Two Layer Data Security Using 2-D Cellular Automata

Information or message security is very reducing nowadays where the web is known as an exceptionally quick and most advantageous route for information transmission. So it is critical to have an elevated level of security for concealing the secret data. Encryption is a general and compelling technique for concealing recovered data from illicit access. This strategy utilizes a secret key to cover up hidden data in a picture. Be that as it may, it gives just one degree of security over the transmission channel. The point of this proposal is to give 2 degrees of security. The first level includes concealing content behind some pictures utilizing secret phrases and the subsequent level includes encryption utilizing 2D Cellular Automata rules. Encryption is finished utilizing 2-D rules of Cellular Automata. In the primary degree of security, the secret data is inserted in the picture utilizing the Least Significant Bit (LSB) and Enhanced Least Significant Bit (ELSB) procedures with the assistance of a secret phrase. In the dim picture, the LSB method to shroud the data in the picture was utilized. While in RGB picture both LSB and ELSB strategies were used to shroud the data. LSB strategy for RGB pictures uses each of the 3 planes of the picture while the ELSB system uses just one plane of RGB picture. In the second degree of security, 2D cell automata rules were applied on the picture in which hidden data was at that point installed utilizing LSB or ELSB methods. 2D Cellular Automata rules 2, 8, 32, and 128 were utilized to give an additional degree of security to hidden data. Progressively Cellular Automata rules gives increasingly mind-boggling and make sure about encryption procedure. In this way, various principles were used to procure a lot of security. The unscrambling method was completed incomparable style yet in turn around the request.
