Research On Cloud Data Storage Protection Technology

At present,the research in the field of cloud data technology is changing with each passing day.In the cloud environment,users can store and manage the data information resources needed by IT sharing data resources,so that the data can be greatly improved in resource utilization efficiency.Cloud data privacy security has brought a very big threat and challenge.In the current environment,the key point of cloud computing security lies in the protection of cloud data storage technology,the need to find a reliable and secure way to ensure the security of cloud data,so as to provide a stable basis for cloud computing.This paper chooses the cloud data storage protection technology to study the data encryption technology,and try to design a more secure and efficient cloud data storage scheme.The main results of this paper include the following three points:This paper analyzes the advantages and disadvantages of various data security protection mechanisms by studying the advantages and disadvantages of cloud computing,cloud storage at home and abroad,the main technology of current data storage in privacy protection,the advantages and disadvantages of Hadoop platform technology.In this paper,the cloud data storage user data sensitivity as the starting point,by cloud data according to different sensitivity is divided into different levels,to build a cloud storage environment cloud data sensitivity model framework,developed a cloud Data storage security protection scheme,which uses different encryption protection schemes according to the difference of stored data sensitivity to realize the security performance of data storage in cloud environment.Based on the existing data encryption algorithm,this paper proposes a scheme of combining symmetric encryption algorithm with asymmetric encryption algorithm:AES-RSA algorithm and AES-ECC algorithm to realize the effective protection of cloud data.The scheme solves the traditional symmetry Encryption algorithm program in the key is not easy to manage,poor security and other defects,and in the encryption of the performance can be significantly improved and improved.In this paper,the algorithm of symmetric encryption algorithm and asymmetric encryption algorithm proposed by traditional encryption algorithm(DES,RSA,ECC,AES)is compared with that of Hadoop Eclipse.The new algorithm proposed by symmetric encryption and symmetric encryption algorithm proposed in this paper has obvious advantages in safety performance and efficiency.In order to optimize the security of cloud data storage privacy,this paper designs three algorithms,such as data segmentation algorithm,identifier generation algorithm and data hiding algorithm,to analyze the feasibility of privacy protection scheme by setting up Hadoop platform.The experimental data table Block algorithm,data hiding algorithm to optimize the security performance of cloud data storage,while the encryption algorithm in the implementation of efficiency have a certain increase,with a certain degree of advantage.Based on the cloud data storage encryption protection technology scheme designed in this paper,the security and efficiency of cloud data storage are improved.However,it is still limited to the experimental environment,and the research needs to be deepened,and the simulation simulation degree of the cloud computing environment needs to be improved.It is necessary to further expand the experimental research on the fusion of algorithms to optimize and perfect the cloud data storage protection scheme.
