Research and implementation of a role-based trustworthiness mechanism for IaaS

Abstract

Despite the advantages brought by cloud computing, security issues have emerged as one of the most significant barrier to faster and more widespread adoption of it. Therefore, this paper focused on the trustworthiness of infrastructure as a service (IaaS) and proposed a role-based trustworthiness mechanism to ensure that the different roles in IaaS architecture are trusted. What's more, this paper also considered the interactions between different roles in cloud environment and designed relevant validation protocols. Our experiments also show that this trustworthiness mechanism is practical in terms of performance.
