Research on Data Protection Based on Encrypted Attribute Access Control in Cloud Computing

One of the most promising applications in cloud computing is online data sharing. How to share user data safely and efficiently has become one of the most challenging problems in cloud computing. Encryption attribute access control is a powerful guarantee against unauthorized users from accessing sensitive data in the cloud. However, it only increases the difficulty of illegal data access. It does not know whether data has illegal access in time, nor can it adopt timely optimization and adjustment of access control policies. Based on the encryption attribute access control strategy, this paper provides a data protection model, and provides a data access detection algorithm, forms a closed-loop control, provides timely feedback evidence for continuous optimization of data access control strategies, and improves data protection's integrity.
