Abstract: With the rapid development of cloud computing technology, cloud-based data storage has become a common choice for both enterprises and individual users. However, data security and access control in cloud storage environments have emerged as critical challenges. This paper focuses on attribute-based encryption algorithms for access control (CP-ABE) and proposes an improved CP-ABE model tailored for cloud storage access control needs. This model employs flexible attribute policies to achieve precise control over data access in the cloud, enhancing both security and privacy. The paper begins by introducing the basic principles and improvements of the CP-ABE algorithm, followed by the design and implementation of a data access control system. A detailed analysis of the system's performance and security is provided. Experimental results indicate that the proposed model demonstrates significant advantages in terms of efficiency and security in data access control. This research provides a potentially effective technical approach for secure data access in cloud storage environments.
