Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Considered cryptosystems such as Cardano square lattices are characterized by the high-speed encryption in use today Enhanced Programming computers. This is because the number of different variants rapidly increases with the size of a square. In this paper we have shown that, for the size of 20 × 20, the number of such grids exceeds the number of 1.6 × 260Therefore, these systems have sufficient cryptographic resistance. Application of these systems in conjunction with substitution cipher can still more resist cryptographic attacks.
