Further, you can compute the whole block transform as a giant boolean circuit (aka bitslicing). This has various advantages, sidechannel resistence being one, but surprisingly it outperforms a more traditional implementation in many circumstances (e.g. in pure-python implementations: https://github.com/DavidBuchanan314/python-bitsliced-aes https://github.com/DavidBuchanan314/python-bitsliced-aes )
