APPLICABILITY OF TIME AVERAGE STOCHASTIC MOIRE FOR CRYPTOGRAPHIC APPLICATIONS

摘要

An algorithm for the construction of Hash function [1] based on optical time average moire experimental technique is proposed in this paper. Algebraic structures of greyscale colour intensity functions and time average operators are constructed. Properties of time average operators and effects of digital image representation are explored. The fact that the inverse problem of identification of the original greyscale colour intensity function from its time averaged image is an ill-posed problem and is computationally infeasible helps to construct an efficient algorithm for the construction of one-way Hash function applicable in cryptographic algorithms.
