Design of integrated multimedia compression and encryption systems
Chung-Ping Wu,C.-C.J. Kuo +1 more
TL;DR: This research examines the limitations of selective encryption using cryptanalysis, and proposes another approach that turns entropy coders into encryption ciphers using multiple statistical models that can be applied to most modern compressed audio/video such as MPEG audio, MPEG video, and JPEG/JPEG2000 images.

Security Analysis of Multimedia Encryption Schemes Based on Multiple Huffman Table
TL;DR: A known-plaintext attack is presented to show that the MHTs used for encryption should be carefully selected to avoid the weak keys problem and two empirical criteria for Huffman table selection are suggested, based on which the stream cipher integrated scheme can be simplified.
