Abstract

Cloud computing is the concept of using a virtual pool of resources to provide users with solutions to various computing problems via the internet. IT services are provided on an on-demand basis, which are accessible from anywhere, anytime through authorized users. “Storage as a Service” is one of the major services for the end users where sensitive data is stored in the cloud. As a result, data vulnerability becomes a common phenomenon where exploitation occurs through the provider or unauthorized users. So, data protection is the heart of data security where encryption algorithms play a major role. The greater complexity of these algorithms makes it more secure and safe compared to the other techniques. This chapter presents a few of the well-known encryption-decryption-based algorithms which are aimed at protecting cloud stored data from unauthorized access.

Keywords: Cloud computing, encryption algorithm, data security

1.1 Introduction

Cloud computing, which is the next-generation paradigm in computation, delivers applications and resources on an on-demand basis via the internet as services [1]. It provides an ...
