A Multi-level Access Control Scheme Based on Attribute Encryption for Big Data

In order to meet the needs of flexibility and security in big data access, this paper first processes the access objects from folders, files and metadata respectively. Then, aiming at the security and efficiency problems in attribute encryption, this paper uses the processing strategy of public key encryption and private key decryption, and gives the attribute revocation. Finally, the experimental results show that the proposed scheme is feasible and effective.
