Improved technique for data confidentiality in cloud environment

Abstract

Cloud Computing allows anyone to provision virtual hardware, runtime environment and services. Resources can be accessed over the Internet and offered on pay-per-use basis by cloud computing service providers (CSPs). Data storage is one of the services of cloud computing. Data Security is important concern in cloud. Confidentiality, Integrity, and Availability (CIA) are some security dimensions. In this paper, we are providing an improved technique to provide confidentiality of data. The proposed encryption and decryption algorithm achieves better time and storage complexity than the existing ELGamal algorithm. We have implemented this algorithm in Java and run this in different data set available in internet. © 2014 Springer International Publishing Switzerland.
