Abstract:

Data read control is an effective way to ensure the data self-assurance in the cloud. Due to data farm out and untrusted cloud servers, the data read control becomes a challenging broadcast in cloud loading systems. Ciphertext-Policy Attributebased Encryption (CP-ABE) is regarded as one of the most suitable technologies for data read control in cloud loading, because it gives data owners more direct control on read rules. However, it is hard to directly apply existing CP-ABE system to data access control for cloud loading systems because of the elements overturning problem., we design anexpressive,efficient and revocable data access control system for multi-authority cloud storage systems, where there are multiple authorities co-exist and each authority is able to broadcast elements independently. Specifically, we suggest a revocable multi-authority CP-ABE system, and apply it as the underlying techniques to design the data access control scheme. Our elements overturning method can efficiently achieve both forward security and backward security. The analysis and simulation results show that our suggest data access control scheme is secure in the random oracle model and is more efficient than previous works.
