3Efficient Protocols for the General Millionaires' Problem显示文摘Secure multiparty computation(SMC) is a research focusing in the international cryptographic community. The protocols used to address the millionaires' problem are the basic building blocks of most SMC protocols and their efficiency dominates that of many other SMC protocols. To the best of our knowledge, almost all protocols used to address the millionaires' problem are based on integers, which means that their applications are limited. In this study, we propose precise and efficient protocols for rational numbers based on additively homomorphic encryptions. One of our protocols is inspired by computational geometry and it reduces the millionaires' problem to computing the area of a triangle formed by three private points. This approach can determine whether the relationship between two private inputs is greater than, equal to or less than, and it has a much lower computational complexity compared with existing methods. We proved that these protocols are secure using simulation paradigm. Our approaches can be used in many SMC protocols that involve rational numbers and integers, and they can also be used directly to solve some secure multiparty computational geometry problem in rational number field.LI Shundong GUO Yimin ZHOU Sufang DOU Jiawei WANG Daoshun 2017Chinese Journal of Electronics2017,26,4:8
4Symmetric cryptographic protocols for extended millionaires’ problem显示文摘Yao’s millionaires’ problem is a fundamental problem in secure multiparty computation, and its solutions have become building blocks of many secure multiparty computation solutions. Unfortunately, most protocols for millionaires’ problem are constructed based on public cryptography, and thus are inefficient. Furthermore, all protocols are designed to solve the basic millionaires’ problem, that is, to privately determine which of two natural numbers is greater. If the numbers are real, existing solutions do not directly work. These features limit the extensive application of the existing protocols. This study introduces and refines the first symmetric cryptographic protocol for the basic millionaires’ problem, and then extends the symmetric cryptographic protocol to privately determining which of two real numbers is greater, which are called the extended millionaires’ problem, and proposes corresponding protocols. We further prove, by a well accepted simulation paradigm, that these protocols are private. Constructed based on symmetric cryptography, these protocols are very efficient.LI ShunDong WANG DaoShun DAI YiQi 2009Science in China(Series F)2009,52,6:8

6TWO PRIVACY-PRESERVING PROTOCOLS FOR POINT-CURVE RELATION显示文摘Numerous privacy-preserving issues have emerged along with the fast development of Internet, both in theory and in real-life applications. To settle the privacy-preserving problems, secure multi-party computation is essential and critical. In this paper, we have solved two problems regarding to how to determine the position relation between points and curves without revealing any private information. Two protocols have been proposed in order to solve the problems in different conditions. In addition, some building blocks have been developed, such as scalar product protocol, so that we can take advantage of them to settle the privacy-preserving computational geometry problems which are a kind of special secure multi-party computation problems. Moreover, oblivious transfer and power series expansion serve as significant parts in our protocols. Analyses and proofs have also been given to argue our conclusion.Liu Liang Wu Chunying Li Shundong 2012Journal of Electronics(China)2012,29,5:6
7Secure multi-party computation solution to Yao's millionaires' problem based on set-inclusion显示文摘Secure multi-party computation is a focus of international cryptography in recent years. Protocols for Yao’s millionaires’ problem have become an important building block of many secure multi-party computation protocols. Their efficiency are crucial to the efficiency of many secure multi-party computation protocols. Unfortunately, known protocols for Yao’s millionaires’ problem have high computational complexity or communication complexity. In this study, based on the 1-out-of-m oblivious transfer and set-inclusion problem, we propose a new protocol to solve this problem. This new protocol is very efficient in terms of both computational and communication complexities. Its privacy-preserving property is also proved by simulation paradigm which is generally accepted in the study of secure multi-party computation. We also compare the information leakage of our new protocol and the known protocols.LI Shundong DAI Yiqi YOU Qiyou 2005Progress in Natural Science:Materials International2005,15,9:4

