Secure Data Sharing in Cloud Computing Environment using Attribute Based Encryption

Cloud computing (CC) is a swiftly rising form of computation age. In our study we find that CC is the delivery of computing resources in the form of paid/free services based concepts which are further known as PAY-PER-USE, data processing software and meaningful data over the network It is also increasing the risk of data vulnerability. On one hand, the client or organizations store up their important data in cloud based storage server where safety measures methods used to shelter the data against discloser of privacy or misusing of data. On the other hand in all we know that in public model of cloud computing, since the user’s data is stored anywhere from corner to corner of the globe, so that the client or organizations have no control over the cloud server side. To make sure the faith on data privacy, Attribute-based encryption has been an ideal data encryption implements to unravel the exigent hitch of protected data sharing in cloud computing atmosphere. The united records files in general have the attribute of multiple levels of chains of command. Yet, in this type of file storage configuration of united files has not been investigated in ABE. For this, proficient file based ABE scheme is proposed in cloud computing.
