It is a small-scale version of the DES designed to help beginners understand the basic structure of DES. This class implements the Simplified Data Encryption Standard (S-DES) described in [Sch1996].

WebWhile designing any cryptography algorithm, a substitution box (S-box) is a core and the only component that offers a nonlinear functionality between inputs and outputs. Various researchers propose various S-box designs for different applications. Still, very few of them maintain the trade-offs among cost, performance and security, especially ... WebSage provides a class dedicated to the analysis of S-boxes: crypto.sage.sbox.SBox. Its documentation is available here. To be able to use it, you need to import it.
