Towards a trust management system for cloud computing marketplaces: using CAIQ as a trust information source

Abstract

Cloud computing enables information technology related services in a more dynamic and scalable way than before—more cost‐effective than before due to the economy of scale and of sharing resources. Usually, cloud providers describe their promised behaviour—regarding functional and non‐functional aspects of the service provision—by way of service level agreements (SLAs). For different providers offering similar functionality, SLAs are often insufficiently claimable and inconsistent with the aspects considered important by customers. Therefore, customers face problems identifying a trustworthy cloud provider solely on the basis of its SLA. To support customers in reliably identifying trustworthy cloud providers, we propose a multi‐faceted trust management system architecture for cloud computing marketplaces and related approaches. This system provides the means for identifying trustworthy cloud providers in terms of different attributes, for example, compliance, data governance and information security. In this article, we present the first realization of our proposed trust management system using the Consensus Assessment Initiative Questionnaire, initiated by the Cloud Security Alliance, as one of the sources of trust information. In particular, our proposed approach contributes to the challenge of extracting trust information from Consensus Assessment Initiative Questionnaires completed by cloud providers. Finally, our implemented system and related approaches are experimented using real datasets. Copyright © 2013 John Wiley & Sons, Ltd.

Cloud-Based Utility Service Framework for Trust Negotiations Using Federated Identity Management

“…Reputation based models compute aggregated trust metrics based on the feedback received by different users based on their previous interactions. Prediction based trust management models are used when there is no prior information regarding the cloud based interactions [20].…”

Cloud Based RDF Security: A Secured Data Model for Cloud Computing

“…Creating metadata for the web is the fundamental objective of the RDF plan [10]. The mixture of many interconnected networks and PCs is known as the web, the vast majority of the presently best RDF stockpiling arrangements is bound to a solitary node [11,12]. The large scale RDF querying is the most critical part in the RDF data management, yet the substance and the structure of the client aren't effectively comprehended by the large scale RDF [13,14].…”

An Empirical Investigation on the Impact of Trust Mediated Determinants and Moderating Factors on the Adoption of Cloud Computing

“…The literature of cloud computing is rich with studies proposing trust management models for cloud computing based on different perspectives such as [1,[32][33][34]. Various researchers tried to survey such models and compare amongst them such as [35] while other tried to demonstrate the obstacles and challenges of developing cloud trust management systems such as [2,36].…”

“…Trust is one of the major and most critical factors that would prevent organizations adopting cloud computing. According to [1], Fujitsu Research Institute carried out a survey on cloud computing adoption and showed that 88% of consumers were worried about who have permission to access their data and 84% had concerns about the location of storing their data. In addition, [2] highlighted that trust management and security is one of the top 10 challenges and obstacles of adopting cloud computing.…”
