WebDec 12, 2024 · Lightweight cryptographic solutions are required to guarantee the security of Internet of Things (IoT) pervasiveness. Cryptographic primitives mandate a non-linear operation. The design of a lightweight, secure, non-linear 4 × 4 substitution box (S-box) suited to Internet of Things (IoT) applications is proposed in this work.

WebSymmetric Cryptography 5 Substitution Boxes •Permutations can also be done over binary alphabets, e.g. n-bit strings. •Permutation on n-bit strings can be described by n/2 x n/2 “substitution box”, or “S-box”: 3/10/2012 Cryptography 9 One-Time Pads •There is one type of substitution cipher that is absolutely unbreakable. 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. To do so, add the following line at the top of your script: from crypto.sage.sbox import SBox
