Synthesis method for s-boxes based on galois field transform matrices

Cryptographic methods today are a crucial tool for constructing information security systems. At the same time, to solve the problem of encrypting large amounts of information, block or stream symmetric ciphers are mainly preferred because of their efficiency and proven cryptographic strength, including against perspective quantum cryptanalysis.

Combinatorial method of minimizing boolean functions

Considered the new procedure of logic algebra – super-sticking of variables, which is carried out in the presence of a truth table in complete binary combinatorial system with a repetition or incomplete of the system considered. The efficiency of the algebraic operation of super-sticking variables greatly simplifies the algorithm for minimizing boolean functions, which allows manual minimization of the functions.
