A Design of Sharing Algorithm Based on Attribute–Based Encryption in Cloud Storage Environment

With the development of cloud computing, more and more users store their data in the cloud, the use of traditional plaintext storage of data is not suitable for the open cloud storage environment, and the symmetric encryption-based scheme is not suitable for the sharing of data and collaborative work in the cloud. In view of the diversified needs of users for secure data sharing in cloud storage, the corresponding rule management mechanism is introduced, the improved Attribute-Based Encryption algorithm is designed to improve the efficiency of attribute revocation, and the sharing model has better security through the corresponding analysis. Finally, the cpabe related toolset is used for testing, and the results show that the method has better performance.
