Nonlinear substitution S-boxes based on composite power residue codes
Михаил Иванович Мазурков, Артем Викторович Соколов · Radioelectronics and Communications Systems · 2013
A design technique based on the composite power residue codes has been proposed for building new constructions of nonlinear substitution S -boxes of length N = 256 and volume | S | = 8.6248×10 13 . The synthesized constructions possess good cryptographic properties, appreciably amplify and extend the class of Nyberg constructions of the Rijndael cipher and also ensure the possibility of their application as a long-term key.
