ImgFS: a transparent cryptography for stored images using a filesystem in userspace

Osama A. KHASHAN,Abdullah M. ZIN,Elankovan A. SUNDARARAJAN

《信息与电子工程前沿（英文）》 2015年第16卷第1期页码 28-42 doi: 10.1631/FITEE.1400133

摘要： Real-time encryption and decryption of digital images stored on end-user devices is a challenging task due to the inherent features of the images. Traditional software encryption applications generally suffered from the expense of user convenience, performance efficiency, and the level of security provided. To overcome these limitations, the concept of transparent encryption has been proposed. This type of encryption mechanism can be implemented most efficiently with kernel file systems. However, this approach has some disadvantages since developing a new file system and attaching it in the kernel level requires a deep understanding of the kernel internal data structure. A filesystem in userspace (FUSE) can be used to bridge the gap. Nevertheless, current implementations of cryptographic FUSE-based file systems suffered from several weaknesses that make them less than ideal for deployment. This paper describes the design and implementation of ImgFS, a fully transparent cryptographic file system that resides on user space. ImgFS can provide a sophisticated way to access, manage, and monitor all encryption and key management operations for image files stored on the local disk without any interaction from the user. The development of ImgFS has managed to solve weaknesses that have been identified on cryptographic FUSE-based implementations. Experiments were carried out to measure the performance of ImgFS over image files’ read and write against the cryptographic service, and the results indicated that while ImgFS has managed to provide higher level of security and transparency, its performance was competitive with other established cryptographic FUSE-based schemes of high performance.

Preparation of transparent BaSO

Le Fang, Qian Sun, Yong-Hong Duan, Jing Zhai, Dan Wang, Jie-Xin Wang

《化学科学与工程前沿（英文）》 2021年第15卷第4期页码 902-912 doi: 10.1007/s11705-020-1985-y

摘要： BaSO nanoparticles as important functional materials have attracted considerable research interests, due to their X-rays barrier and absorption properties. However, most of BaSO nanoparticles prepared by traditional technology are nanopowders with broad size distribution and poor dispersibility, which may greatly limit their applications. To the best of our knowledge, the synthesis of transparent BaSO nanodispersions was rarely reported. Here, we firstly present a novel and efficient method to prepare transparent and stable BaSO nanodispersions with a relatively small particle size around 10 to 17 nm using a precipitation method in a rotating packed bed (RPB), followed by a modification treatment using stearic acid. Compared with the BaSO prepared in a traditional stirred tank, the product prepared using an RPB has much smaller particle size and narrower size distribution. More importantly, by using RPB, the reaction time can be significantly decreased from 20 min to 18 s. Furthermore, the transparent BaSO -polyvinyl butyral nanocomposite films with good X-ray shielding performance can be easily fabricated. We believe that the stable BaSO nanodispersions may have a wide range of applications for transparent composite materials and coatings with X-ray shielding performance for future research.

Model test and discrete element method simulation of shield tunneling face stability in transparent clay

Huayang LEI, Yajie ZHANG, Yao HU, Yingnan LIU

《结构与土木工程前沿（英文）》 2021年第15卷第1期页码 147-166 doi: 10.1007/s11709-020-0704-6

摘要： The stability of the shield tunneling face is an extremely important factor affecting the safety of tunnel construction. In this study, a transparent clay with properties similar to those of Tianjin clay is prepared and a new transparent clay model test apparatus is developed to overcome the “black box” problem in the traditional model test. The stability of the shield tunneling face (failure mode, influence range, support force, and surface settlement) is investigated in transparent clay under active failure. A series of transparent clay model tests is performed to investigate the active failure mode, influence range, and support force of the shield tunneling face under different burial depth conditions, whereas particle flow code three-dimensional numerical simulations are conducted to verify the failure mode of the shield tunneling face and surface settlement along the transverse section under different burial depth conditions. The results show that the engineering characteristics of transparent clay are similar to those of soft clay in Binhai, Tianjin and satisfy visibility requirements. Two types of failure modes are obtained: the overall failure mode (cover/diameter: / ≤1.0) and local failure mode ( / ≥2.0). The influence range of the transverse section is wider than that of the longitudinal section when / ≥2.0. Additionally, the normalized thresholds of the relative displacement and support force ratio are 3%–6% and 0.2–0.4, respectively. Owing to the cushioning effect of the clay layer, the surface settlement is significantly reduced as the tunnel burial depth increases.

