Lightweight S-Box Architecture for Secure Internet of Things

WebAbstract— To design a substitution box (S-BOX) using both encryption and decryption. From that, the proposed system can achieve a higher throughput and higher energy efficiency. The S-BOX is designed by using Advanced Encryption Standard (AES). The AES is a symmetric key standard for encryption and decryption of blocks of data. Websage.crypto.sbox uses big endian by default whereas most of Sage uses little endian. So to use the big endian PRESENT Sbox from sage.crypto.sboxes sbox_layer () has to do some endian conversion (i.e. reverse input and ouput of the Sbox). Keep this in mind if you change the Sbox or sbox_layer ().
