Highly Secure Method based on Ciphertext Policy Attribute based Encryption in Hadoop System

Abstract

Cloud computing is one of today's most exciting technologies due to its ability to reduce costs associated with computing while increasing flexibility and scalability for computer processes. Cloud computing is set of resources and services offered through the Internet. The rapid growth in field of "cloud computing" also increases severe security concerns. Lack of security is the only hurdle in wide adoption of cloud computing. Distribution and sharing of File is one of the most critical service of cloud computing. This paper examines security for "big data" environments, reviewing built-in protections and weaknesses of these systems. In this paper, we use the Hadoop based file system and secure it using a highly secure algorithm based on ciphertext policy attributes based encryption with pairing (CP-ABE-WP with pairing). The solution aims at providing optimal performance in cloud environment and also ensures security by using a session based approach. The proposed method has maintained a hierarchy of users to ensure that files are used by their appropriate users.
