Claims:

1. Secure Arithmetic and Logic Unit (ALU) for Central Processing Unit (CPU) of Microprocessors having better pipeline randomization for improving DES and other cryptographic protocols against external monitoring attacks by reducing the amount (and signal-to-noise ratio) of useful information leaked during processing.
2: Usage of Proportional Integral Derivative Value Generated by parameter optimization using Genetic Algorithm for Randomisation of Instruction Pipeline.
3:Dynamically configurable logic gates for Chaotic computing including a controller configured to provide a first threshold reference signal; an adder configured to sum the first threshold reference signal and at least one input signal to generate a summed signal; a chaotic updater configured to apply a nonlinear function to the summed signal; and a subtractor configured to determine an output signal by taking a difference between a second threshold reference signal and the processed summed signal from the chaotic updater. , Description:In this invention we promote the use of GAs for evolving pipeline randomization with improved side-channel resistance. Our approach shows potential in both creation of S-boxes as well as in the evaluation. However, we are aware of the difficulties that lookup table approach could pose. Nevertheless, we do believe that our results have practical values. In general, one can consider the results as a proof of existence of S-boxes with desired properties. We expect that the results can be optimized further but the main goal was to find S-boxes with high nonlinearity and low transparency order. In this research we used generic GA but the results can be improved by employing custom made GAs, some other evolutionary algorithms like Estimation of Distribution Algorithm, or even to go outside EA area using Swarm Intelligence algorithms and use algorithms like Particle Swarm Optimization. Above all, this paper promotes evolutionary computation as a serious tool for tackling some hard problems in cryptography i.e. evolving S-boxes and their transparency order. In near future, we expect many more attempts in using those mature optimization techniques on cryptographic and other security-related problems.
