Lightweight cryptography aims to address the security demands in resource-constrained hardware and software environments, such as the Internet of Things (IoT). These constraints severely limit solutions offered by conventional cryptographic primitives, which turn too expensive to achieve. In this paper, a lightweight pseudorandom number generator that fits the IoT demands is presented. It has a good...
A new automatic identification system, deployed for rubber tyred gantry (RTG) crane' applications, is designed based on a single and low-cost global positioning system (GPS) receiver. The new system is characterized by low cost, easy installation. However, the low-cost GPS receiver provides lower position accuracy, a new method that so-called “stack transition tracking” is present to improve the performances...
The following project is an attempt to popularize and implement the use of renewable and alternate sources of energy as opposed to nonrenewable energy sources like fossil fuels and biofuels. This project follows different approaches to harness energy. The first method harnesses solar energy by installing solar cells on an umbrella and using the power generated to charge mobile applications. The power...
A cryptographically secure hardware HTTP enabled random number generator based on a nondeterministic entropy source has been implemented using open source hardware development kit. Internally, randomness is distilled from the entropy source using Algorithm M where modified-RC4-based and BLAKE-512-as-counter-mode pseudo-random number stream generators are combined. Users access the device via HTTP...
The dual deterministic-stochastic behavior of chaotic systems (CS) makes them extremely interesting in electronic engineering as CS may replace noise sources in different applications. Consequently it is convenient to have hardware implementations for both, analog and digital versions. Discrete components, Micro Controllers, Digital Signal Processors (DSP) and Field Programmable Gate Arrays (FPGAs)...
Particle Swarm Optimization (PSO) algorithms have been proposed to solve engineering problems that require to find an optimal point of operation. However, the PSO algorithm suffers from premature convergence and high elapsed time when solving multimodal and large scale engineering problems. This problem becomes an evident drawback for embedded applications in which the microcontrollers often operates...
The use of distributed energy resources is increasing and represents a valid answer to environmental problems and to the significant costs of more traditional energy sources. The need of developing distributed energy systems is strictly related to the need of flexible and scalable high level controller, able to manage control references in order to optimise global system efficiency. This paper proposes...
According to the principle of magnetic field oriented vector control, an excitation vector controller of doubly-fed induction generator based on TMS320F2812 of TI Company is designed. With the analysis of the discipline of active power and reactive power decoupling control, the vector control technology to achieve active power and reactive power decoupling control is used, and the variable speed constant...
The hardware architecture and software designs of the digital fault recorder module are described in this paper. The enhanced MSCAN module and the XGATE co-processor of S12XD MCU are used to receive and manage the operate data through high-speed CAN bus. F-RAM is used as non-volatile data storage memory. The software, especially mentioned XGATE and fault data storage strategy, is discussed in detail...
