摘要： This paper proposes a novel scalable digit-serial inverter structure with low space complexity to perform inversion operation in GF(2m) based on a previously modi?ed extended Euclidean algorithm. This structure is suitable for ?xed size processor that only reuse the core and does not require to modulate the core size when m modi?ed. This structure is extracted by applying a nonlinear methodology that gives the designer more ?exibility to control the processing element workload and also reduces the overhead of communication between processing elements. Implementation results of the proposed scalable design and previously reported ef?cient designs show that the proposed scalable structure achieves a signi?cant reduction in the area ranging from 83.0% to 88.3% and also achieves a signi?cant saving in energy ranging from 75.0% to 85.0% over them, but it has lower throughput compared to them. This makes the proposed design more suitable for constrained implementations of cryptographic primitives in ultra-low power devices such as wireless sensor nodes and radio frequency identi?cation (RFID) devices.

摘要： Real-time (RT) simulation is a highly reliable simulation method that is mostly based on electromagnetic transient simulation of complex systems comprising many domains. It is increasingly used in power and energy systems for both academic research and industrial applications. Due to the evolution of the computing power of RT simulators in recent years, new classes of applications and expanded fields of practice could now be addressed with RT simulation. This increase in computation power implies that models can be built more accurately and the whole simulation system gets closer to reality. This Task Force paper summarizes various applications of digital RT simulation technologies in the design, analysis, and testing of power and energy systems.

摘要： With its reprogrammability, low design cost, and increasing capacity, field-programmable gate array (FPGA) has become a popular design platform and a target for infringement. Currently available intellectual property (IP) protection solutions are usually limited to protect single FPGA configurations and require permanent secret key storage in the FPGA. In addition, they cannot provide a commercially popular pay-per-device licensing solution. In this paper, we propose a novel IP protection mechanism to restrict IP’s execution only on specific FPGA devices in order to efficiently protect IPs from being cloned, copied, or used with unauthorized integration. This mechanism can also enforce the pay-per-device licensing, which enables the system developers to purchase IPs from the core vendors at the low price based on usage instead of paying the expensive unlimited IP license fees. In our proposed binding-based mechanism, FPGA vendors embed into each enrolled FPGA device with a physical unclonable function (PUF) customized for FPGAs; IP vendors embed augmented finite-state machines (FSM) into the original IPs such that the FSM can be activated by the PUF responses from the FPGA device. We propose protocols to lock and unlock FPGA IPs, demonstrate how PUF can be embedded onto FPGA devices, and analyze the security vulnerabilities of our PUF-FSM binding method. We implement a 128-bit delay-based PUF on 28-nm FPGAs with only 258 RAM-lookup tables and 256 flipflops. The PUF responses are unique and reliable against environment changes. We also synthesize a variety of FSM benchmark circuits. On large benchmarks, the average timing overhead is 0.64% and power overhead in 0.01%.

Design and achievement of hardware-in-the-loop simulation system for strapdown semi-active laser seeker
摘要： According to the work characteristics of semi-active laser-guided weapon system, at first, the optical characteristics of the laser received by seeker were analyzed; and mathematical model of the optical signal power received by seeker was established. Secondly, a hardware-in-the-loop simulation(HILS) system was designed for strapdown seeker. In order to simulate energy and laser spot’s continuous variations, a high-precision continuous dynamic laser energy attenuation system and a digital micromirror device(DMD) spot projection system were designed respectively. In the end, the HILS system was used to evaluate the performances of strapdown seeker and the seeker was tested for response coherence among the four quadrants, field of view(FOV), linear field of view, minimum received optical power, and angle measurement accuracy.

