Abstract

The objective of this research is to develop a scheme for improving cloud data confidentiality. A considerable number of people are sharing data through third-party applications in the cloud computing environment. According to reviewed literature, it has been realized that data security and privacy were the key challenges to the wider adoption of cloud services with insider threats being the most prevalent. Similarly, our online survey indicated that 53.3% of the respondents citing insider breaches as the main threat to their organizational data. The survey also confirmed that data security and privacy is one of the greatest barriers to the adoption of cloud services in their organization. Noting the flaws of Attribute-Based Encryption (ABE) and Identity-based encryption (IBE), and with the growth of computing power, applications are constantly being developed which makes them vulnerable to attacks. Since data confidentiality is essential in the provision of information security in the cloud, this paper suggested the development and the deployment of a hybrid attribute-based re-encryption scheme, which is a scheme that bridges the ABE and IBE, to secure data in the cloud computing environment.

Highlights

  • Widespread confusion has become lucid recently concerning the meaning of cloud computing (Daylami, 2016)

  • The survey was aimed at obtaining general information about cloud computing within their respective organizations before indulging in a series of experiments to evaluate the performance of the hybrid attribute-based re-encryption scheme schemes in practice

  • The research study would endeavor to identify the greatest threat to data confidentiality and privacy in the cloud computing environment before developing a data privacy scheme

Summary

Introduction

Widespread confusion has become lucid recently concerning the meaning of cloud computing (Daylami, 2016). Cloud data privacy as an element of security is constantly evolving owing to an ever-changing internet setting. In this information age, one of the greatest problems facing organizations is the failure to ensure data confidentiality and privacy and many organizations are not willing to adopt the unprecedented online demand services spearheaded by cloud computing. The Equifax leak is the most recent example that affected 146.6 million people, having names, birthdates, Social Security numbers, and addresses stolen. This scenario is just a one drop amidst a sea of poorly secured private information cases in the cloud computing environment. Coming from a public database exposing 198 million American voter records, and moving to FedEx leaking which exposed 119 000 scanned passports, driver licenses, and other personal documents on a publicly accessible server, the list seems to be endless
