A method of performing mathematical operations in an electronic device, a method of generating pseudo-random numbers in an electronic device, and a method of encrypting and decrypting electronic data

Abstract From the Canadian patent

A method of performing numerical computations in a mathematical system comprises expressing the mathematical system in discrete terms using fixed-, point variables in the computations and extracting a sub-set of digits of a number. The sub-set of digits may represent a random or pseudo-random number. The mathematical system may be a system of non-linear differential equations such as a chaotic system, for example a system with a positive Lyapunov exponent, or a discrete mapping, such as a logistic map an Anosov or a Hénon , map. The method is applicable to encryption and decryption algorithms including stream ciphers and block ciphers systems for generating a digital , signature Hash …
