Abstract
With the advent of technology large number of images are transmitted and received through the internet. Security and privacy are the two major concerns during digital image transmission. Many encryption techniques have been in the literature. They include several crypto analysis techniques, namely DES, RSA etc. However the research has been mostly stopped in the simulation stage itself. Also the available techniques are time consuming, which pose a serious concern especially during video transmission. Hence it is necessary to develop an indigenous hardware that can be exclusively used for video encryption and decryption. Hardware implementation involves developing the algorithm in VHDL and downloading it in a kit. The proposed work aims at developing video encryption and decryption of binary images. Also the proposed techniques have been extended to gray scale videos with 32 gray levels.
