Research on Data Security Technology in Cloud Computing Environment
Gang Lei, Jianchen Chen, Luo Fu · 2023
With the widespread use of cloud computing, big data, blockchain and artificial intelligence, data security and privacy protection has become an important research topic in the cloud computing environment. In this paper, we propose a proof-of-data-possession (PDP) model based on blockchain and trusted third-party auditing, which aims to address the confidentiality, integrity and availability of data in the cloud environment. By combining blockchain and trusted third-party auditing technologies, the model achieves effective protection of data integrity and confidentiality, while leveraging the decentralized nature of blockchain to enable open and transparent verification of data holdings. In addition, experimental results show that the model has significant advantages over the traditional PDP model in terms of data security, data availability, and data integrity. Overall, this study provides a new solution for data security in cloud environments, which has theoretical and practical implications for both cloud service providers and users.
