A NOVEL IMPLEMENTATION OF ATTRIBUTE BASED ENCRYPTION FOR QUERY OPTIMIZATION IN BIG DATA USING MAPREDUCE

Abstract

Data increased daily and has a significant role in every field, like industries, medical, etc. The data is captured, stored, and it is processed to retrieve the necessary data. Security and privacy play an essential role when critical data is shared among users in a distributed environment. These challenges are to be addressed. Mainly they are highly required during sharing and storing vast amounts of data. This paper presents a novel solution to secure the vast data with Attribute-based encryption (ABE), providing access control that prevents unauthorized user's access. Moreover, query optimization is provided in this paper to retrieve the required encrypted data from the big data quickly.
