Description:
The phenomenon of spectral equivalence of component Boolean functions of Nyberg-design S-boxes has been investigated. An effective algorithm for removing the spectral equivalence is proposed based on the introduction of random modifier into each component Boolean function of S -box. The analysis of S -boxes generated on the basis of the proposed algorithm corroborates its efficiency and shows high cryptographic quality of S -boxes.
