A Proposed Model for Trust Management: Insights from a Simulation Study in the Context of Cloud Computing

Abstract

In computing systems, one of the centric topics entails cloud computing. This dominance is attributed to the crucial role that the concept plays in the daily lives of individuals, especially in the wake of the increasing adoption of technology by individuals and organizations. Indeed, the motivation behind the establishment, adoption, and implementation of cloud computing has been attributed to the need to offer low-cost and quick consumer service provision, as well as data manipulation and storage. However, the cloud environment continues to face security threats, a trend that informs the need for further investigations and analyses that could provide room for new system improvements. The current simulation study presents a dynamic model for security management in a cloud computing environment, with the central parameter involving electronic trust. Imperatively the proposed study examines interactions between the data provider and the data owner, as well as the end user. Specifically, the proposed model is that which ensures that for authentication purposes and access permissions, there is a continuous update of trust values. From the results, the model is flexible relative to the provision of dynamic access control, a positive trend that points to its promising level of efficiency.

Trust Metrics Model for Distributed System Access Control

“…The agents can communicate with each other, which improves the security and reliability of the system. There is a shortage of large expenditure [3]. Some researchers have studied the delegation technology in the distributed environment, and proposed to use the access control program (ACP) for delegation, so that users can access the services they need through an untrusted third party [4].…”
