With the advent of worldwide networks and digital communication techniques, the cryptographic techniques that once were restricted to military and state affairs are now covering several domains such as banks, private companies, medical organizations, and so forth. Security and secrecy in communications are some of the most important concerns in societies nowadays. ![]() 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. 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 key signal is also encrypted using the same logistic map with different initial conditions. The input message signal is modulated using a simple Delta modulator and encrypted using a logistic map. 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. 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 the last years, several encryption techniques have been proposed in order to improve the secrecy of the information transmitted. Security and secrecy are some of the important concerns in the communications world.
