“…Let's consider a way to obtain an S-box consisting of three steps. At the first, an irreducible polynomial is chosen that step generates a multiplicative group in the Galois field GF(2 8 ) and an irreducible polynomial is called a base [14]. The selected polynomial is exponentiated modulo P(x):…”

“…According to [14], the degree of nonlinearity of Boolean functions NL(f) is defined as the minimum Hamming distance between the i-th Boolean function and linear functions. Degree of non-linearity NL(f) is determined using the W.Hadamard transform.…”

“…The robustness of the cipher is directly related to the level of confusion introduced in the ciphertext, emphasizing the importance of this technique in guaranteeing robust data security (Chen et al, 2022) (Mahboob et al, 2022). The cryptographic robustness of the Scryptographic box itself determines the efficacy of a block cipher employing an Sbox (Khompysh, Kapalova, Algazy, Dyusenbayev, & Sakan, 2022). Extensive study has been conducted to generate high-quality S-boxes and evaluate their strength against known criteria such as nonlinearity, bijection, SAC (Khompysh et al, 2022), BIC, linear and differential probability(Y.…”
