A secure data access control method using AES for P2P storage cloud

P2P cloud storage is usually a combination of both cloud computing and peer-to-peer computing mechanism, where it can offer and provide huge computing, storage services and at the same time it lowers the economic cost of the real time users. Generally, cloud server and cloud users lye outside the data owners trusted domain. The P2P cloud storage creates new challenges regarding the access control and the data security while the data owner usually stores the sensitive information for sharing them in the trusted domain of cloud storage. However there are no such mechanisms available for access control in P2P storage cloud. Hence we propose a system which produces double encryption namely ABE and PRE based on the user attributes, which provides an efficient, secure and fine-grained data access control for the P2P storage cloud. The performance mechanism shows highly efficient and practical for day to day life and also it reduces computation overheads during user revocation than the other schemes.
