Bi-directional and concurrent proof of ownership for stronger storage services with de-duplication

引用

Science China(Information Sciences) 2018年第3期61卷 84-94页

作者： Taek-young youn Ku-young CHANG Electronics and Telecommunications Research Institute

In storage service, data de-duplication is a specialized technique for eliminating duplicate copies of repeating data in storage. Especially, client-side de-duplication has more merits than server-side deduplication since they can improve both the space efficiency and the communication bandwidth. For secure client-side de-duplication, we need a way to prove the ownership of a file to be stored. In the upload step,the server should verify the ownership of a client to give the right of the file without uploading it. On the contrary, the client also want to verify the retrievability for the file since he will delete it from his storage after protocol execution. Existing proof of ownership techniques have been designed for server's need. In this paper, we first point out that we need the second property in client's view point, and give a very simple and practical solution which can support the server and the client to prove that they have the same file. We first describe a generic strategy which can help us to construction a bi-directional and concurrent proof of ownership technique from an ordinary proof of ownership technique, and then give an efficient hash-based scheme with security proof in the random oracle model.

Development of genome engineering technologies in cattle: from random to specific

Journal of Animal Science and Biotechnology 2018年第2期9卷 285-293页

The production of transgenic farm animals(e.g., cattle) via genome engineering for the gain or loss of gene functions is an important undertaking. In the initial stages of genome engineering, DNA micro-injection into one-cell stage embryos(zygotes) followed by embryo transfer into a recipient was performed because of the ease of the ***, as this approach resulted in severe mosaicism and has a low efficiency, it is not typically employed in the cattle as priority, unlike in mice. To overcome the above issue with micro-injection in cattle, somatic cell nuclear transfer(SCNT) was introduced and successfully used to produce cloned livestock. The application of SCNT for the production of transgenic livestock represents a significant advancement, but its development speed is relatively slow because of abnormal reprogramming and low gene targeting efficiency. Recent genome editing technologies(e.g.,ZFN, TALEN, and CRISPR-Cas9) have been rapidly adapted for applications in cattle and great results have been achieved in several fields such as disease models and bioreactors. In the future, genome engineering technologies wil accelerate our understanding of genetic traits in bovine and wil be readily adapted for bio-medical applications in cattle.

Mg Alloy Foam Fabrication via Melt Foaming Method

引用

Journal of Materials Science & Technology 2008年第3期24卷 302-304页

作者： Changhwan SEO bo-young HUR i-Cube Center ERISchool of Nano & Advanced Materials EngineeringGyeongsang National University

For the first time AZ91 （MgAl9Zn1） and AM60 （MgAl6） Mg alloy foams with homogeneous pore structures were prepared successfully via melt foaming method using CaCO3 as blowing agent. It is revealed that the blowing gas to foam the melt is not CO2 but CO, which comes from liquid-solid reaction between Mg melt. The reaction temperature is more than 100℃ lower than CaCO3 decomposition, which makes Mg alloy melts foam into cellular structure much more easily in the temperature range from 690℃ to 750℃.

Dendrite Spacing Selection during Directional Solidification of Pivalic Acid-Ethanol System

引用

Journal of Materials Science & Technology 2008年第3期24卷 340-342页

作者： Myung-Jin Suk young-Min Park youn-Che Kim Department of Materials and-Metallurgical Engineering Kangwon National University

Unidirectional solidification of pivalic acid （PVA）-ethanol （Eth） mixture was performed to examine whether an allowable range of primary dendrite spacing definitely exists at a given growth velocity and how the range is history-dependent. PVA-0.59 wt pct Eth was unidirectionally solidified in the range of growth velocity 0.5-64 μm/s at the temperature gradient of 2.3 K/ram. Sequential change in growth velocity was imposed to determine the upper and lower limits for the allowable range of stable spacing. An allowable range of the steady state primary spacing was observed at a given growth velocity, and the extent of the range seems to be dependent on the degree to which step-increase or step-decrease in growth velocity is accomplished. As the degree of sequential change in growth velocity increases, the history-dependence of the selection for the primary dendrite spacing tends to disappear.
