Design and Implementation of Area Efficient Cellular Automata for Efficient Cryptography

A novel cryptographic algorithm mainly depends on the cellular automata .In order to get the randomness using cellular automata concept. In this algorithm we have mainly concentrated on cellular automata module we have 8 different rules for different rounds .In previous algorithm the message and key size was 128bit, but in this project to eliminate all the unnecessary logic operations present in conventional Cellular automata. A modified cellular automata is proposed to achieve less area optimization. The design entry is done in VHDL (VHSIC (Very High Speed Integrated Circuit)) Hardware Description Language (HDL) and simulated using ISIM Simulator. It is synthesized and implemented using Xilinx ISE 13.2tool.
