WebIn cryptography, an S-box ( substitution-box) is a basic component of symmetric key algorithms which performs substitution. In block ciphers, they are typically used to obscure the relationship between the key and the ciphertext, thus ensuring Shannon's property of confusion. Mathematically, an S-box is a nonlinear [1] vectorial Boolean function. WebNov 4, 2024 · Confusion and diffusion are two important cryptographic properties [ 1 ]. The confusion is responsible for making the relation between key and ciphertext as complex as possible, and the diffusion is to spread the internal dependencies as much as possible. Both concepts are very important for the overall security and efficiency of the ciphers.
