WebAug 27, 2024 · In this paper, we design a new white-box block cipher based on addition/rotation/XOR (ARX) primitives and random maximal distance separable (MDS) matrix, white-box ARX (WARX), aiming for efficient implementations in both black- and white-box models. Each letter is represented by a number modulo 26. Though this is not an essential feature of the cipher, this simple scheme is often used: To encrypt a message, each block of n letters (considered as an n-component vector) is multiplied by an invertible n × n matrix, against modulus 26. To decrypt the message, each block is multiplied by the inverse of the matrix used for encryption.

Calculate A * B mod C for B values 0 through C-1. step 2. The modular inverse of A mod C is the B value that makes A * B mod C = 1. Note that the term B mod C can only have an integer value 0 through C-1, so testing larger values for B is redundant.
