Since its introduction by the National Cryptography Administration in 2016, the SM9 algorithm has encountered various opportunities and challenges. This study introduces a refined bottom-up modular framework, resulting in a more systematic and comprehensible algorithm structure with standardized naming conventions and clear module component descriptions. At the same time, we have proposed a comprehensive optimization scheme for bilinear pairing, optimizing the internal calculation process and improving the usability and efficiency of the SM9 algorithm. The experimental results at both the software and hardware levels have confirmed the effectiveness of our proposed method. Our work goes beyond previous research that mainly focuses on individual modules or sub-modules, and has made significant progress in promoting the widespread application of the SM9 algorithm in practical scenarios. © 2025 SPIE.

Automotive Grade chips need to take into account the effects of unintended failures during operation, such as open circuits caused by chip aging or flipped memory devices caused by particle bombardment. Therefore, in the design process of automotive-grade chips, it is necessary to evaluate their safety and reliability. In this paper, we analyze the failure sources of automotive-grade chips and classify them according to the failure modes, comprehensively consider the impacts of different safety mechanisms, qualitatively and quantitatively analyze the functional safety of automotive-grade chips under transient failures, and quantify the level of protection against failures of automotive-grade chips under the transient failure conditions by means of mathematical models and evaluation indexes. The experimental results prove that it is feasible to evaluate the safety of the vehicle-grade chip through the functional safety analysis method at the design stage, and verify the protective effect of the safety mechanism of the chip on the vehicle-grade chip, which can guide the work of the vehicle-grade chip designers. © 2025 SPIE.

Introducing electric and thermal energy storage into Combined Cooling, Heating, and power (CCHP) systems can greatly reduce dependence on fossil fuels and significantly decrease greenhouse gas emissions. This study proposes a distributed collaborative optimization operational strategy for integrated energy systems in industrial parks based on a leader-follower game framework. In this approach, the integrated energy seller serves as the leader. At the same time, new energy-based CCHP operators and load aggregators act as followers, working out their interaction strategies to achieve optimal objectives. First, the mathematical model of the industrial park's integrated energy system is presented and embedded within a leader-follower game framework that incorporates tiered carbon trading and demand response, thereby establishing a one‑leader-multiple-followers distributed collaborative optimization model. Second, an improved Integrated Arctic Puffin (IAPO) optimization method is combined with the CPLEX solver to determine the optimal layout and operational plan for the developed optimization model. Finally, case studies validate the effectiveness of the proposed method, demonstrating that both the supply-side revenue and the demand-side consumer surplus are enhanced. The case study results indicate that the proposed two-tier optimization model achieves significant improvements of 10.47 % and 16.18 % in economic and environmental performance, respectively. In comparison, the storage systems' charge-discharge cycle depth and effective capacity utilisation rate are improved by 17.21 % and 21.85 %, respectively. © 2025 Elsevier Ltd

The thermal characteristics of insulated gate bipolar transistor (IGBT) module is attracted much attention, since the production consistency and reliability are affected when IGBT works in high temperature environment. Transient thermal impedance is better than steady-state thermal resistance for thermal characterization of the IGBT due to the reason that the IGBT mostly operates in pulsed current mode rather than in DC mode or continuous current mode. In this paper, a simple equivalent circuit is proposed and built in MATLAB Simulink for rapid reproduction of IGBT transient thermal impedance graph given in production datasheets. The reproduced transient thermal impedance graph can help engineers to calculate the current limit of a semiconductor device for different pulse durations. © 2023 IEEE.

Zener diode is widely used in IC design, and its breakdown voltage is an important electrical parameter. However, since the Zener diode has been designed and optimized through the use of a design of experiment (DOE) approach based on TCAD simulations, a large amount of I-V characteristics curves are generated, and then processed by manual method for extracting the breakdown voltages, which is time consuming and error prone. In this paper, a novel numerical method is proposed, mainly including data filling, data smoothing, and anomaly detection. It is successfully applied to automatically extract the breakdown voltages with low human intervention and excellent repeatability. © 2023 IEEE.

Central Processing Unit (CPU), as one of the core devices in electronic equipment, whether it can operate safely and reliably directly affects the safety of the entire electronic equipment. However, the electronic equipment manufacturers concern much more about the functional safety of System on chip (SoC), for the functional safety of the CPU there is no an independent and systematic solution. During the CPU design process, structure of redundant hardware and software diagnosis technology are used to reduce the random hardware failures. By using the systematic solution, the CPU can prevents unsafe states and reduce the probability of harmful events, and easily achieve SIL2 and SIL3 safety goal. © 2020 ACM.

Aiming to explore the passive micro sensor for SF6 detection, the proposed method is about designation and structure of SF6 detection micro sensor with high signal-to-noise ratio, miniaturization and passivity. Advanced micro-machining technology is presented to sharply reduce the volume of the sensor, where the volume can be reduced by more than 50% compared with the existing sensor with discrete combination. The cost and volume reduction does not only make the new detection equipment possible, but the energy consumption of the whole system will also be greatly reduced. The application and promotion of the passive micro sensor in ring network cabinet, GIS, GIL and cable channel can bring considerable economic benefits. © 2019 IEEE.
