A Framework for Assessing Security Strength of Cloud Computing Service

Abstract

Cloud computing is mentioned to evolve dynamically and cloud transformation is getting easier all the time. Different cloud aspects are emerging in an efficient manner and have the potential to transform the traditional way of computing. With the advent of data sharing in cloud computing, the demand for outsourcing data has rapidly increased in the last decade. However, several security and privacy challenges exist impeding the acceptance of cloud computing. A highly secure system is required to guard an organizational entity, its resources, and assets. In this article, we propose and implement a novel architecture, the first of its kind, providing an enhanced level of security for outsourcing data in a cloud computing environment consisting of multiple independent cloud providers. The framework consists of dual encryption combining Homomorphic encryption at the client end and Blowfish cryptographic technique at the server side for authorization. The diverse security issues associated with information integrity, security, confidentiality, and authenticationmust be addressed. Simulations and analysis were performed on an Oracle virtual machine Virtual-Box and a Fog environment on Ubuntu 12.04 platform. Extensive safety measures and performance analysis considering the Encrypted file size and Encryption time demonstrate that our projected proposal is vastly proficient and satisfies the requirements for secure data sharing.
