| 1 | Fault diagnosis for distillation process based on CNN–DAE显示文摘Distillation is the most widely used operation for liquid mixture separation in the chemical industry. It is of great importance to detect and diagnose faults in distillation process. Due to the strong feedback and coupling of processes in a distillation column, it is difficult to use deep auto-encoders(DAEs) alone to achieve good results in detecting and diagnosing faults, in terms of accuracy and efficiency. This paper proposes a hybrid fault-diagnosis model based on convolutional neural networks(CNNs) and DAEs, by integrating the powerful capability of CNN in feature extraction and of DAE in classification. A case study was carried out with the distillation process of depropanization. It is shown that the proposed hybrid model is of good performance compared to other models, in terms of the accuracy of fault detection in such a process. Also, with the increase of structural layers of the CNN–DAE model, the diagnostic accuracy will be improved, with an optimal accuracy of 92.2%. | Chuankun Li Dongfeng Zhao Shanjun Mu Weihua Zhang Ning Shi Lening Li | 2019 | Chinese Journal of Chemical Engineering2019，27，3： | 12 |
| 2 | An Identity-Based Group Key Agreement Protocol for Low-Power Mobile Devices显示文摘In wireless mobile networks,group members join and leave the group frequently,a dynamic group key agreement protocol is required to provide a group of users with a shared secret key to achieve cryptographic goal.Most of previous group key agreement protocols for wireless mobile networks are static and employ traditional PKI.This paper presents an ID-based dynamic authenticated group key agreement protocol for wireless mobile networks.In Setup and Join algorithms,the protocol requires two rounds and each low-power node transmits constant size of messages.Furthermore,in Leave algorithm,only one round is required and none of low-power nodes is required to transmit any message,which improves the efficiency of the entire protocol.The protocol's AKE-security with forward secrecy is proved under Decisional bilinear inverse Diffie-Hellman(DBIDH) assumption.It is additionally proved to be contributory. | TENG Jikai WU Chuankun | 2016 | Chinese Journal of Electronics2016，25，4： | 11 |
| 3 | An ID-based authenticated dynamic group key agreement with optimal round显示文摘Group key agreement protocols are crucial for achieving secure group communications.They are designed to provide a set of users with a shared secret key to achieve cryptographic goal over a public network.When group membership changes,the session key should be refreshed efficiently and securely.Most previous group key agreement protocols need at least two rounds to establish or refresh session keys.In this paper,a dynamic authenticated group key agreement(DAGKA) protocol based on identity-based cryptography is presented.By making use of the members' values stored in previous sessions,our Join and Leave algorithms reduce the computation and communication costs of members.In the proposed protocol,Setup and Join algorithms need one round.The session key can be refreshed without message exchange among remaining users in Leave algorithm,which makes the protocol more practical.Its security is proved under decisional bilinear Diffie-Hellman(DBDH) assumption in random oracle model. | TENG JiKai WU ChuanKun TANG ChunMing | 2012 | Science China(Information Sciences)2012，55，11： | 7 |

| 5 | Research progress on ecological protection technology of highway slope: status and challenges显示文摘Slope protection has always been a major concern in highway construction and later operation.Ecological protection technology is widely used in highway slope,which takes into account functions of protection,ecology,and landscape.Ecological protection technology is mainly to improve the stability of the slope through the combination of supporting structure and plants,and vegetation restoration can reduce the negative impact of highway construction.In this paper,the latest research progress of ecological protection technology was first reviewed to identify the main construction process and types,which revealed the protection mechanism of ecological protection technology.The comprehensive benefits of ecological slope protection technology were analysed from the aspects of air,water circulation,landscape and biodiversity.It has found that ecological protection technology of highway slope mainly forms the atmosphere-plant-soil system.Ecological protection technology of highway slope improved the stability of the slope through the supporting structure and the anchoring effect of plant roots.And the restoration of the surface vegetation on the slope promoted the photosynthesis and transpiration of plants and purifies the air quality along the highway.Ecological protection technology of highway slope could quickly restore the ecological balance,overall landscape and biodiversity of the region. | Hongyuan Fu Huanyi Zha Ling Zeng Caiying Chen Chuankun Jia Hanbing Bian | 2020 | Transportation Safety and Environment2020，2，1： | 6 |
