Analysis of pixels permutations based on discretized Chirikov map

In this article, a study permutations of pixels based on discretized two-dimensional Chirikov map in images with dimensions N × N. Specific properties of map that can be used by an attacker to recover the original image. For images with dimensions N × N the vulnerability of permutations to brute force attacks, and the ability of intruder to restore the original image without setting the value of keys permutations is...
