Hardware Tools for Pseudonondeterministic Block Ciphering

Abstract

Analysis of known approaches of block ciphering designing is presented at this paper. Implementation of the pseudonondeterministic cryptography was proposed to avoid determined drawbacks of known block cipher designing approaches. The automata model was shown to formalize the pseudonondeterministic block ciphering process. The method based on the model was developed. Both method and model allowed to design the structure of specialized processor for pseudonondeterministic ciphering. The structure's blocks were adapted for FPGA implementation.
