Video Encryption using Improved AES with DWT.

摘要

Today data security over the network is a serious concern as the amount of multimedia data is increasing at an exponential rate due to evolution of internet. To secure multimedia data it is encrypted before transmission. Encryption using improved AES with DWT is quite efficient since it provides the real time encryption of digital multimedia contents. In this paper cryptography is used to encrypt the video data and achieves high security. Video encryption has various fields including internet communication, multimedia systems, medical imaging and military communication. A modified algorithm of Advanced Encryption Standard (AES) algorithm with DWT is.