《环境科学与工程前沿（英文）》 2020年第14卷第4期 doi: 10.1007/s11783-020-1251-z

摘要： Abstract • A novel Z-scheme Si-SnO2-TiOx with SnO2 as electron mediator is first constructed. • Transparent and conductive SnO2 can pass light through and promote charge transport. • VO from SnO2 and TiOx improve photoelectrochemical performances. • Efficient photocatalytic degradations originate from the Z scheme construction. Z-scheme photocatalysts, with strong redox ability, have a great potential for pollutants degradation. However, it is challenging to construct efficient Z-scheme photocatalysts because of their poor interfacial charge separation. Herein, by employing transparent and conductive SnO2 as electron mediator to pass light through and promote interfacial charge transportation, a novel Z-scheme photocatalyst Si-SnO2-TiOx (1

从资源共享到服务共享：透明计算的机遇与挑战

张尧学,周悦芝

《中国工程科学》 2009年第11卷第8期页码 10-17

摘要：

随着计算机和网络技术以及应用的不断快速发展，计算模式从最初的以主机计算为主，发展到以桌面(PC)计算为主，再发展到现在的以网络计算为主，乃至普适计算。然而，迄今为止的计算模式还是遵循以单机或单机联合为基础的单机思维模式，因此，目前的计算模式还是一种以“资源共享”为主要特征的计算。在网络和普适计算的新时代，用户关心的主要是服务和服务共享，计算机也将从以“资源共享”为特征的计算过渡到以“服务共享”为特征的计算。笔者提出一种适应于“服务共享”的计算模式——透明计算，并对其概念、体系结构及相关关键技术进行介绍。此外，还对透明计算的未来发展及影响进行展望。

纤维膜在机械压力下由不透明到透明的转变 Article

王超, 赵景, 刘柳, 张鹏, 王先锋, 俞建勇, 丁彬

《工程（英文）》 2022年第19卷第12期页码 84-92 doi: 10.1016/j.eng.2021.02.018

摘要：

智能可穿戴设备、电子皮肤、空气过滤和组织工程等领域，对透明薄膜材料或基材的需求很大。传统透明材料，如玻璃、塑料等，由于缺乏相互连通的孔道、不理想的孔隙率和柔性，不能满足这些新兴领域的要求。静电纺丝纤维膜因其具有小孔径、高孔隙率和良好的柔性等优点可以弥补传统材料的不足，因此，开发透明的静电纺丝纤维膜具有重大的价值。本文报道了一种简单有效的方法，在不使用任何其他添加剂的情况下，通过机械压力，直接将静电纺丝纤维膜制备成柔性的、有孔的透明纤维膜材料。同时，首次总结了压制后聚合物的透明度性能与分子结构之间的关系。经过机械压力处理后，纤维膜仍可以保持纤维形态、微米级孔道和一定的孔隙率。以聚苯乙烯静电纺丝纤维膜为例，所制备的透明聚苯乙烯纤维膜具有优异的光学性能和机械性能。透明纤维膜可实现高透光率（≈89%，可见光波长在550 nm处）、大孔隙率（10%~30%）和强的机械拉伸强度（≈148 MPa），该拉伸强度约为初始静电纺丝纤维膜的78倍。此外，本文基于透明纤维膜，利用真空辅助抽滤银纳米线和机械压力作用，制备出透明的导电纤维膜材料。与氧化铟锡导电薄膜相比，我们所制备的透明导电纤维膜展示出良好的导电性（9 Ω·sq^-1，78%的透光率）和优异的机械性能（可承受大量的弯曲应力）。

