Chaos-based video encryption algorithms

Abstract

In recent years, with the development of network technology and multimedia technology, multimedia data, especially video data, are used more and more widely in human society. Some multimedia data applied in entertainment, politics, economics, militaries, industries or education, etc., are necessary to be protected by providing confidentiality, integrity, and ownership or identity. To protect video contents, cryptology, which appears to be an effective way for information security, has been employed in many practical applications[1][2][3]. However, traditional ciphers like DES [4], IDEA [5], RSA[6] and AES[7], are often used for text or binary data, while not suitable for direct video encryption because of the following reasons. © 2011 Springer-Verlag Berlin Heidelberg.