Deep Learning Enabled Optimization of Downlink Beamforming Under Per-Antenna Power Constraints: Algorithms and Experimental Demonstration
摘要： Physical unclonable functions (PUFs) are increasingly used for authentication and identification applications as well as the cryptographic key generation. An important feature of a PUF is the reliance on minute random variations in the fabricated hardware to derive a trusted random key. Currently, most PUF designs focus on exploiting process variations intrinsic to the CMOS technology. In recent years, progress in emerging nanoelectronic devices has demonstrated an increase in variation as a consequence of scaling down to the nanoregion. To date, emerging PUFs with nanotechnology have not been fully established, but they are expected to emerge. Initial research in this area aims to provide security primitives for emerging integrated circuits with nanotechnology. In this paper, we review emerging nanotechnology-based PUFs.

摘要： Firstly, this paper analyzed in theory two kinds of frequency regulation control strategies, swing equation control strategy and additional frequency regulation characteristics control strategy, which were adopted by the demonstration project. The differences between two strategies in frequency modulation start-up time, oscillation risk, mode of supporting power, inertia response dead zone and so on were compared and studied. Then, relying on the recorded field data, paper showed the actual frequency modulation effect and characteristics of differences between the two strategies. Lastly, we optimized the VSG control strategies and proposed two new ones to make full ues of the available power of PV-VSG and coordination of photovoltaic and energy storage effectively to stable the grid frequency. The effectiveness of new control strategies was verified on a RT-LAB semi-physical simulation platform. This work is supported by science and technology project of the headquarter of State Grid Corporation of China.

摘要： Information security has emerged as an important system and application metric. Classical security solutions use algorithmic mechanisms that address a small subset of emerging security requirements, often at high-energy and performance overhead. Further, emerging side-channel and physical attacks can compromise classical security solutions. Hardware security solutions overcome many of these limitations with less energy and performance overhead. Nanoelectronics-based hardware security preserves these advantages while enabling conceptually new security primitives and applications. This tutorial paper shows how one can develop hardware security primitives by exploiting the unique characteristics such as complex device and system models, bidirectional operation, and nonvolatility of emerging nanoelectronic devices. This paper then explains the security capabilities of several emerging nanoelectronic devices: memristors, resistive random-access memory, contact-resistive random-access memory, phase change memories, spin torque-transfer random-access memory, orthogonal spin transfer random access memory, graphene, carbon nanotubes, silicon nanowire field-effect transistors, and nanoelectronic mechanical switches. Further, the paper describes hardware security primitives for authentication, key generation, data encryption, device identification, digital forensics, tamper detection, and thwarting reverse engineering. Finally, the paper summarizes the outstanding challenges in using emerging nanoelectronic devices for security.

[IEEE 2019 IEEE 46th Photovoltaic Specialists Conference (PVSC) - Chicago, IL, USA (2019.6.16-2019.6.21)] 2019 IEEE 46th Photovoltaic Specialists Conference (PVSC) - Comparison of Ideal Transformer Method and Damping Impedance Method for PV Power-Hardware-In-The-Loop Experiments
摘要： The Ideal Transformer Method (ITM) and the Damping Impedance Method (DIM) are the most widely used techniques for connecting power equipment to a Power-Hardware-in-the-Loop simulation. Both methods have been studied for their stability and accuracy in PHIL simulations, but neither have been analyzed when the hardware is providing grid-support services with volt-var, frequency-watt, and fixed power factor functions. In this work, we experimentally validate the two methods of connecting a physical PV inverter to a PHIL system and evaluate them for dynamic stability and accuracy when operating with grid-support functions. It was found that the DIM Low Pass Lead Filter (LPF LD) method was the best under unity and negative power factor conditions, but the ITM LPF LD method was preferred under positive power factor conditions.

摘要： This paper examines hardware trojan threats to semiconductor chips, which is particularly important for chips intended for vital infrastructure and critical applications. The phases of the chip production life-cycle are considered in terms of the opportunities for trojan insertion. Trojans are examined based on eight attribute categories. A matrix identifying the relationships between these attributes is defined. This matrix is used to characterize hardware trojans from both the attacker and defender perspectives. Two case studies are given to illustrate the usefulness of the proposed approach.
