“…Variation of CSK method was proposed as in [18] where authors have tried to confuse the intruders by including some switching parameters. However, there are branches in RM if the RM is zoomed in as shown in [19]. Methods like [4] has also been proposed but broken easily later [16].…”

In this paper, a modified chaotic shift keying method is proposed to transmit digital bits securely over a communication channel. The scheme is based upon encrypting the digital bits 0 and 1 into infinite levels by applying the keystream such that there is no recognisable pattern in the encoded transmitted signal. The encoded transmitting signal generated is shown to resist popular attack method therefore realizing a secure and trustworthy digital communication system.

“…Famous features of the chaotic systems like strong dependence on the initial conditions, topological transitivity, wide spread spectrum of their signals, etc., directly suggested the idea of using chaotic systems to build up a new generation of the communication methods and to design the novel secure chaos-based communication schemes. Most of them are based on the synchronization of the chaotic systems [Materassi & Basso, 2008;Kocarev et al, 1992;Pecora & Carroll, 1990;Kolumbán et al, 1998]. Unfortunately the majority of the proposed methods are introduced without any cryptanalysis, they have rather weak security and they would be very likely broken later on [Li et al, 2005;Li et al, 2006;Perez & Cerdeira, 1995;Alvarez et al, 2004;Yang et al, 1998a;Short, 1994;Hu & Guo, 2008].…”

This paper focuses on the design of the novel chaotic masking scheme via message embedded synchronization. A general class of the systems allowing the message embedded synchronization is presented here, moreover, it is shown that the generalized Lorenz system belongs to this class. Furthermore, the secure encryption scheme based on the message embedded synchronization is proposed. This scheme injects the embedded message into the dynamics of the transmitter as well, ensuring thereby synchronization with theoretically zero synchronization error. To ensure the security, the embedded message is a sum of the message and arbitrary bounded function of the internal transmitter states that is independent of the scalar synchronization signal. The hexadecimal alphabet will be used to form a ciphertext making chaotic dynamics of the transmitter even more complicated in comparison with the transmitter influenced just by the binary step-like function. All mentioned results and their security are tested and demonstrated by numerical experiments.

Although many kinds of chaotic oscillators have been introduced, in electronics, Chua's circuit has been widely used because it allows the development of new designs and applications [Barboza & Chua, 2008;Bilotta et al, 2007;Cafagna & Grassi, 2004;Caponetto et al, 2005;Chua, 1994;Demirkol et al, 2008;Kilic, 2003;Tlelo-Cuautle & Muñoz-Pacheco, 2007;Yu et al, 2007].…”

This work shows the experimental implementation of a chaotic communication system based on two Chua's oscillators which are synchronized by Hamiltonian forms and observer approach. The chaotic communication scheme is realized by using the commercially available positive-type second generation current conveyor (CCII+), which is included into the AD844 device. As a result, experimental measurements are provided to demonstrate the suitability of the CCII+ to implement chaotic communication systems.
