I am trying to create linear approximation table of aes sbox to better understand linear cryptanalysis, i have followed the formula in this paper (page 7 of pdf file) to be able to generate the lin. In the paper, we briefly analyze the aes algorithm, substitution s boxes, linear and differential cryptanalysis, and describe a randomly key dependent s box and inverse s box generation algorithm.

An Introduction To Linear Cryptanalysis – Kevin Liu

An Introduction To Linear Cryptanalysis – Kevin Liu We review their methods and then consider how the choice of s box affects the success of a greedy linear cryptanalysis algorithm devised for one round s aes. It is proposed a new technique to randomize the s boxes of the original saes employing chaotic sequences. then, we study the linear criptanalysis of the proposed schemes. We need to form a linear approximation, involving the plain text, key and the state before the last rounds, which has a good bias. the non linear components in the cipher are only the s boxes. so, we use the lat to obtain the good linear approximations. /* this program is used to derive an s box using an irreducible polynomial of degree 8 * and an affine transformation. it can take polynomials of degree 8 that are reducible, * but the results will not be unique. * * the program can be called with p or w to print or write the s box to a file.

Aes has been designed to have very strong resistance against linear and differential cryptanalysis. after the new proposed algorithm successfully passes the nist statistical tests, we will perform algebraic attack in attempt to break the cipher and test the security of this new design. They analyzed the aes algorithm, substitution s boxes, linear and differential cryptanalysis, and described a randomly key dependent s box and inverse s box generation algorithm. Aes revolves around the s box, a nonlinear substitutive table that is essential to attain the level of cryptosecurity. in this paper, there are several methods discussed as how to increase aes s box functionality with regard to new cryptographic threats and their effectiveness.
