A Novel Triple Encryption Scheme for Hadoop-Based Cloud Data Security

Cloud computing has been flourishing in past years because of its ability to provide users with on-demand, flexible, reliable, and low-cost services. With more and more cloud applications being available, data security protection becomes an important issue to the cloud. In order to ensure data security in cloud data storage, a novel triple encryption scheme is proposed in this paper, which combines HDFS files encryption using DEA and the data key encryption with RSA, and then encrypts the user's RSA private key using IDEA. We implement the triple encryption scheme in Hadoop-based cloud data storage and experiment studies were conducted to verify its effectiveness.
