Multi-Authority Attribute-based Encrypted Access Control System in Cloud Storage

Computer Engineering

There Indecent times Data access control has become a Challenging issue for cloud storage systems. There are some techniques that have been applied to achieve in Semi Trusted cloud storage system for achieving the secure data access control.Cloud storage is a very important part of cloud computing which provides services to the owners of the cloud to have their data on the cloud. Cloud Computing is a way without investing in new infrastructure to dynamically increase the capacity and add features.It increases the capabilities of IT services.Cloud Computing has grown in recent years from a promising idea to an integral part of the IT industry. K.Yang et al recently proposed a basic data plan access control system (DAC-MACS) and comprehensive data access control scheme (EDAC-MACS). In what they see demanded that DAC MACS be implemented as soon as possible withdrawal and deletion of active translation. While EDAC MACS and may receive these results even if not revoked users disclose their withdrawals users. in this paper in two processes we give two attacks. During the first attack the retrieved user can listen and get other users key update keys to update. Back that as a non-return user can find you right that as a non revoked user it can obtain proper There Indecent times Data access control has become a Challenging issue for cloud storage systems.