| 6 | Construction and enumeration of Boolean functions with maximum algebraic immunity显示文摘Algebraic immunity is a new cryptographic criterion proposed against algebraic attacks. In order to resist algebraic attacks, Boolean functions used in many stream ciphers should possess high algebraic immunity. This paper presents two main results to find balanced Boolean functions with maximum algebraic immunity. Through swapping the values of two bits, and then generalizing the result to swap some pairs of bits of the symmetric Boolean function constructed by Dalai, a new class of Boolean functions with maximum algebraic immunity are constructed. Enumeration of such functions is also given. For a given function p(x) with deg(p(x)) < n2 , we give a method to construct functions in the form p(x)+q(x) which achieve the maximum algebraic immunity, where every term with nonzero coefficient in the ANF of q(x) has degree no less than n2 . | ZHANG WenYing WU ChuanKun LIU XiangZhong | 2009 | Science in China(Series F)2009，52，1： | 4 |
| 7 | Large scale preparation of 20 cm×20 cm graphene modified carbon felt for high performance vanadium redox flow battery显示文摘Vanadium redox flow batteries(VRFBs)are widely applied in energy storage systems(e.g.,wind energy,solar energy),while the poor activity of commonly used carbon-based electrode limits their large-scale application.In this study,the graphene modified carbon felt(G/CF)with a large area of 20 cm×20 cm has been successfully prepared by a chemical vapor deposition(CVD)strategy,achieving outstanding electrocatalytic redox reversibility of the VRFBs.The decorating graphene can provide abundant active sites for the vanadium redox reactions.Compared with the pristine carbon felt(CF)electrode,the G/CF composite electrode possesses more defective sites on surface,which enhances activity toward VO^(2+)/VO^(2+)couple and electrochemical performances.For instance,such G/CF electrode delivered remarkable voltage efficiency(VE)of 88.4%and energy efficiency(EE)of 86.4%at 100 mA·cm^(-2),much higher than CF electrode by 2.1%and 3.78%,respectively.The long-term cycling stability of G/CF electrode was further investigated and a high retention value of 47.6%can be achieved over 600 cycles.It is demonstrated that this work develops a promising and effective strategy to synthesize the large size of carbon electrode with high performances for the next-generation VRFBs. | Ting Long Yong Long Mei Ding Zhizhao Xu Jian Xu Yiqiong Zhang Mingliang Bai Qijun Sun Gen Chen Chuankun Jia | 2021 | Nano Research2021，14，10： | 3 |

| 9 | Identification of abnormal conditions in high-dimensional chemical process based on feature selection and deep learning显示文摘Identification of abnormal conditions is essential in the chemical process.With the rapid development of artificial intelligence technology,deep learning has attracted a lot of attention as a promising fault identification method in chemical process recently.In the high-dimensional data identification using deep neural networks,problems such as insufficient data and missing data,measurement noise,redundant variables,and high coupling of data are often encountered.To tackle these problems,a feature based deep belief networks(DBN)method is proposed in this paper.First,a generative adversarial network(GAN)is used to reconstruct the random and non-random missing data of chemical process.Second,the feature variables are selected by Spearman’s rank correlation coefficient(SRCC)from high-dimensional data to eliminate the noise and redundant variables and,as a consequence,compress data dimension of chemical process.Finally,the feature filtered data is deeply abstracted,learned and tuned by DBN for multi-case fault identification.The application in the Tennessee Eastman(TE)process demonstrates the fast convergence and high accuracy of this proposal in identifying abnormal conditions for chemical process,compared with the traditional fault identification algorithms. | Wende Tian Zijian Liu Lening Li Shifa Zhang Chuankun Li | 2020 | Chinese Journal of Chemical Engineering2020，28，7： | 3 |

