Bottom Line: The key signal is also encrypted using the same logistic map with different initial conditions.In the receiver side, the binary-coded message is decrypted using the encrypted key signal that is sent through one of the communication channels.The proposed scheme is experimentally tested using Arduino shields which are simple yet powerful development kits that allows for the implementation of the communication system for testing purposes.

ABSTRACT
Security and secrecy are some of the important concerns in the communications world. In the last years, several encryption techniques have been proposed in order to improve the secrecy of the information transmitted. Chaos-based encryption techniques are being widely studied as part of the problem because of the highly unpredictable and random-look nature of the chaotic signals. In this paper we propose a digital-based communication system that uses the logistic map which is a mathematically simple model that is chaotic under certain conditions. The input message signal is modulated using a simple Delta modulator and encrypted using a logistic map. The key signal is also encrypted using the same logistic map with different initial conditions. In the receiver side, the binary-coded message is decrypted using the encrypted key signal that is sent through one of the communication channels. The proposed scheme is experimentally tested using Arduino shields which are simple yet powerful development kits that allows for the implementation of the communication system for testing purposes.

Mentions: As can be seen in the bifurcation diagram, there are different regions that depend on the value of r. It is of particular interest when r = 3 because there it begins the period doubling that leads to the chaotic dynamics when r ≈ 3.5699… until r = 4.0. Figure 3 shows the Lyapunov exponent of the logistic map as r is varied from 2.5 to 4.0. It can be seen that the Lyapunov exponent, λ, becomes positive for values of approximately greater than 3.56 which is a strong indicator of chaos [33].
