Cloud Security: Data Security and Privacy Protection for Cloud Storages

Abstract

The new development trends including the Internet of Things (IoT), smart cities, enterprise's digital transformation the world’s digital economy is at the top of the tide. The continuous growth of data storage pressure drives the fast development of the entire storage market on account of huge data generated. By providing data storage and conduct, cloud storage system becomes an important part of the new period. Such a large amount of data can create great wealth. There are some studies on data security and privacy protection, there is still a lack of regular surveys on the subject in a cloud storage system. we first make an overview of cloud storage, including definition, classification, architecture, applications. Secondly, we give a detailed research of the requirements of data security and privacy protection in cloud storage systems. Thirdly, data encryption technologies and protection methods are summarized. Finally, we talk about open research topics of data security for cloudstorage.
