Abstract

The paper presents a novel chaotic encryption algorithm which can be used to improve the communication security. An uncomplicated process of chaotic substitution permutation network (SPN) with variable control parameters is proposed to form a robust chaotic cryptosystem. A new chaotic generator, firstly proposed by Lozi, is used for this purpose. For the new cryptosystem, the results of the statistical NIST tests for pseudo-randomness showed to be successful. The system performances are significantly improved after a chaotic under-sampling of the output signal.
