Security Solutions Of Dual-channel Cloud Data Storage

At present, technologies, solutions, specific framework for all aspects of emerging ITarchitecture improved leap to the world came gradually, cloud computing is steady developedby multifaceted impacts of the technology and business model. Today cloud computing-basedtechnology has basically been mature, and because of its strong performance and relativelylow cost, it has aroused extensive attention of quite a number of industry and even non-ITusers in the field. It also has been put into use in some areas and the corresponding revenue.At the same time, the new service model brings new problems and challenges. Such as largeconcentrations of data, high degree of sharing of network storage resources and storagemanagement rights have changed hands, all above factors makes the owner of data doubts andfears of the safety performance in the new mode. So, the data security of cloud computing hasbecome the most concerned about the problems of the world today the IT field, and the nextstep in the development and promotion of cloud computing is also directly influenced bysecurity issues and constraints. On this basis, many well-known domestic and foreign ITenterprises and cloud vendors put a lot of energy and capital into the field of data security inthe cloud computing for research and exploration, hoping to find a better solution or strategyto improve the overall security of the cloud platform properties.On the issue of security for cloud computing data storage technology is still not makinguser satisfaction, this paper intends to do to study and suggestions for improvement andinnovation on this basis to existing mainstream cloud storage solutions. Classic cloudcomputing architecture foundation would like to make a dual storage the cloud datatransmission and storage encryption improvement cloud computing model, in order toimprove the overall safety performance of cloud data. First of all, through the analysis of theexisting cloud computing data storage security solutions, this paper discusses the existing datasecurity means in the existing environment, and show the safety problem which has beenconcerned about; second, research control and storage of data in cloud computing, taken intoaccount for the data exists in the area of security risks and design prevention strategies; finally,give full consideration to play the advantages of the cloud computing model, then, on thisbasis, combined with encryption to design a new cloud security solutions, proposed adual-channel parallel storage method. Because of its the encrypted environment requirementsof low-risk and reliable safety performance has been widely recognized and applied in thefield of data security, the asymmetric encryption algorithm for data security areas for a longtime. Meanwhile, cloud computing brings technology innovation and performanceimprovement can be asymmetric encryption algorithm in the traditional IT environmentinadequacies brought to supplement and improve. Therefore, the improved dual-channel cloud data storage security solutions improved from two aspects：data parallelism and mutualasymmetric encryption, thus achieving enhance data cloud platform storage protection, userauthentication, platform disaster recovery capability.
