Data Security Using 2d Cellular Automata Rules

Abstract

This paper deals with secure transmission of text. Since we are moving towards complete online era so it is important to encrypt sensitive information before transmission. This paper introduces two levels of encrypting text in image. In first level, ELSB & LSB techniques are used to hide plain text in cover image using password. In second level 2D- Cellular Automata rules are applied to generate final encrypted image.
