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.
