“…From this point of view a fully digital chaotic, secure, communication scheme is presented in this paper. It has to be noted that a digital implementation as presented in this paper has distinct advantages over the normal analog or mixedsignal ones typically found in the literature: it is easier to interface with an already existing digital circuit, it is immune to the fabrication process variations, and its parameters and [11] BASED ON [9]). initial conditions can be fixed exactly to a desired value.…”

“…On the other hand, we have also performed a comparison of the implementation of this algorithm against those evaluated by NIST as the IoT encryption algorithm [9]. Specifically, we have compared the used memory and the time needed to encode a byte between all the finalists and our proposal when using the ESP32 implementation.…”

“…As far as lightweight implementations of secure data transmission are considered, it is mentioned the USA National Institute of Standards and Technology (NIST) launched in 2018 a call for the definition of requirements, selection process and the evaluation criteria of algorithms for constrained environments, where the performance of current NIST cryptographic standards is not acceptable [1]. These algorithms were evaluated both in hardware [8] and software [9] implementations. As a result of the process, the ASCON algorithm [10] was selected to be proposed as a standard for lightweigth encryption [11].…”

The two main issues in the area of the Internet of Things are low resource 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.

The U.S. National Institute of Standards and Technology is currently undertaking a process to evaluate and eventually standardize one or more "lightweight" algorithms for authenticated encryption and hashing that are suitable for resource-restricted devices. In addition to security, this process takes into account the efficiency of the candidate algorithms in various hardware environments (e.g. FPGAs, ASICs) and software platforms (e.g. 8, 16, 32-bit microcontrollers). However, while there exist numerous detailed benchmarking results for 8-bit AVR and 32-bit ARM/RISC-V/ESP32 microcontrollers, relatively little is known about the candidates' efficiency on 16-bit platforms. In order to fill this gap, we present a performance evaluation of the final-round candidates Ascon, Schwaemm, TinyJambu, and Xoodyak on the MSP430 series of ultra-low-power 16-bit microcontrollers from Texas Instruments. All four algorithms were explicitly designed to achieve high performance in software and have further in common that the underlying primitive is a permutation. We discuss how these permutations can be implemented efficiently in Assembly language and analyze how basic design decisions impact their execution time on the MSP430 architecture. Our results show that, overall, Schwaemm is the fastest algorithm across various lengths of data and associated data, respectively. Xoodyak has benefits when a large amount of associated data is to be authenticated, whereas TinyJambu is very efficient for the authentication of short messages.
