Many researchers had published their papers related with privacy and security of multimedia data which combine the property of compression and encryption. In compression many sensitive parameters are available, without these decoding have no meaning. Encrypting only sensitive parameters make encryption faster and reduce complexity overhead of encryption. Such sensitive parameters in video codec are non-zeros in CAVLC and motion vectors, which are used commonly in many papers. Proposed encryption method is shown with the use of standard 128-bit AES algorithm in counter mode and compare with other selective encryption methods.
