Cloud storage security realization method based on data encryption and access control

Abstract

The invention provides a cloud storage security realization method based on data encryption and access control. The method comprises the following steps: when a user issuing a data persistence request to a cloud service system, the service system transmitting the data persistence request to a cloud storage platform, a data encryption software model performing encryption processing on data, and finishing data storage; when the user issues a data access request to the cloud service system, the service system transmitting the data access request to the cloud storage platform, a data access control software module performing access control on access data to determine whether to the data access request is allowed, and if the data access request is allowed, allowing access to the data after encryption; and if the access is allowed, ending the access so as to ensure the security of the data stored by the user in the cloud storage platform in a distributed mode. According to the invention, the encryption processing and the access control are performed on the data so that the data between systems of a cloud platform rejects mutual access, and thus the data security is guaranteed.

Description

technical field [0001] The invention relates to the field of cloud computing applications, in particular to a method for implementing cloud storage security based on data encryption and access control. Background technique [0002] In recent years, with the continuous improvement of the level of science and technology, cloud computing has also achieved a great degree of development, and it shows a trend of continuous progress. As a relatively new computer technology in today's society, cloud computing has the problem of data security storage. It has not been fully studied and solved. As far as the current research status of cloud computing data storage security is concerned, most of its research focuses on data protection, virtual security technology, attribute-based encryption algorithms, access control, etc., among which the most The core part is the problem of data security storage.

Problems solved by technology

[0003] The key feature of cloud computing is that its services are mainly realized through the network environment. All the information and data of network users need to be placed in the cloud, and then the results are sent back to the client in the network through calculation. Cloud computing as a A new type of service model will naturally face great security threats. Because cloud computing is distributed, in order to improve the efficiency of network resource usage, users may share storage resources or computing resources. If users The lack of effective security isolation between them or the use of attack technology by users will cause data security issues. Therefore, the stand-alone mode has different characteristics from ensuring the security of cloud data storage. It is difficult to ensure the security of the entire data using traditional data protection methods. Safety