| 11 | Dynamic tree-based authenticated group key exchange protocol显示文摘Authenticated group key exchange protocols allow a group of users over a public network to establish a shared secret key for the subsequent cryptographic goals. In this paper, we extend BD-II scheme into a dynamic setting, and propose a tree-based authenticated key exchange protocol which is more suitable for dynamic groups in such as ad hoc networks. Our protocol is proven secure in random-oracle model. Additionally, we analyze the costs of our protocols in both communication and computation terms, and compare its performance with three well-known protocols. | LI Hui WU ChuanKun TENG JiKai | 2010 | Science China(Information Sciences)2010，53，8： | 2 |
| 12 | A strongly secure identity-based authenticated group key exchange protocol显示文摘In group key exchange(GKE) protocols, a shared secret key is established among a group of members for cryptographic use over a public network. An identity-based protocol is preferred to that under the employment of traditional public key infrastructure(PKI), since identity-based cryptosystem can simplify public key management procedure. In ASIACCS 2011, a security model for GKE protocol called EGBG model was proposed. The EGBG model takes ephemeral secret key leakage attack into consideration. Until now, there is no ID-based GKE protocol secure in the EGBG model. In this paper, we propose an identity-based GKE protocol. Its AKE-security with KCIR and full forward secrecy, MA-security with KCIR and its contributiveness are proven in the EGBG model. The proposed protocol does not involve NAXOS trick, which does not resist side channel attack and thus it provides stronger security guarantee. It achieves mutual authentication without applying signature, which makes the protocol more practical. | TENG JiKai WU ChuanKun TANG ChunMing TIAN YouLiang | 2015 | Science China(Information Sciences)2015，58，9： | 2 |
| 13 | CMQV+:An authenticated key exchange protocol from CMQV显示文摘Ustaoglu presents a secure and efficient key exchange protocol named CMQV,based on the design rationales of HMQV and NAXOS.Compared with the latter two protocols,on one hand,CMQV achieves high performance of HMQV,and on the other,it is proven secure in eCK model as NAXOS is.However,CMQV enjoys the security proof under gap Diffie-Hellman assumption as indicated by its creators.In this paper,we propose a variant of CMQV,called CMQV+,which is proven secure under a weaker assumption (i.e.computational Diffie-Hellman assumption) in eCK model with random oracles while maintaining the high-performance feature of CMQV as much as possible. | LI Hui WU ChuanKun | 2012 | Science China(Information Sciences)2012，55，7： | 2 |
| 14 | Estimating interaction between surface water and groundwater in a permafrost region of the northern Tibetan Plateau using heat tracing method显示文摘Understanding the interaction between groundwater and surface water in permafrost regions is essential to study flood frequencies and river water quality, especially in the high latitude/altitude basins. The application of heat tracing method,based on oscillating streambed temperature signals, is a promising geophysical method for identifying and quantifying the interaction between groundwater and surface water. Analytical analysis based on a one-dimensional convective-conductive heat transport equation combined with the fiber-optic distributed temperature sensing method was applied on a streambed of a mountainous permafrost region in the Yeniugou Basin, located in the upper Heihe River on the northern Tibetan Plateau. The results indicated that low connectivity existed between the stream and groundwater in permafrost regions.The interaction between surface water and groundwater increased with the thawing of the active layer. This study demonstrates that the heat tracing method can be applied to study surface water-groundwater interaction over temporal and spatial scales in permafrost regions. | TanGuang Gao Jie Liu TingJun Zhang ShiChang Kang ChuanKun Liu ShuFa Wang Mika Sillanpaa YuLan Zhang | 2020 | Research in Cold and Arid Regions2020，12，2： | 1 |
