Expressive, Efficient, and Revocable Data Access Control for Multi-Authority Cloud Storage
|Name||Expressive, Efficient, and Revocable Data Access Control for Multi-Authority Cloud Storage|
data access control is the better way for the data security.But the challenging issue with the cloud storage comes. Ciphertext-Policy Attribute-based Encryption (CP-ABE) is regarded as one of the most suitable technologies for data access control in cloud storage, because it gives data owners more direct control on access policies. We can't apply CP-ABE scheme directly to cloud. Here we provide a revocable multi-authority CP-ABE scheme, and apply it as the underlying techniques to design the data access control scheme. Our attribute revocation method can efficiently achieve both forward security and backward security. The analysis and simulation results show that our proposed data access control scheme is secure in the random oracle model and is more efficient than previous works.
