Algebraic Cryptanalysis of GOST Encryption Algorithm

  title={Algebraic Cryptanalysis of GOST Encryption Algorithm},
  author={Ludmila K. Babenko and Ekaterina Maro},
This paper observes approaches to algebraic analysis of GOST 28147-89 encryption algorithm (also known as simply GOST), which is the basis of most secure information systems in Russia. The general idea of algebraic analysis is based on the representation of initial encryption algorithm as a system of multivariate quadratic equations, which define relations between a secret key and a cipher text. Extended linearization method is evaluated as a method for solving the nonlinear system of equations… CONTINUE READING
