HIGH-SPEED PCA ENCRYPTION ALGORITHM USING RECONFIGURABLE COMPUTING

In this work, an originally bio-inspired cryptosystem is developed. It is based on the use of cellular automata (CAs) as pseudorandom bit generators and programmable cellular automata (PCA) to construct the block ciphering functions of the proposed enciphering scheme. The cryptosystem is featured by resistance on different types of attacks and high speed due to the cellular automata's parallel information processing property. The proposed architecture could be efficiently implemented in reconfigurable hardware like field programmable gate arrays (FPGAs) and could be applied in high-speed data communication. The project was implemented in two experimental hardware platforms based on Spartan 3 XC3S400fg456-4 and XILINX Spartan 3E XC3S500E.
