| 1 | Alliance-Authentication Protocol in Clouds Computing Environment显示文摘Security has been regarded as one of the hardest problems in the development of cloud computing. This paper proposes an Alliance-Authentication protocol among Hybrid Clouds that include multiple private clouds and/or public clouds. Mutual authentication protocol among entities in the Intra-Cloud and Inter-Cloud is proposed. Blind signature and bilinear mapping of automorphism groups are adopted to achieve the Inter-Cloud Alliance-Authentication, which overcome the complexity of certificate transmission and the problem of communication bottlenecks that happen in traditional certificate-based scheme. Blind key, instead of private key, is adopted for register, which avoids the unauthorized Key Management Center (KMC) faking the members to access the resources in traditional identity-based scheme. Compared with the traditional scheme, our scheme can also achieve anonymity, traceability and privacy protection. Extensive security and performance analysis show that the proposed schemes have an advantage in security, computation consumption and communication consumption. | Zhang Qikun Li Yuanzhang Song Danjie Tan Yuan | 2012 | China Communications2012，9，7： | 7 |
| 2 | Driver-automation shared steering control for highly automated vehicles显示文摘A model predictive control(MPC)-based shared steering framework for intelligent vehicles is proposed in this paper.The road boundary and vehicle stability boundary are regarded as the safe envelope,and the tradeoff between the freedom of driver operation and safety assurance of intelligent vehicles is made within this safe envelope.Under this cooperative steering framework,the reliability of drivers is analyzed in dangerous situations and in the predictive time domain,and two improved schemes are proposed.Under the two improved schemes,the weight of the control objective can be adaptively changed according to the results of the threat assessment and predetermined strategy.At the same time,an evaluation index named control intervention rate and risk rate is proposed to evaluate the designed human-vehicle cooperation scheme.The simulation results show that the performance of the two improved schemes in ensuring the safety of intelligent vehicles has been improved. | Jun LIU Hongyan GUO Linhuan SONG Qikun DAI Hong CHEN | 2020 | Science China(Information Sciences)2020，63，9： | 6 |
| 3 | Growth Characteristics and Kinetics of Niobium Carbide Coating Obtained on AISI 52100 by Thermal-reactive Diffusion Technique显示文摘Niobium carbide coating was produced by thermal-reactive diffusion technique on AISI 52100 steel in salt bath at 1 123 K, 1 173 K, and 1 223 K for 1, 2, 4, and 6 hours. The salt consisted of borax, sodium fl uoride, boron carbide, and niobium pentoxide. The presence of NbC phase on the steel surface was confi rmed by X-ray diffraction analysis. Microscopic observation showed that niobium carbide coating formed on the substrate was smooth and compact. There was a distinct and fl at interface between the coating and substrate. The micro-hardness of niobium carbide coating was 2892±145HV. The thickness of coating ranged from 1.6 μm to 14μm. The forming kinetics of niobium carbide coating was revealed. Moreover, a contour diagram derived from experimental data was graphed for correct selection of process parameters. Some mathematical equations were built for predicting the coating thickness with predetermined processing temperature and time. The results showed that these mathematical equations are very practical as well as the kinetics equation. | 严绍进 王洪福 SUN Qikun HE Peng PANG Chengang WANG Huachang WANG Ailing | 2014 | Journal of Wuhan University of Technology(Materials Science)2014，29，4： | 5 |
| 4 | Blockchain-Based Dynamic Group Key Agreement Protocol for Ad Hoc Network显示文摘Group key agreement(GKA)is one of the key technologies for ensuring information exchange security among group members.While GKA is widely used in secure multi-party computation,safety of resources sharing,and distributed collaborative computing.It still has some security flaws and limitations.We proposes a Blockchain-based dynamic Group key agreement(BDGKA)protocol.In contrast to prior works,BDGKA differs in several significant ways:1)anonymous identity authentication-it can prevent privacy leaks;2)traceability-it can track illegal operating entities;3)load balancing-it balances computation and communication to each node,avoiding the breakdown of single-point and network bottlenecks.This protocol is proven secure under the hardness assumption of decision bilinear DiffieHellman.The performance analysis shows that it is more efficient than the referred works. | ZHANG Qikun WANG Bingli ZHANG Xiaosong YUAN Junling WANG Ruifang | 2020 | Chinese Journal of Electronics2020，29，3： | 5 |
| 5 | Atomically Smooth Ultrathin Films of Topological Insulator Sb_(2)Te_(3)显示文摘The growth and characterization of single-crystalline thin films of topological insulators(TIs)is an important step towards their possible applications.Using in situ scanning tunneling microscopy(STM)and angle-resolved photoemission spectroscopy(ARPES),we show that moderately thick Sb_(2)Te_(3)films grown layer-by-layer by molecular beam epitaxy(MBE)on Si(111)are atomically smooth,single-crystalline,and intrinsically insulating.Furthermore,these films were found to exhibit a robust TI electronic structure with their Fermi energy lying within the energy gap of the bulk that intersects only the Dirac cone of the surface states.Depositing Cs in situ moves the Fermi energy of the Sb_(2)Te_(3)films without changing the electronic band structure,as predicted by theory.We found that the TI behavior is preserved in Sb_(2)Te_(3)films down to five quintuple layers(QLs). | Guang Wang Xiegang Zhu Jing Wen Xi Chen Ke He Lili Wang Xucun Ma Ying Liu Xi Dai Zhong Fang Jinfeng Jia Qikun Xue | 2010 | Nano Research2010，3，12： | 5 |

