“…This setup is taking advantage of chaotic synchronization for modulating, encrypting, transmitting and retrieving information; thus establishing it as one demonstrating intrinsic security features, based on an unconventional approach, i.e., chaotic encryption. In the presented hereby approach, a fully digital communication system is implemented, by designing the digital circuits of a chaotic encoder/transmitter (its design, realization and study has been reported in [24]) and a decoder/receiver suitable for demodulating the chaotic-modulated information. The overall chaotic communication scheme appears in Fig.…”

The two main issues in the area of the Internet of Things are low resources consumption and secure data transmission. Conjugating both is fairly hard on ensuring security, leading to great efforts in research. The standard cryptography methods currently proposed are based on simplifications of standard protocols, but are still demanding on resources. Chaotic encryption is a way to reduce this burden, while keeping an equivalent level of security. In this paper, we propose, for the first time, a purely digital scheme for chaotic secure communications, able to be implemented in hardware or software without occupying most of the available resources. Next to the delivered analysis of the system, the experimental demonstration on both FPGA and ESP32 Arduino platforms of chaotic synchronization between transmitter and receiver, included examples of applied encrypted communication in the case of consecutive picture and text transmissions.

“…As already mentioned, a digital circuit having the ability of encoding by modulating and transmitting information over a chaotic carrier has been proposed and studied in [24]. This circuit is a non-autonomous, nonlinear, digital oscillator able to operate in a chaotic mode.…”

“…As a result, there exist numerous proposals in this sense, usually ubiquitous ones; one such promising option seems to lean towards using chaotic-based encoder-decoder schemes to secure and/or authenticate data transmission in general [13][14][15][16]. There are examples of such secure-communication systems, analog [17,18], and digital [19,20] ones demonstrating merits like low-cost, circuit simplicity, low-power operation etc. [9,10,21,22].…”

“…These features, especially sensitivity to initial conditions and parameter values, make proper implementation of chaotic systems within approximate computing frameworks, difficult, not impossible though. A successful example is the case of implementing a chaotic oscillator in a purely digital environment [20] but with the cost of creating a much more complicated (higher-dimensional) implementation.…”

Stochastic Computing Implementation of Chaotic Systems

An exploding demand for processing capabilities related to the emergence of the Internet of Things (IoT), Artificial Intelligence (AI), and big data, has led to the quest for increasingly efficient ways to expeditiously process the rapidly increasing amount of data. These ways include different approaches like improved devices capable of going further in the more Moore path but also new devices and architectures capable of going beyond Moore and getting more than Moore. Among the solutions being proposed, Stochastic Computing has positioned itself as a very reasonable alternative for low-power, low-area, low-speed, and adjustable precision calculations—four key-points beneficial to edge computing. On the other hand, chaotic circuits and systems appear to be an attractive solution for (low-power, green) secure data transmission in the frame of edge computing and IoT in general. Classical implementations of this class of circuits require intensive and precise calculations. This paper discusses the use of the Stochastic Computing (SC) framework for the implementation of nonlinear systems, showing that it can provide results comparable to those of classical integration, with much simpler hardware, paving the way for relevant applications.
