Web19 de fev. de 2024 · Draw a dots-and-boxes picture of the number 11 f i v e. Use the dots and boxes method to find 424 f i v e ÷ 11 f i v e. Rewrite the division sentence 424 f i v e ÷ 11 f i v e = 34 f i v e in base ten, and check that it’s correct. Use dots-and-boxes to find 2024 f i v e ÷ 12 f i v e. Don’t convert to base 10! Webdifferential propagation property of the large S-boxes and the coefficients can be chosen from the full spectrum of integer. As a result, the number of inequalities for the AES S-box is <4000. Moreover, if the probability of the possible nontrivial differential patterns of the S-box takes two values, 2−6 and 2−7. We also can add

Another very common criteria for an S-box with n input bits and m output bits with m ≤ n (as most commonly used S-boxes are) is that each of the 2 m output values should be reached for exactly (or at least near) 2 n − m input values.
