FAC-MACS: Fortified Access Control for Multi-Authority Cloud Storage Using CPABE

Security and data privacy is paramount to cloud users seeking to protect their gigabytes of vibrant business data from the inquisitive eyes of unauthorized users who are attempting to exceed their authority and also it becomes a challenging issue in cloud storage systems. Ciphertext-Policy Attribute-based Encryption (CP-ABE) is observed as one of the most seemly technologies for data access control in cloud storage, because it gives more direct control access strategies to the cloud data owners. This CP-ABE scheme provides intrinsic security mechanisms designed to minimize the security attacks and threats in cloud system. In this paper, we design a Fortified Access control for Multi-Authority Cloud Storage Systems, where the process of data access control is strengthened to ensure the safety of the cloud data. Fortified access control to discourse not only the data privacy difficulties in existing control scheme, by using multiple authorities in the cloud storage system, the proposed scheme can efficiently reaches the tenable access control and revokes the anonymous access to the cloud data. The study and simulation analysis illustrates that proposed well organized Fortified Access Control is both secure and efficient for Cloud Storage Systems.
