The nonlinearity of the S-box (Substitution box) in cryptographic systems, such as AES (Advanced Encryption Standard), is primarily due to the use of the multiplicative inverse in a finite field (typically GF(2^8) for AES). This operation introduces nonlinearity, which is crucial for resisting linear and differential cryptanalysis.
