AN EFFICIENT AND SECURE POLICY UPDATE OUTSOURCING SCHEME FOR BIG DATA STORAGE IN CLOUD
Journal Title: Elysium Journal of Engineering Research and Management - Year 2016, Vol 3, Issue 5
Abstract
Store the big data in cloud is a best and an effective option due to its high volume and velocity. Generally, the cloud has the capability to store the big data and to process the high volume of user access requests. In cloud environment, the Attribute Based Encryption (ABE) technique ensures the end-to-end security of big data. But, the policy updating is a challenging issue, when the ABE is used to construct an access control schemes. With the help of trivial implementation, a data owners retrieve the data and reencrypt it under new access policy, then send it back to the cloud. However, this approach sustains high communication overhead and heavy computational burden. Thus, this paper proposes a novel scheme to enable an efficient access control with dynamic policy updating for storing the big data in cloud. In this paper, an outsourced policy updating method is developed for designing the ABE systems that avoids the transmission of encrypted data and reduces the computation work of data owners. To check whether the cloud server has updated the cipher-texts correctly, an efficient and secure method was also proposed in this work. Finally, the experimental analysis demonstrates that the proposed system is correct, secure, efficient and complete.
