process, and therefore the implementation is fast enough to meet the real-time requirement of MPEG video applications. In our analysis, it is also robust to both plaintext and ciphertext attacks. In addition, our scheme can be applied to all MPEG compression standards.
