Data Security Using 2d Cellular Automata Rules

Abstract

Abstract-This paper deals with the secure transformation of text. Encryption is the most common method of hiding text from unauthorized access. Two popular ways of sending personal information in a secret way are Cryptography and Steganography. To hide the existence of the message as well as distorts the message itself using this method. LSB and ELSB are the advanced techniques used to hide text in the image. There are two levels to hide the secret information. In the first level of hiding text, data sent to images by using the password and in second level encryption of 2D Cellular Automata used to enhance more security. If one level of security technique is broken by third person then there will be one more level to provide security to that secret information. Encryption will do using 2 dimensional rules of Cellular Automata. The use of Cellular Automata rules is for the parallelism which provides high security during storing and communicating, higher compression ratio and higher encoding of data while comparing with the available security techniques.
