Abstract:

With the development of big data technology, cloud storage has received more and more attention. While it brings a lot of convenience to users, it also creates new security challenges. Since users lose direct control over data after storing data on the cloud, how to safely and effectively detect the integrity of data stored on the cloud becomes an important security challenge. The technology of PDP has been a research hot spot in recent years, which can realize the integrity detection of cloud data without downloading all the data. However, most existing PDP schemes either have complex certificate management issues or have key escrow issues. In addition, these schemes do not consider the issue of control over data uploads. In view of the above problems, we propose a scheme of certificateless provable data possession with data uploading control. It first uses the technology of rights management and secret sharing to realize the control of the data uploading process, that is, only over threshold users can upload the data to the cloud, which avoids the user’s randomly uploading behavior. Secondly, the certificateless cryptographic technology is utilized, which avoids the key escrow problem and simplifies the operation of certificate management. At the same time, the security and performance of the solution are also analyzed.
