Jun Liu, Zou LingLing, Changsheng M. Xie, Hao Huang · 2006
The security of multimedia data in digital network is commonly provided by encryption. Nevertheless, most current modern encryption algorithms, which only transform a plaintext message that is the simplest form of multimedia data into unintelligible ciphertext, are not appropriate for higher forms such as images and video with very large file sizes. Selective encryption of MPEG video streams has been proposed to reduce encryption requirements, saving in complexity and facilitating new system functionality. In this paper, a two-way selective encryption algorithm (TWAEA) for MPEG video is proposed to compromise the security and speed in the process of encryption
