Data Encryption using SCT and access control using TRBAC in Cloud Computing for Big Data

Cloud Computing is the emerging trend to process different types of data and provide different services, and Big data is thehuge source of such data. In this paper we proposed a framework in which we encrypt data with clock timing and then provideaccess according to task and role of the user. By this we can achieve a full secured and authorized access to cloud user withsecure big data user
