WebSep 5, 2024 · 1 Answer Sorted by: 1 This is the wrong way to implement AES's S-box - most implementations are either hardcoded (they explicitly write the entire S-box as a 256-byte array), or they iteratively build the entries of the S-box, as in the Wikipedia article you linked: 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 ().
