THE AVALANCHE EFFECT IN ENCRYPTION ALGORITHMS BASED ON THE DISCRETE CHAOTIC MAPS

Abstract

The avalance effect has been investigated in an encryption algorithm being developed on the basis of the discrete chaotic maps. The avalanche effect has been analyzed in a discrete tent map and in the basic transformation based on the Feistel network with the use of the indicated map as a nonlinear function. In both cases, the analysis has been conducted in pairs “input value - output value” and “control parameter - output value”. It has been stated that under certain conditions the developed encryption algorithm meets the requirements of the avalance
