A Hybrid Approach of Cryptography

Abstract

This article represents a dual security mechanism based on compressive sensing, quantum chaos map, random pixel exchange, and frequency division approach. It also provides the digital data authentication system based on combined approach of DWT and SVD. Two watermarks are used for dual authentication purposes and compressive sensing is used to provide parallel compression and data encryption. The detail algorithm and approach is explained in the next section. This approach is more effective than other conventional approachs and takes less time and space complexity to the others i.e. AES, DES RSA type data encryption mechanism. This article also provides the parallel compression mechanism which reduced the required memory size. This mechanism also provides the parallel digital data security as well as authentication system which provided more secure communication on the social network and also provides a secure authentication mechanism based on frequency division, compressive sensing, random pixel exchange, etc. The results are shown in the form of images and tables.