MULKASE：一种针对多个所有者数据的新型密钥聚合可搜索加密方法 Regular Papers

Mukti PADHYA, Devesh C. JINWALA

《信息与电子工程前沿（英文）》 2019年第20卷第12期页码 1717-1748 doi: 10.1631/FITEE.1800192

摘要：最新密钥聚合可搜索加密（KASE）尝试将搜索加密数据与支持数据所有者相结合，共享一个聚合的可搜索密钥；该密钥授权用户搜索数据。相应地，用户需提交一个单一聚合陷门至云端，在共享数据集上执行关键词搜索。然而，现有KASE方法不支持使用单一聚合陷门在由多个所有者共享的数据上搜索。因此，本文提出MULKASE方法，该方法允许用户使用单一陷门在由多用户拥有的不同数据记录上搜索。在MULKASE方法中，聚合密钥尺寸不依赖于数据所有者拥有的文档数量，即使外包密文数量超出预定限值，聚合密钥尺寸维持不变。安全性分析证实MULKASE方法对所选消息攻击和关键词攻击安全，亦证实该方法对交叉配对攻击安全，且提供查询隐私。理论和实验分析表明MULKASE方法性能优于现有KASE方法。文中还演示了MULKASE方法如何执行联合搜索。

《化学科学与工程前沿（英文）》 2008年第2卷第3期页码 248-252 doi: 10.1007/s11705-008-0048-6

摘要： High-quality neodymium-doped yttrium aluminum garnet (Nd:YAG) transparent ceramic (4.0 mole percent) was fabricated by a solid-state reaction method and vacuum sintering. The microstructure, optical transmittance, spectral properties and laser performance were investigated. The average grain size of the sample is about 10 ?m. The transmittance of a 2.8-mm thick sample reaches 79.5% at the laser wavelength of 1064 nm. The highest absorption peak is centered at 807 nm and the absorption coefficient is 13.9 cm. The absorption coefficient at the laser wavelength is 0.2 cm. The main emission peak is at 1064 nm and the fluorescence lifetime is 102 ?s. A laser diode (808 nm) whose maximum output is about 1000 mW was used as a pump source and an end-pumped laser experiment was performed. The 1064 nm-CW-laser output was obtained and the threshold is 733 mW. With 998 mW of maximum absorbed pump power, a laser output of 17 mW is obtained with a slope efficiency of 6.1%.

《信息与电子工程前沿（英文）》 2019年第20卷第8期页码 1049-1060 doi: 10.1631/FITEE.1700534

摘要：可搜索公钥加密使存储服务器在未知数据内容时能对其存储的加密数据进行搜索，这为加密数据存储系统检索密文提供一种非常理想的解决方法。无证书公钥密码体制是一种具有许多优点的新型密码学原语，它不仅克服了基于身份密码体制中的密钥托管问题，而且避免了传统公钥密码体制中复杂的证书管理问题。目前文献中已有3个带关键字搜索的无证书公钥加密方案。然而，这些方案的构造都需要使用耗时的双线性对运算，因此不适用于计算资源受限或电量受限的设备。针对这一问题，我们设计了一个不依赖双线性对的带关键字搜索的无证书公钥加密方案。基于计算性Diffie-Hellman问题的困难性假设，我们证明所提出方案在随机预言模型中满足适应性选择关键字攻击下的密文不可区分安全性。效率对比和仿真实验表明，该方案具有更好性能。此外，我们还给出3个拓展方案。

