VLSI Design and Implementation of Homophonic Security System

Abstract

This work considers a security system, with unconditionally encipher procedure. Such a system enciphering the input data in such way, that they do not finally contain enough information that can be under statistical analysis, in order to break the cipher. The attempt of cryptanalysis is not affected by the available quantity of available cipher text data. This can be achieved with high entropy of the message stream, which is going to be ciphered. The proposed system is based on a polymorphic chipper, latest published, which can be efficiently implemented in hardware. Architecture design, for the efficient VLSI implementation is introduced in this paper. Suggestions for future work and further optimizations are also introduced.
