| 1 | Energy-Theft Detection Issues for Advanced Metering Infrastructure in Smart Grid显示文摘With the proliferation of smart grid research,the Advanced Metering Infrastructure(AMI) has become the first ubiquitous and fixed computing platform. However,due to the unique characteristics of AMI,such as complex network structure,resource-constrained smart meter,and privacy-sensitive data,it is an especially challenging issue to make AMI secure. Energy theft is one of the most important concerns related to the smart grid implementation. It is estimated that utility companies lose more than $25 billion every year due to energy theft around the world. To address this challenge,in this paper,we discuss the background of AMI and identify major security requirements that AMI should meet. Specifically,an attack tree based threat model is first presented to illustrate the energy-theft behaviors in AMI. Then,we summarize the current AMI energy-theft detection schemes into three categories,i.e.,classification-based,state estimation-based,and game theory-based ones,and make extensive comparisons and discussions on them. In order to provide a deep understanding of security vulnerabilities and solutions in AMI and shed light on future research directions,we also explore some open challenges and potential solutions for energy-theft detection. | Rong Jiang Rongxing Lu Ye Wang Jun Luo Changxiang Shen Xuemin(Sherman) Shen | 2014 | Tsinghua Science and Technology2014，19，2： | 22 |
| 2 | Designing efficient proxy signature schemes for mobile communication显示文摘Proxy signature is an active cryptographic research area,and a wide range of litera- tures can be found nowadays suggesting improvement and generalization of existing protocols in various directions.However,from the efficiency view,many proposed proxy signature schemes in these literatures are not satisfying and cannot fit to the mobile communication.Therefore,there is a desire to design efficient proxy sig- nature schemes.Based on Boneh et al's pairing-based short signature,this paper presents two proxy signature schemes.One is proxy-protected signature scheme, and the other is proxy aggregate signature scheme.Since both of them can achieve high efficiency,it is believed that they are specially suitable for mobile communica- tion environment. | LU RongXing DONG XiaoLei CAO ZhenFu | 2008 | Science in China(Series F)2008，51，2： | 9 |
| 3 | Provably secure robust threshold partial blind signature显示文摘Threshold digital signature and blind signature are playing important roles in cryptography as well as in practical applications such as e-cash and e-voting systems. Over the past few years, many cryptographic researchers have made considerable headway in this field. However, to our knowledge, most of existing threshold blind signature schemes are based on the discrete logarithm problem. In this paper, we propose a new robust threshold partial blind signature scheme based on improved RSA cryptosystem. This scheme is the first threshold partial blind signature scheme based on factoring, and the robustness of threshold partial blind signature is also introduced. Moreover, in practical application, the proposed scheme will be especially suitable for blind signature-based voting systems with multiple administrators and secure electronic cash systems to prevent their abuse. | CAO Zhenfu ZHU Haojin LU Rongxing | 2006 | Science in China(Series F)2006，49，5： | 5 |
| 4 | UMBRELLA: user demand privacy preserving framework based on association rules and differential privacy in social networks显示文摘Dear editor,The past several years have witnessed that people deeply rely on online services,such as shopping,transportation,and medical services.At the same time,privacy leakage has been a hot topic in social networks[1,2].Morever,the increasing applications of location based services(LBSs)indeed make our lives more convenient.However,LBSs also lead to significant privacy leakage.On the one hand,location information of a single point is sensitive.On the other hand,location trajec.tories can excavate more sensitive information despite location.In this regard,location privacy-preserving mechanisms have been extensively studied,such as Dunmiy,spatial confusion[3,4],encryption technology[5,6],differential privacy(DP)[7,8]and references therein. | Chunliu YAN Ziyi NI Bin CAO Rongxing LU Shaohua WU Qinyu ZHANG | 2019 | Science China(Information Sciences)2019，62，3： | 2 |
| 5 | MOF-Transformed In_(2)O_(3-x)@C Nanocorn Electrocatalyst for Efficient CO_(2)Reduction to HCOOH显示文摘For electrochemical CO_(2) reduction to HCOOH,an ongoing challenge is to design energy efficient electrocatalysts that can deliver a high HCOOH current density(JHCOOH)at a low overpotential.Indium oxide is good HCOOH production catalyst but with low con-ductivity.In this work,we report a unique corn design of In_(2)O_(3-x)@C nanocatalyst,wherein In_(2)O_(3-x)nanocube as the fine grains dispersed uniformly on the carbon nanorod cob,resulting in the enhanced conductivity.Excellent performance is achieved with 84%Faradaic efficiency(FE)and 11 mA cm^(−2)JHCOOH at a low potential of−0.4 V versus RHE.At the current density of 100 mA cm^(−2),the applied potential remained stable for more than 120 h with the FE above 90%.Density functional theory calculations reveal that the abundant oxygen vacancy in In_(2)O_(3-x) has exposed more In^(3+) sites with activated electroactivity,which facilitates the formation of HCOO*intermediate.Operando X-ray absorp-tion spectroscopy also confirms In^(3+) as the active site and the key intermediate of HCOO*during the process of CO_(2) reduction to HCOOH. | Chen Qiu Kun Qian Jun Yu Mingzi Sun Shoufu Cao Jinqiang Gao Rongxing Yu Lingzhe Fang Youwei Yao Xiaoqing Lu Tao Li Bolong Huang Shihe Yang | 2022 | Nano-Micro Letters2022，14，10： | 2 |
