Abstract

The popularity of digital video storage and delivery systems has given rise to the need for video encryption to preserve secrecy and digital rights. Conventional encryption techniques are not appropriate for securing multimedia systems given the need to encrypt a large amount of data in real-time. This paper presents a selective video encryption algorithm that utilizes multiple stream ciphers and a unique multi-key mechanism to improve security while maintaining efficiency and format compliance. Furthermore, the algorithm is well suited for parallel hardware implementation. Finally, experimental results from the encryption of various test video sequences demonstrate the effectiveness of the video encryption scheme.
