METHODS AND APPARATUS FOR ENHANCED CMEA INCLUDING A CMEA ITERATION PRECEDED AND FOLLOWED BY TRANSFORMATIONS AND EMPLOYING AN INVOLUNTARY LOOKUP

摘要

Method and apparatus,For the CMEA of enhancing, ECMEA, processing. Forward direction ECMEA and reversed ECMEA processes provide. The text of futures ECMEA processing decryption encryptions is handled by reversed ECMEA processes and the text of reversed ECMEA processing decryption encryptions by forward direction ECMEA. Futures ECMEA processes are with the first transformation, CMEA process iteration, the second transformation. Reversed ECMEA processes use a first time inverse conversion, CMEA process iteration, the second inverse transformation. In transformation and inverse transformation, with CMEA iterative process, using secrecy biasing to improve safety. The iteration of the transformation and above-mentioned CMEA processes also applied one involuntary look-up table of tbox functions of enhancing.
