Cryptographic Algorithm Based on Hybrid One-Dimensional Cellular Automata

The theory and application of cellular automata (CA) for a stream cipher-based encryption principle are presented in this study. Certain fundamental transformations developed based on CA regarding decentralized computation modeling different system’s behavior. changes governing state transitions rely simple evolution rules, which can easily be translated into functions using logic operators. A class linear hybrid (LHCA) rules 90 150 is used to implement these functions. Symmetric key systems the foundation suggested algorithm. algorithm use proprieties provided by LHCA order convert plain text cipher vice versa, each case starting from same initial system performing number steps operation. Cellular automata’s parallel information processing property, addition their regular dynamical structure, makes hardware implementation such schemes best suited VLSI implementation. Testing proposed was performed developing both software solutions. Hardware cryptosystem VHDL description language FPGA device (XILINX Spartan3E XC3S500E). Design simulations have been carried out C# programming language.
