Design and Implementation of a Distributed Encryption System for the Cloud

Abstract

?Big Data ?- voluminous and variety of data from different sources. The Data can be either in the form of structure (or) unstructured Data. Privacy and security of Big Data is gaining high importance, since all the technologies are started to depend on Big Data. It is difficult to work with using most relational database management systems, desktop statistics and visualization packages since it requires massive parallel software running on tens, hundreds or even thousands of servers. In this paper, we are going to discuss the Hadoop and the method for maintaining the privacy & security of big Data. Originally Hadoop was invented without any security model. The main goal is to propose a Hadoop system that maintains privacy and security at the client system. Advanced Encryption Standard (AES) enables protection to data at each cluster, it performs encryption/decryption before read/write respectively and we are using SHA 1 for user authorization.
