The substitution (S-boxes) step in the Data Encryption Standard (DES) encryption process plays a crucial role in enhancing the security and confusion properties of the algorithm. The S-boxes are key components of the DES block cipher cryptosystem, and they contribute significantly to the overall strength of the encryption. To understand the role of the substitution
