Information cryptography using cellular automata and digital image processing

Abstract

Abstract In the recent era, security of the data and information is a very big challenge. The society is also facing a lot of challenges to preserve the security of information. The proposed research explores an asymmetric key encryption and decryption method by processing an image. The keys are extracted from the image by selecting a window from the image. The proposed research includes the concepts of cellular automata to increasing strength of the method. The cellular automata technique suggests proposed keys to encode and decode the information by analyzing image pixels intensity.