标准模型下基于高效分级身份的格上加密方案 Article

Feng-he WANG,Chun-xiao WANG,Zhen-hua LIU

《信息与电子工程前沿（英文）》 2016年第17卷第8期页码 781-791 doi: 10.1631/FITEE.1500219

摘要：本文在标准模型下，利用固定维数的格基代理算法提出了一种高效的格基分级身份加密方案。其公钥尺寸仅为(dm2+mn)log q比特，而消息-密文扩展因子仅为log q，其中d为最大分级深度，(n, m, q)为公开参数。本文构造了一种新的公钥赋值算法，将1个随机、公开的矩阵平均赋值为两个身份比特，从而仅仅需要d个公开矩阵来构造标准模型下的HIBE方案；与之相比，Crypto 2010所提出的HIBE方案中需要2d个同样尺寸的矩阵，公钥尺寸达到(2dm2+mn+m)log q。为了将该方案的消息-密文扩展因子压缩到log q，本文基于Gentry的加密方案建立了一种基础加密算法，一次加密操作中能够加密m2比特明文并得到m2log q比特密文。因此，文中所提方案在公钥尺寸、消息-密文扩展因子等方面具有一定的优势。基于差错学习问题的困难性，我们证明该方案在选择身份、选择明文攻击下是安全的。

Self-extinguishing and transparent epoxy resin modified by a phosphine oxide-containing bio-based derivative

Gang Tang, Ruiqing Zhao, Dan Deng, Yadong Yang, Depeng Chen, Bing Zhang, Xinliang Liu, Xiuyu Liu

《化学科学与工程前沿（英文）》 2021年第15卷第5期页码 1269-1280 doi: 10.1007/s11705-021-2042-1

摘要： A phosphine oxide-containing bio-based curing agent was synthesized by addition reaction between furan derivatives and diphenylphosphine oxide. The molecular structure of the as-prepared bio-based curing agent was confirmed by Fourier transform infrared spectroscopy and nuclear magnetic resonance spectroscopy. Dynamic mechanical analysis results indicated that with the increase of bio-based curing agent content, the glass transition temperature of epoxy/bio-based curing agent composites decreased, which was related to the steric effect of diphenylphosphine oxide species that possibly hinder the curing reaction as well as the reduction in the cross-linking density by mono-functional N H. By the addition of 7.5 wt-% bio-based curing agent, the resulting epoxy composite achieved UL-94 V-0 rating, in addition to limiting oxygen index of 32.0 vol-%. With the increase of content for the bio-based curing agent, the peak of heat release rate and total heat release of the composites gradually decreased. The bio-based curing agent promoted the carbonization of the epoxy matrix, leading to higher char yield with good thermal resistance. The high-quality char layer served as an effective barrier to retard the diffusion of decomposition volatiles and oxygen between molten polymers and the flame. This study provides a renewable strategy for fabricating flame retardant and transparent epoxy thermoset.

《信息与电子工程前沿（英文）》 2017年第18卷第3期页码 317-331 doi: 10.1631/FITEE.1500415

摘要：我们提出一种超轻量，紧凑且低功耗的分组密码：BORON。BORON是一种替换、互换网络，运行于64位纯文本上，支持128位或80位密钥长度。针对128位密钥和80位密钥，BORON的紧凑结构分别需要1939个和1626个等效门（gate equivalents, GE）。BORON包含移位、循环移位和异或操作。其的独特设计有助于在较少的回合内产生大量的活动S-box，从而挫败针对加密的线性或差分攻击。BORON在硬、软件平台上均具有较好的性能。与轻量加密LED相比，BORON具有更低的功耗水平；与现有SP网络加密相比，BORON具有更高的吞吐量。本文还展示了BORON的安全性分析及其作为超轻量紧凑型加密的性能。BORON可适用于将引脚面积和功率耗散作为关键参数的应用。

摘要：

云制造是实现智能制造的三大关键技术之一。本文提出了一种新的基于属性的计算机辅助设计（CAD）装配模型加密方法，有效地支持云制造中协同设计场景的层次访问控制、完整性验证和变形保护。设计了装配层次访问树（AHAT）作为层次访问结构。部件密文（ACT）文件中包含与属性相关的密文元素，其适用于内容密钥解密而不是CAD装配体文件。我们修改原始的默克尔树（MT）并重建装配体MT。所提出的ABE框架具有将变形保护方法与CAD模型的内容保密性相结合的能力。在标准假设下，所提出的加密方案被证明是安全的。在典型的CAD装配模型上进行的实验仿真表明，该方法在应用中是可行的。
