Abstract

This paper addresses to a variation (modification) of a symmetric block encryption-decryption algorithm based on nonpositional polynomial notations (NPNs). The proposed encryption model includes two stages. The first stage is that a plaintext is split into bit blocks of a given length. Each plaintext block then undergoes an initial transformation, where a pseudorandom sequence (PRS or key sequence) is added bit by bit to the block through XOR operation. The key sequence is generated with a designed PRS generator. In the second stage, an encryption-decryption algorithm based on NPNs is applied to the transformed bit sequence. A computational model has been developed and implemented to test statistical properties of the sequences enciphered under the proposed modification of the encryption-decryption algorithm.
