Since the description of the algorithm in the analytical form allows for 16 cycles of execution of the shift register with linear feedback, each of which will be carried out 16 operations of multiplication and 15 operations of addition, reduced to 16 multiplying and 15 the operations of addition. The result is an algebraic form of a linear transformation (from a shift register with linear feedback to the multiplication of the matrix in a finite field). In the future, the algebraic type of transformation can be used to effectively carry out differential cryptanalysis.

Due to them, there is no need to store 16 matrices of sizes 256 × 256 each, but need only to perform the multiplication operation, as well as to store the minimum number of matrices of differential analysis. The study allows us to represent the transformation of the data encryption algorithm in an analytical form, in which it is possible to create software to identify the most probable differentials.}, doi = {10.26562/IJIRIS.2019.MRIS10080}, interhash = {b4c66b40ba73821b0373afd7709b673e}, intrahash = {408deb44387678d73086bea2cf2ad45d}, issn = {2349-7017}, journal = {IJIRIS:: International Journal of Innovative Research in Information Security}, keywords = {algorithm block data encryption representation}, language = {English, French}, month = {March 2019}, note = {[1] Federal Agency on Technical Regulation and Metrology: Block ciphers (2015). http://www.tc26.ru/en/standard/draft/ENG_GOST_R_bsh.pdf.
