The Ukraine power grid cyberattacks remind us that the smart Internet of Things (IoT) can help us control our light-bulbs, but if under attacks it might also take us into darkness. Nowadays, many literatures have tried to address the concerns on IoT security, but few of them take into consideration the sever threats to IoT coming from the advances of quantum computing. As a promising candidate for the future post-quantum cryptography standard, lattice-based cryptography enjoys the advantages of strong security guarantees and high efficiency, which make it extremely suitable for IoT applications. In this paper, we summarize the advantages of lattice-based cryptography and the state of art of their implementations for IoT devices. Copyright © 2018, The Authors. All rights reserved.

As a unique biometric feature that can be recognized at a distance, gait has broad applications in crime prevention, forensic identification and social security. To portray a gait, existing gait recognition methods utilize either a gait template, where temporal information is hard to preserve, or a gait sequence, which must keep unnecessary sequential constraints and thus loses the flexibility of gait recognition. In this paper we present a novel perspective, where a gait is regarded as a set consisting of independent frames. We propose a new network named GaitSet to learn identity information from the set. Based on the set perspective, our method is immune to permutation of frames, and can naturally integrate frames from different videos which have been filmed under different scenarios, such as diverse viewing angles, different clothes/carrying conditions. Experiments show that under normal walking conditions, our single-model method achieves an average rank-1 accuracy of 95.0% on the CASIA-B gait dataset and an 87.1% accuracy on the OU-MVLP gait dataset. These results represent new state-of-the-art recognition accuracy. On various complex scenarios, our model exhibits a significant level of robustness. It achieves accuracies of 87.2% and 70.4% on CASIA-B under bag-carrying and coat-wearing walking conditions, respectively. These outperform the existing best methods by a large margin. The method presented can also achieve a satisfactory accuracy with a small number of frames in a test sample, e.g., 82.5% on CASIA-B with only 7 frames.

In this study, to solve technical problems such as bad wear abilities of hairy ramie spun yarn fabrics and the inconvenience of four-components' embeddable and locatable spinning system(denoted as ELS), this paper introduces a simplified embeddable and locatable spinning system(denoted as S-ELS) to produce smooth yarns of ramie fibers;then the smooth ramie yarns were knitted to obtain smooth fabrics. For a comparative study,three different ramie yarns were prepared by S-ELS, dry contact spinning of S-ELS and wet contact spinning of S-ELS;all the three type of yarns were knitted into fabrics respectively for the comparison of wearing performance. Results show that the wet contact spun S-ELS yarns had the least hairiness;knitted fabrics of wet contact spun S-ELS yarns had smoother surface, better permeability and higher mechanical properties than ELS as well as dry contact spun S-ELS yarns.

Microstructural parameters are important for analyzing the chemistry and performance of solid oxide fuel cells (SOFCs). Aiming at the YSZ / Ni anode optical microscopy (OM) image of SOFC, in this paper, particle swarm intelligent optimization algorithm is used to improve the fuzzy C-means clustering algorithm for image segmentation. Particle swarm optimization is used to adaptively search the initial clustering center, helping to avoid local optimization and preserve more image detail. The experimental results show that the proposed method can improve the segmentation accuracy of images. At the same time, it can accurately segment the SOFC three-phase and provide effective image segmentation results for the microstructure parameters.

Differential evolution（DE） is an excellent global optimizer, which has been used to optimize various engineering problems. In recent years, the radio frequency identification technology（RFID） has been applied to many fields. However, it is not an easy task to design an efficient RFID antenna. The antenna structure is usually complex and it is difficult to find a suitable parameter set. In this paper, we try to use DE to design a RFID antenna with Fibonacci sequence quasi Yagi structure. Simulation results show that DE can successfully design the antenna. The obtained antenna size is 30 mm × 20 mm. Its simulation center frequency is 60 GHz and the center frequency gain approximates 8 dB. In the frequency band 59.5-60.5 GHz, the frequency echo loss is less than-10 dB and the minimum value is-111 dB.

This paper focuses on the scheme of cooperative lane change motion planning of multiple connected and automated vehicles, so as to minimize the time for lane change while penalizing large steering angles subject to hard collision avoidance constraints. Nominally this scheme should be formulated in a centralized way with the constraints of all the vehicles considered simultaneously. In order to facilitate the numerical solving process of this centralized optimization problem, we propose a stepwise computation framework. Starting with a sub-problem with all of the collision avoidance constraints removed, a sequence of sub-problems are defined by adding back the removed collision avoidance constraints gradually until the original problem takes shape in the end. The optimum of one sub-problem is always used as the initial guess when solving the next sub-problem. This iterative process continues until the optimum of the original problem is obtained. In this way, the difficulties in the original centralized problem are divided into multiple parts, and every progress made to address the partial difficulties is 'solidified' by the initial guess. © 2018 IEEE.
