| 1 | Chaotic Image Encryption Algorithm by Correlating Keys with Plaintext显示文摘A novel image encryption scheme based on the modified skew tent map was proposed in this paper. In the key generating procedure, the algorithm generates a plaintext-dependent secret keys set. In the encryption process, the diffusion operation with cipher output feedback is introduced. Thus, cipher-image is sensitive to both initial keys and plaintext through only one round diffusion operation. The key space is large. As a result, the algorithm can effectively resist differential attacks, statistical attacks, brute-force attacks, known plaintext and chosen plaintext attacks. Performance test and security analysis demonstrates that this algorithm is eficient and reliable, with high potential to be adopted for secure communications. | Zhu Congxu Sun Kehui | 2012 | China Communications2012，9，1： | 6 |
| 2 | A NEW METHOD FOR DEOXIDIZATION AND CHLORINATION OF REFINED ILMENITE WITH HIGH MAGNESIA AND CALCIA CONTENTS显示文摘A new process is proposed to utilize refined ilmenite with high magnesia and calcia contents, which is the main secondary resource from vanadium-bearing titaniferous magnetite in Panzhihua, covering about 40% of the worlds titanium. The refined ilmenite was first deoxidized to separate the iron in the ore in order to enrich the titanium. The mechanism of chlorination of the titanium-rich slag was analyzed using the HSC chemistry software. Following deoxida-tion, a tandem fluidized bed was applied to chlorinating the titanium-rich slag. Modeling of the tandem fluidized bed ex-plains how this serial operation can effectively improve the convention ratio of TiO2 to TiCl4. | BinLi ZhangfuYuan WenbingLi CongXu | 2004 | China Particuology2004，2，2： | 4 |
| 3 | Dynamics of a Strengthened Chaotic System and Its Circuit Implementation显示文摘To strengthen a chaotic system, a state feedback controller is applied to generate hyperchaotic behaviors based on the simplified Lorenz system, and a coordinate transformation is used for converting topological structure of the hyperchaotic system from two wings to four wings. Complex dynamics of the hyperchaotic and four-wing attractor system are analyzed and verified by Lyapunov exponent spectrums, bifurcation diagrams,phase portraits, Poincar′e sections and circuit realization.The circuit experiment results are agreed well with the simulation results, and it lays a good foundation for the chaotic secure communication. | SUN Kehui LIU Xuan ZHU Congxu | 2014 | Chinese Journal of Electronics2014，23，2： | 4 |
| 4 | Covalent Triazine Framework Nanosheets for Efficient Energy Storage and Conversion显示文摘Two-dimensional crystalline covalent triazine frameworks(CTFs)have received much attention because oftheir unique triazine structure,which endows CIFs with high thernal and chemical stability,high proportion of nitrogen and permanent porosity.Based on this unique structure characteristic.CTFs have shown great potential in energy storage and conversion due to the intrinsically strong conjugated structure.delocalized electron and rich active sites.However.charge carrier(electron,hole or ion)transport can't reach the deep active sites and charge diffusion was impeded by defects in bulk CTFs.Hence,to break through this barrier,increasing attention has been paid to get few lavered CTFs or CTFs nanosheets in order to shorten the pathways of charge diffiusion and expose more active sites.This review summarizes the synthetic methodologies of CTFs nanosheets and the potential application in photocatalvtic and electrochemical energy storage and conversion. | SUN Tian WANG Congxu XU Yuxi | 2020 | Chemical Research in Chinese Universities2020，36，4： | 2 |
| 5 | Chaos-Based Multipurpose Image Watermarking Algorithm显示文摘To achieve the goal of image content authentication and copyright protection simultaneously, this paper presents a novel image dual watermarking method based on chaotic map. Firstly, the host image was split into many nonoverlapping small blocks, and the block-wise discrete cosine transform (DCT) is computed. Secondly, the robust watermarks, shuffled by the chaotic sequences, are embedded in the DC coefficients of blocks to achieve the goal of copyright protection. The semi-fragile watermarks, generated by chaotic map, are embedded in the AC coefficients of blocks to obtain the aim of image authentication. Both of them can be extracted without the original image. Simulation results demonstrate the effectiveness of our algorithm in terms of robustness and fragility. | ZHU Congxu LIAO Xuefeng LI Zhihua | 2006 | Wuhan University Journal of Natural Sciences2006，11，6： | 2 |
