Investigation of security in cloud computing

Abstract

Cloud computing is a new and exciting field that is seeing an increase in activity and

interest, especially in recent years. The advantages of cloud computing is numerous

and well documented, and it seems increasingly likely that more and more companies

and people are adopting cloud technology for both business and personal use.

However, there are security issues which need to be properly addressed in order for

widespread adoption by users around the world to be possible.

This paper will look at the existing problems with cloud computing technology,

and current available solutions. It will then introduce fully homomorphic encryption

(FHE), one of the promising solutions to securing data level security in the cloud.

The author will conduct experiments on the FHE codes, and show that current implementations

of FHE is practically unfeasible. The author will also introduce how

FHE can be used to secure a simple generic cloud database application, and discuss

the timing and costing of securing a simple cloud based database using FHE.
