Abstract
This paper presents a complex project that aims towards the development and
design of an encryption system with an evolutive key based on the cellular
automata model. The novelty and the main interest in our project is the
orientation towards the hardware implementation. Most of the research effort
was concentrated on the algorithm for generating the evolutive key. The final
solution is based on cellular automata and gives a special constructive simplicity,
simultaneously with a very high complexity of the evolution of the keys. Special
software has been developed for the analysis of different encryption/decryption
strategies with cellular automata. Between the various strategies and algorithms
studied, the best were selected for hardware implementation. The
implementation of the encryption system was realized on the Spartan 3 XC3S400
platform produced by Xilinx. The result is a fast, cheap, efficient and versatile
cryptographic system implemented on a FPGA Spartan III platform.
Keywords: cryptography, parallel computing, cellular automata,
hardware/software co-design.
1 Introduction
In this age of information, communications and electronic connectivity, security
is a topic of general interest that should never be underestimated. The security of
databases, of data communications, of Internet connections, of scientific research
and of personal e-mail and phone calls are examples for cases in which the
encryption of data/information plays a major role. Therefore, cryptography has
become an important field of theoretical research and applications development,
not only in military communications as it was at its origins.
Keywords
cryptography, parallel computing, cellular automata,
hardware/software co-design.
