Abstract :
This paper proposes a nonpositional encryption scheme built on the basis of nonpo-
sitional polynomial notations (NPNs). To develop the cryptographic transformation system,
there were implemented a Feistel network, S-boxes and encryption algorithm KazCipher based
on NPNs. The S-boxes were specifically designed for the proposed encryption algorithm. Lin-
ear and differential analyses of S-boxes have been conducted. The results of avalanche effect
tests of the algorithm are provided
Keywords :
