METHOD FOR CONVERTING LOW-ENTROPY MESSAGES Russian patent published in 2017 - IPC H04L9/00 G09C1/04 H01K1/00 

FIELD: information technology.

SUBSTANCE: method for converting low-entropy messages is that, prior to each alphabet symbol, the corresponding numerical code is randomly assigned, the input message is formed from the corresponding set of alphabet symbols, as numerical code the coordinates of the points on the circle are used, selected in such a way that the distance from any point on the line intersecting the circle, with the exception of the point coinciding with the center of the circle, to the said points on the circle is different, origin point is randomly selected, on the line intersecting the circle, before the start of converting the input message, then using the origin point coordinates and the corresponding numerical code of each character of the input message, the length of segment between them is calculated, which is the result of converting each input message symbol. To determine the coordinates of origin point of each subsequent message, the coordinates of origin point of the previous message are changed using the converting result of previous message.

EFFECT: simplifying the conversion algorithm and increasing the resistance to unauthorized data recovery.
