An efficient security architecture for secure authentication and data sharing in cloud enabled big data environment

Abstract

Big data refers to the large, diverse sets of information that grow at ever-increasing newlinerates. Cloud architectures satisfy the requirements very well and have been found newlineinevitable for Big Data storage and analysis. With the rapid growth of data sources, newlineimprove big data security in cloud is a challenging issue. Different issues are involved newlinein Big Data security such as infrastructure security, data privacy, data management newlineand integrity. Currently, cloud computing is considered for big data processing, newlineanalytics and storage using cryptography algorithms. But this is not enough for big newlinedata protection over cloud. In this thesis we present a big picture of addressing the newlinemain issues in big data security over cloud. We propose novel system architecture newlinecalled Secure Authentication and Data Sharing in Cloud enabled Big Data newlineEnvironment (SADS-Cloud). Three processes are involving in this process including newlineBig Data Outsourcing, Big Data Sharing and Big Data Management. newline
