White-Box Cryptography and SPN ciphers. LRC method.

Dmitry Schelkunov

Abstract: The method of concealing a linear relationship between elements of a finite field (LRC method) is described. An LRC method based approach to the secure white-box implementations creating problem is considered. SPN cipher characteristics to create its secure White-Box implementation are revealed.
