The branch number indicates how much a difference in the input will spread around the rest of the state after the transformation has been applied. The branch number can be used to prove lower bounds on the amount of diffusion that the permutation …

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 vectorial Boolean function.
