VLSI Design of Secured Cryptosystem
In this paper, the authors proposes Image cryptosystem scheme to achieve High speed and to improve the security level by using Discrete Wavelet Transform (DWT) and Chaos based approach in to the image. Internet now a day is one of the most popular modes of communications, and it suffers from a vital issue of not supporting the security of the confidential data during transmission. In this work, a high-speed cryptosystem for image data has been developed for efficient and secured communication over Internet. In order to build high quality image of JPEG 2000 codec, an effective 2-D FDWT algorithm has been performed on input image file to get the decomposed image coefficients.
