Secure data storage and access for fish monitoring in cloud environment
No full textCloud computing (CC) refers to the on-demand availability of computer system resources, specifically data storage and computational power, without the user's direct active administration. Large cloud functions are usually split across multiple sites, each of which is a data center. Improve the security howerver, these method possess some disadvantages such as access time, resource utilization, limited computation and storage capacity. To overcome these challenges trapdoor-based NDSGA-II AC (Non-Dominated Sorting Genetic Algorithm Access Control) is proposed, In the proposed technique trapdoor has been used which reduces the energy consumption when compared to the existing systems. With the help of trapdoor access control and NDSGA-II, this paper stores water tank parameters in the cloud. A stream cipher algorithm (SCA) is utillize to encrypt the input data based on the water tank parameters collected with sensors. It is possible to store encrypted data in the cloud once the encrypting process is complete. To decrease energy consumption, average resource utilization, and access time, the trapdoor-based NDSGA-II access control is used. In this paper, Number Theory Research Unit (NTRU) cryptosystem, CP-ABE, and RBAC are used to analyze the performance of the proposed method. This proposed method reduces the encryption time by 11%, 16%, and 23% compared to the current method, and the access time by 8% and 15% compared to CP-ABE and RBAC

No full textNot AvailablePowdery mildew (PM, caused by Golovinomyces orontii) is one of the major diseases on sunflower that causes severe yield losses in the tropics. Sources of resistance to PM are reported in an exotic accession and some wild Helianthus species. The present study aims at quantitative proteomic analysis of susceptible, resistant, and immune genotypes of sunflower in response to PM infection at 3, 7, 10 days post infection. The majority of differentially expressed proteins in the resistant genotype belonged to oxidative stress (catalase, ATP-sulfurylase, and formate dehydrogenase), defense (HSP-70, heat shock transcription factors), and photosynthesis (LHCB3). In case of
immune genotype, 50% of proteins are related to photosynthesis, which play a key role in plant immunity, whereas a few similar proteins are also expressed in the susceptible genotype, but in their reduced abundance besides being inadequate in timing of expression probably leading to its susceptibility to PM. KEGG enrichment analysis shows that carbon metabolism (6-phosphogluconate dehydrogenase, pyruvate dehydrogenase, glutamine synthetase), photosynthesis, and plant–pathogen protein pathways are key pathways governing the resistance. The transcriptional expression of
eight of nine differentially expressed proteins are in agreement with the expression of proteins at the corresponding time. The present study provides information on the key proteins that are upregulated in resistant and immune genotypes which restrict the disease progression and constitutes the first quantitative proteomic data of sunflower-PM infection process.Not Availabl
