A Novel Safe File Sharing Method Based on Cloud Storage Structure in DHT Networks
Zhongning Lu,Gaofeng Shen 보안공학연구지원센터 2015 International Journal of Security and Its Applicat Vol.9 No.7
Safe file sharing mechanism in cloud storage is one of the most significant elements that affects the development of security technology. With application of homomorphic key agreement mechanism、Shamir secret sharing algorithm. Bloom Filter and B-tree search algorithm and Rsync data updating algorithm, a safe file sharing scheme in cloud storage is established based on cloud storage infrastructure of DHT networks. Under the circumstance of cloud storage, the scheme can make full use of the sharing mechanism and achieve the confidentiality and integrity of the file. Based on DHT networks, the analysis and test of data sharing are conducted in the paper. Together with file upload and download, the test of data encryption and decryption is done on the basis of Dropbox. As the result shows, the scheme puts forward a safe and effective solution to safe file sharing in cloud storage.

Synthesis of hairpin DNA mediated Au-Ag bimetallic nanomushrooms for antibacterial application
Fu, Jingtai,Huang, Lu,Yu, Zhongning,Zhang, Zhuomin,Li, Gongke Techno-Press 2021 Advances in nano research Vol.11 No.1
Precise control of the synthesis of bimetallic nanoparticles with specific morphology and structure is of great significance due to their excellent catalytic, optical and biological property. DNA molecules are considered as a kind of efficient templates to mediate the precise synthesis of bimetallic nanoparticles with homogeneous morphology due to their specific and controllable structure. In this study specific hairpin DNA strands were successfully utilized as templates to mediate the synthesis of special mushroom-like Au-Ag bimetallic nanoparticles with a high yield of > 90%. Several key factors greatly influencing the precise control of the morphology and UV-Vis characteristics of the proposed Au-Ag nanomushrooms during synthesis were investigated and optimized in detail, including the structure of template DNA, loading amounts of DNA, types of reductant agents and surfactants. Then, the formation mechanism of hairpin DNA mediated Au-Ag nanomushrooms was studied. Finally, the proposed Au-Ag nanomushrooms with good biocompatibility were applied for the antibacterial study by the growth curve of E. coli. The proposed Au-Ag nanomushrooms showed the effective inhibition capability for the growth of E. coli. The results suggested that these DNA mediated Au-Ag nanomushrooms possessed great potential applications for biomedical science in future.
