Implementation of a new chaotic encryption system and synchronization

Abstract A new kind of secure communication system which combines the chaotic encryption means with the conventional encryption method is discussed. With the analysis results and the experiment data, the anti-attack ability of this communication system is significantly improved compared to that of the either method. At the same time, a new method of chaotic synchronization is proposed. With a small mixed discrete chaotic signal, it is quickly to synchronize the communication and a good security performance is ensured.

Keystream cryptanalysis of a chaotic cryptographic method

Recently a new chaotic encryption system has been proposed as a modified version of the chaotic cryptographic method based on iterating a logistic map. A fundamental weakness of this new cryptosystem is pointed out that allows for three successful cryptanalytic attacks.

Cryptanalysis of a chaotic secure communication system

Recently a chaotic encryption system has been proposed by P. Garcı́a et al. It represents an improvement over an algorithm previously presented by some of the same authors. In this Letter, several weaknesses of the new cryptosystem are pointed out and four successful cryptanalytic attacks are described.
