Abstract

Over the last couple of years several encryption algorithms applied to MPEG video streams emerged. Most of the algorithms tried to optimize the encryption process with respect to encryption speed. In this paper we will describe, evaluate and compare four MPEG encryption algorithms. Video Encryption Algorithm (VEA), Modified video encryption algorithm (MVEA), Real time Video Encryption Algorithm (RVEA), Perceptual Video Encryption Algorithm (PVEA) with respect to their encryption speed, security level and string size. PVEA is a generalized version of VEA for Perceptual Encryption, by selectively encrypting FLC data element in the video stream. Encrypting FLC data element makes PVEA maintain the strict-size preservation feature.
