Research And Implementation Of Cloud Storage Systems Based On Optical Disk Library

Cloud computing opens up new IT innovation, creates a new work mode, being more and moreenterprise applications. Growing surge in the amount of data, hardware product procurement users tostore data more and more, this leads to a waste of a lot of hardware resources. Calculate the derivativeof the new service cloud storage as a cloud, has a low-cost, avoid the waste of resources, efficiency,scalability, favored by many users anytime, anywhere access to data, and other advantages, but thedata is transmitted over the network is stored in various storage nodes, and can’t guarantee thesecurity of transmission, how to safely save data is now the major research focus and researchinstitutions.This paper first introduces the data stored in the course of development, focusing on cloudstorage concepts and techniques to analyze the security issues of cloud storage applications, and solvethe problem, some of the key technical and security solutions. For the security of the data in thenetwork transmission of data dispersion, dispersed the user’s data stored in each storage node andseveral data dispersion method, by comparing the low-density erasure codes (LDPC) introduced to thecloud storage system, and by the experimental procedures of the LDPC code in the data separation,the performance analysis of data recovery and data security, security while protection of the datatransfer process is to improve the efficiency of the data in the encoding process.On this basis, the design of the security architecture of cloud storage system, including accesslayer, the application interface layer, infrastructure management and storage layer. Cloud storageaccess layer window, by design and friendly interface allows users to easily use cloud storage services;different interface application interface layer is developed according to the needs of users, includingfile service interface, the connection interface, storage device management interface and databaseinterface; basis of management is a core part of the cloud storage system design, the management andprotection of files on the file in the security of the transmission process in this layer design; storagelayer is designed according to the choice of storage devices equipment management processes. Thefinal realization of cloud storage system platform has the above security architecture using existingresources, through the test to verify the feasibility of data security and system function during storage.
