Abstract
Cloud computing is situating its position in the market as the next disruptive utility paradigm based on the pay as you use model. It is changing the way information technology (IT) operates from individuals and companies’ perspectives. Cloud computing comes with different offerings to accommodate diverse applications. Security concerns are what’s making many companies reluctant from fully embracing the cloud realm. To enhance trust and entice adoption between cloud clients (CC) and cloud service providers (CSP), cloud computing based on a third-party auditor (TPA) has been introduced. Hence introducing a solution with a TPA, comes with its toll in terms of trust and processing overhead. A light-weight security protocol to give the CC an extra control with tools to audit the TPA and the CSP is paramount to the solution. In this paper, we are introducing a novel protocol: Light-weight Accountable Privacy Preserving (LAPP) Protocol. Our proposed protocol is based on a novel mathematical model along with three algorithms. We have conducted simulation experiments to measure the impact of our method, compared to the most eminent privacy preserving methods, using the GreenCloud simulator. Our results showed superiority in performance for LAPP concerning time complexity, accuracy, and computation time on auditing.