9Comparing two sets without disclosing them显示文摘Secure multiparty computation has become a central research focus in the international cryptographic community. Secure comparing two sets is an important problem in secure multiparty computation. The research on privately determining whether two sets are equal has not been investigated. This study solves the problem by mapping these sets into natural numbers and then comparing corresponding numbers. We propose two secure multiparty computation protocols for comparing two sets. It is proved by well-accepted simulation paradigm that these solutions are private in semi-honest model. These solutions have important significance in constructing other secure multiparty computation protocols.LI ShunDong DAI YiQi WANG DaoShun LUO Ping 2008Science in China(Series F)2008,51,9:3
10Region Incrementing Visual Cryptography Scheme with Same Contrast显示文摘In binary Region incrementing visual cryptography schemes(RIVCSs),the secrets of multiple secrecy regions can be gradually revealed by human visual system.A characteristic of the existing binary RIVCSs different from traditional binary Visual cryptography schemes(VCSs) is that,the contrasts for different revealed regions are different while traditional binary VCSs have same contrast.To keep the quality(contrast) of recovered image compatible with the traditional VCS,we use integer linear programming to design a binary(k,n)-RIVCS with same contrast for all secrecy regions in this paper.Experimental results demonstrate that our method is feasible and effective.The trade-off is that our scheme involves a larger pixel expansion.LI Shundong LI Jiliang WANG Daoshun 2016Chinese Journal of Electronics2016,25,4:2

12Piezoelectric properties of low loss and high Curie temperature (Bi, La)FeO_3-Pb(Ti, Mn)O_3 ceramics with Mn doping显示文摘Piezoelectric ceramics of 0.6(Bi0.9La0.1)FeO3-0.4Pb(Ti1-xMnx)O3 (BLF-PTM) for x=0, 0.01, 0.02, and 0.03 were prepared by sol-gel process combined with a solid-state reaction method. The tan? for BLF-PTM of x=0.01 is just 0.006 at 1 kHz, drastically decreasing by using Mn dopants. The TC increases to 490 ℃ for BLF-PTM of x=0.02. Furthermore, Mn modification effectively enhances the poling state and the piezoelectric properties of BLF-PTM. The kp, Qm, d33, and g33 of 0.34, 403, and 124 pC1·N-1 and 37×10-3 Vm·N-1 are achieved for BLF-PTM of x=0.01. The results indicate that Mn modified BLF-PTM is a competitive high power and high temperature piezoelectric material with excellent piezoelectric properties.SHI Guiyang, WANG Dalei, BU Shundong, JIN Dengren, and CHENG Jinrong School of Materials Science and Engineering, Shanghai University, Shanghai, 200072, China 2012Rare Metals2012,31,6:2
13Tumor microenvironment responsive drug delivery systems显示文摘Conventional tumor-targeted drug delivery systems(DDSs)face challenges,such as unsatisfied systemic circulation,low targeting efficiency,poor tumoral penetration,and uncontrolled drug release.Recently,tumor cellular molecules-triggered DDSs have aroused great interests in addressing such dilemmas.With the introduction of several additional functionalities,the properties of these smart DDSs including size,surface charge and ligand exposure can response to different tumor microenvironments for a more efficient tumor targeting,and eventually achieve desired drug release for an optimized therapeutic efficiency.This review highlights the recent research progresses on smart tumor environment responsive drug delivery systems for targeted drug delivery.Dynamic targeting strategies and functional moieties sensitive to a variety of tumor cellular stimuli,including pH,glutathione,adenosine-triphosphate,reactive oxygen species,enzyme and inflammatory factors are summarized.Special emphasis of this review is placed on their responsive mechanisms,drug loading models,drawbacks and merits.Several typical multi-stimuli responsive DDSs are listed.And the main challenges and potential future development are discussed.Qunye He Jun Chen Jianhua Yan Shundong Cai Hongjie Xiong Yanfei Liu Dongming Peng Miao Mo Zhenbao Liu 2020Asian Journal of Pharmaceutical Sciences2020,15,4:2