| 8 | Preparation and characterization of solidified oleanolic acid–phospholipid complex aiming to improve the dissolution of oleanolic acid显示文摘The purpose of this study was to prepare the oleanolic acid–phospholipid complex (OAPC) and then solidify it employing fumed silica by simple solvent evaporation technique to improve dissolution rate of oleanolic acid and oleanolic acid–phospholipid complex. The process of OA-PC was optimized and the type and proportion of fumed silica were studied by dissolution text. The structures of the phospholipid complex and solidified powder were also characterized by differential scanning calorimetry, X-ray diffraction, and scanning electron microscope. In the dissolution tests, OA from solidified powder was further released compared with that from pure OA and OA-PC in different kinds of dissolution media. These results suggest that the method of preparing solidified powder of oleanolic acid–phospholipid complex is suitable for enhancing the dissolution rate of OA and OA-PC. | Xiaoxu Yang Qikun Jiang Ping Du Juanhang Zhao Tianhong Zhang | 2016 | Asian Journal of Pharmaceutical Sciences2016，11，2： | 4 |

| 10 | Decentralized model reference adaptive sliding mode control based on fuzzy model显示文摘A new design scheme of decentralized model reference adaptive sliding mode controller for a class of MIMO nonlinear systems with the high-order interconnections is proposed. The design is based on the universal approximation capability of the Takagi-Seguno (T-S) fuzzy systems. Motivated by the principle of certainty equivalentcontrol, a decentralized adaptive controller is designed to achieve the tracking objective without computation of the T-S fuzz ymodel. The approach does not require the upper bound of the uncertainty term to be known through some adaptive estimation.By theoretical analysis, the closed-loop fuzzy control system is proven to be globally stable in the sense that all signalsinvolved are bounded, with tracking errors converging to zero. Simulation results demonstrate the effectiveness of the approach. | Gu Haijun Zhang Tianping Shen Qikun | 2006 | Journal of Systems Engineering and Electronics2006，17，1： | 4 |
| 11 | An Authenticated Asymmetric Group Key Agreement for Imbalanced Mobile Networks显示文摘A Group key agreement(GKA) protocol enables a group of communicating parties to negotiate a common secret key over an open, untrusted network. The design goal of GKA is to achieve secure group communication, which is an important research issue for mobile communication. The conventional(symmetric) GKA protocol allows a group of members to establish a common secret key for imbalanced mobile networks. However, only the group members can broadcast secret message to the group. To overcome this limitation, this paper proposes an authenticated asymmetric GKA protocol. Instead of a common secret key, each group member negotiates a common group public key and holds a different decryption key. The paper proposed protocol supports the dynamic nodes update of mobile networks, which has forward secrecy and backward secrecy of group key. This protocol is proven secure under the Bilinear Computational Diffie–Hellman problem assumption and the performance analysis shows that the proposed scheme is highly efficient. | ZHANG Qikun ZHANG Quanxin MA Zhongmei TAN Yu'an | 2014 | Chinese Journal of Electronics2014，23，4： | 4 |

| 16 | An Identity-Based Proxy Signature on NTRU Lattice显示文摘Proxy signature plays an important role in distributed systems, mobile agent applications, distributed shared object systems, global distribution networks and mobile communications etc., since it allows the original signer to delegate another proxy signer to sign the message instead of himself. However, the proxy signature schemes constructed on the number theory cannot resist quantum computers attack and depend on the public key infrastructure. To mitigate these problems, the alternative schemes are Identity-based proxy signature constructed on lattice.In this paper, an identity-based proxy signature scheme based on Number theorem research unit(NTRU) lattice is proposed and proven secure in the random oracle. Compared with the other existing identity-based proxy signature schemes, the proposed scheme outperforms them in terms of original signer's signature size and signing key size and proxy signer's signing key size. | ZHU Hongfei TAN Yu'an YU Xiao XUE Yuan ZHANG Qikun ZHU Liehuang LI Yuanzhang | 2018 | Chinese Journal of Electronics2018，27，2： | 3 |
| 17 | A Specific-Targeting Asymmetric Group Key Agreement for Cloud Computing显示文摘When the information is exchanged and transmitted among the group members in mobile cloud environment, the group members may distribute different security domains. The information exchanged among group members may have different secret levels in this environment. When a person has some secret information, he only wants to share these information with some people who have the appropriate level of security permissions, other than all the members in the group. Aiming at these needs,we propose a flexible Asymmetric group key agreement(AGKA) protocol that information exchange and transmission are specific-targeting. The paper adopts bilinear mapping and two-way anonymous authentication technology to hide personal identity authentication information, and uses storage and computing migration technology to reduce the resource consumption of mobile terminal, and also proposes the secret key factor oriented extraction and combinations technology to achieve multi-level three-dimensional complex space security information exchange requirements and meet the lightweight computing. The analysis proves that the protocol has good safety performance and low resource consumption. | TAN Yu'an ZHENG Jiamin ZHANG Qikun ZHANG Xiaosong LI Yuanzhang ZHANG Quanxin | 2018 | Chinese Journal of Electronics2018，27，4： | 2 |
