| 1 | Extended multivariate public key cryptosystems with secure encryption function显示文摘Advances in quantum computers pose great threats on the currently used public key cryptographic algorithms such as RSA and ECC. As a promising candidate secure against attackers equipped with quantum computational power, multivariate public key cryptosystems (MPKCs) have attracted increasing attention in recently years. Unfortunately, the existing MPKCs can only be used as a multivariate signature scheme, and it remains unknown how to construct an efficient MPKC enabling secure encryption. Furthermore, some multivariate signature schemes have been shown insecure in recent years, and it is also not trivial to build MPKC which can serve as a secure signature scheme. By employing the basic MQ-trapdoors, this paper proposes a novel MPKC and shows how it can be used as a multivariate signature scheme and a multivariate encryption scheme, respectively. The goal is achieved by incorporating our new hash authentication techniques and some modification methods such as the Shamir's minus method. Thorough analysis shows that our schemes are secure and efficient. Our MPKC gives a positive response to the challenges in multivariate public key cryptography. | WANG HouZhen 1,2 , ZHANG HuanGuo 1,2 , WANG ZhangYi 1,2 & TANG Ming 1,2 1 The Key Laboratory of Aerospace Information Security and Trusted Computing, Ministry of Education, School of Computer, Wuhan University, Wuhan 430079, China 2 State Key Laboratory of Software Engineering, Wuhan University, Wuhan 430072, China | 2011 | Science China(Information Sciences)2011，54，6： | 26 |
| 2 | Multiparty simultaneous quantum identity authentication with secret sharing显示文摘Two multiparty simultaneous quantum identity authentication (MSQIA) protocols based on secret sharing are presented. All the users can be authenticated by a trusted third party (TTP) simultaneously. In the first protocol,the TTP shares a random key K with all the users using quantum secret sharing. The ith share acts as the authentication key of the ith user. When it is necessary to perform MSQIA,the TTP generates a random number R secretly and sends a sequence of single photons encoded with K and R to all the users. According to his share,each user performs the corresponding unitary operations on the single photon sequence sequentially. At last,the TTP can judge whether the impersonator exists. The sec-ond protocol is a modified version with a circular structure. The two protocols can be efficiently used for MSQIA in a network. They are feasible with current technol-ogy. | YANG YuGuang1,2,WEN QiaoYan3 & ZHANG Xing4,5 1 College of Computer Science and Technology,Beijing University of Technology,Beijing 100022,China 2 State Key Laboratory of Information Security (Graduate University of the Chinese Academy of Sciences),Beijing 100049,China 3 School of Science,Beijing University of Posts and Telecommunications,Beijing 100876,China 4 Institute of Electronic Technology,Information Engineering University,Zhengzhou 450004,China 5 Trusted Computing Laboratory,Beijing University of Technology,Beijing 100022,China | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，3： | 12 |
| 3 | Capability of evolutionary cryptosystems against differential cryptanalysis显示文摘The evolutionary cryptosystem is a new cryptosystem.This paper studies its security level resisting against differential cryptanalysis.It is shown that the evolutionary cryptosystem possesses higher resistance than its initial fixed cryptosystem against differential cryptanalysis.On the basis of the relationship among the data complexity,the bit advantage and the success rate of differential cryptanalysis,it is proven that more data is needed for attacking the evolutionary cryptosystem when the bit advantage and success rate are identical.Moreover,it is shown that the time complexity for attacking the evolutionary cryptosystem is higher than that of differential attacking its initial fixed cryptosystem with the same amount of plaintext-ciphertext pairs.The research indicates that the evolutionary cryptosystem is more robust than its initial fixed cryptosystem against differential cryptanalysis. | ZHANG HuanGuo 1,2 ,LI ChunLei 1,2 & TANG Ming 1,2 1 School of Computer,Wuhan University,Wuhan 430072,China 2 Key Laboratory of Aerospace Information Security and Trusted Computing of Ministry of Education,Wuhan University,Wuhan 430072,China | 2011 | Science China(Information Sciences)2011，54，10： | 11 |
| 4 | Research on theory and key technology of trusted computing platform security testing and evaluation显示文摘Trusted computing has become a new trend in the area of international information security, and the products of trusted computing platform begin to be used in application. Users will not use the products of information security, unless it goes through the testing and evaluation. Here we concentrate on the testing and evaluation problem of trusted computing platform, begin with constructing proper formalization model of trusted computing platform for testing, and establish a mathematical chain of trust model based on SPA. Moreover, we give a verification method of composite characteristics and find the potential factors threatening the trusted system in the process of remote attestation through analysis. For trusted software stack, we study the problem of automatic generation of test case and propose an improved method of generating the random test case, to raise the quality of test case. Finally, we give a prototype system of trusted computing platform and the actual test data related. The result demonstrates that there exist some flaws in the architecture of the present TCG computing platform. At the same time, some flaws are found in the products of existing trusted computing platform, thus a basis is laid for the improvement and development of trusted platform technology and its products. | ZHANG HuanGuo1,2, YAN Fei1,2, FU JianMing1,2, XU MingDi1,2, YANG Yang1,2, HE Fan1,2 & ZHAN Jing1,2 1School of Computer, Wuhan University, Wuhan 430072, China 2Key Laboratory of Aerospace Information Security and Trusted Computing, Ministry of Education, Wuhan 430072, China | 2010 | Science China(Information Sciences)2010，53，3： | 11 |
| 5 | Arsenic trioxide promotes mitochondrial DNA mutation and cell apoptosis in primary APL cells and NB4 cell lines显示文摘This study aimed to investigate the effects of arsenic trioxide(As2O3) on the mitochondrial DNA(mtDNA) of acute promyelocytic leukemia(APL) cells.The NB4 cell line was treated with 2.0 μmol/L As2O3 in vitro,and the primary APL cells were treated with 2.0 μmol/L As2O3 in vitro and 0.16 mg kg-1 d-1 As2O3 in vivo.The mitochondrial DNA of all the cells above was amplified by PCR,directly sequenced and analyzed by Sequence Navigatore and Factura software.The apoptosis rates were assayed by flow cytometry.Mitochondrial DNA mutation in the D-loop region was found in NB4 and APL cells before As2O3 use,but the mutation spots were remarkably increased after As2O3 treatment,which was positively correlated to the rates of cellular apoptosis,the correlation coefficient:rNB4-As2O3=0.973818,and rAPL-As2O3=0.934703.The mutation types include transition,transversion,codon insertion or deletion,and the mutation spots in all samples were not constant and regular.It is revealed that As2O3 aggravates mtDNA mutation in the D-loop region of acute promyelocytic leukemia cells both in vitro and in vivo.Mitochondrial DNA might be one of the targets of As2O3 in APL treatment. | MENG Ran1,ZHOU Jin2,SUI Meng3,LI ZhiYong4,FENG GuoSheng1 & YANG BaoFeng2 1 Division of Neurology,the Ninth Clinical Medical College of Beijing University(Shijitan Hospital),Beijing 100038,China 2 The First Hospital of Harbin Medical University,Harbin 150001,China 3 Management Information System,University of International Business and Economics,Beijing 100029,China 4 Department of Radiology,Cambridge University Hospitals NHS Foundation Trust Box 219 Level 5,Addenbrooke’s Hospital Cambridge CB2 0QQ,UK | 2010 | Science China(Life Sciences)2010，53，1： | 10 |
