“…In 2010, Fallahi K et al 10 proposed a secure chaotic spread spectrum communication scheme by using chaotic multiplication to modulate encrypted data and using an extended Kalman filter to accept data. In 2006, Lü et al 9 put forward the hyperchaotic Lü system on the basis of Lü system.…”

In the paper, a novel six-dimensional hyperchaotic system is proposed for secure communication. A detailed analysis of some relevant features, such as equilibrium stability, dissipation, bifurcation, and Lyapunov exponents. The resultsshow that there are hyperchaos, chaos, quasi-periodic, and periodic dynamic behaviors for our constructed hyperchaotic system. Then the six-dimensional hyperchaotic system is simulated and implemented, which verified its physical realizability. The six-dimensional hyperchaotic system is applied to complete the signal encryption and decryption circuit design, then the circuit is tested.The results indicate that the proposed hyperchaotic system can play an important role in some key areas such as communication security and complex systems.

“…4,5 Since Pecora et al 6 achieved the landmark study of synchronization between two chaotic systems in 1990, chaotic synchronization and its applications have attracted considerable attention. [7][8][9][10][11][12][13][14] In the previous studies, most of chaotic secure communication schemes are based on drive-response synchronization architecture, and various methods including chaotic masking, 15 chaos shift keying 16 and chaotic modulation 17 have been proposed.…”

In this paper, a novel digital secure communication scheme is¯rstly proposed. Di®erent from the usual secure communication schemes based on chaotic synchronization, the proposed scheme employs asynchronous communication which avoids the weakness of synchronous systems and is susceptible to environmental interference. Moreover, as to the transmission errors and data loss in the process of communication, the proposed scheme has the ability to be error-checking and error-correcting in real time. In order to guarantee security, the fractionalorder complex chaotic system with the shifting of order is utilized to modulate the transmitted signal, which has high nonlinearity and complexity in both frequency and time domains. The corresponding numerical simulations demonstrate the e®ectiveness and feasibility of the scheme.

“…Chaos has also been extensively studied in many fields, such as chemical reactions, power converters, biological systems, information processing, secure communications, etc. [1][2][3][4][5][6][7][8][9]. While many researchers analyze complicated, physically motivated configurations, there is also a need to investigate simple equations which may capture the essence of chaos in a less involved setting, thereby aiding the understanding of essential characteristics.…”

The history of the Lorenz system is firstly discussed in this paper. In Chinese philosophy, Yin is the negative, historical, or feminine principle in nature, while Yang is the positive, contemporary, or masculine principle in nature. Yin and Yan are two fundamental opposites in Chinese philosophy (therefore, in this paper, these words "Yin parameter," "Yang parameter," "historical system," and "contemporary system" are used to represent the "positive parameter," "negative parameter," "time reversed (−t) system," and "time forward (t) system," respectively). Simulation results show that chaos of historical Lorenz system can be generated when using "Yin" parameters. To our best knowledge, most characters of contemporary Lorenz system are studied in detail, but there are no articles in making a thorough inquiry about the history of Lorenz system. As a result, the chaos of historical Lorenz system with "Yin parameters" is introduced in this paper and various kinds of phenomena in the historical Lorenz system are investigated by Lyapunov exponents, phase portraits, and bifurcation diagrams.
