On the division property of s-boxes
Websome properties related to the division property. In this paper we give a complete characterization and reprove many of their results. We show that the division property is actually the dual of the degree of t-products of the inverse S-box and show these two … WebHowever, security is not as enhanced as the designers expected. In fact, division property finds a 13-round distinguisher that improves on the previous distinguisher by 4 rounds. ... Our first discovery is that the lower bounds of the number of differentially active S-boxes provided by the designers are incorrect.

WebThe division property of equality tells us that if we divide both sides of an equation by the same number, the equation remains the same. Suppose you have two pizzas of the same size. You cut each of them into halves and give away one-half from each pizza to your friends. If you measure the remaining portions, you will find that you are left ...
