AES is yet
one of the prominent cryptographic algorithms of the 21st century with the
reputation of excellent performance and reliability. AES revolves around the
S-Box, a nonlinear substitutive table that is essential to attain the level of
cryptosecurity. In this paper, there are several methods discussed as how to
increase AES S-Box functionality with regard to new cryptographic threats and
their effectiveness. We detail the consequences of raising S-Box length and
size, dynamical S-Box producing, higher nonlinearity, and efficient methods of
S-Box calculation by means of hardware and software. Furthermore, it explains
the issues with these improvements and how they impact security measures &
relevant computations. Here it is possible to state that applying all these
modern approaches, it is possible to strengthen the AES S-Box essentially and
ensure compliance with present day demands to cryptographic solutions.
