Existing identity metasystems provide enabling tools to manage, select, and control of digital identities but they have not provided the support of trust management that should cover how trust requirements associated with digital identities are modeled, how runtime conditions for trust are evaluated, and how the results of trust evaluation are consumed by systems/applications. In this paper, the authors propose an approach toward a trust management enabled identity metasystem that covers the analysis of trust requirements and the development of trust management system in a consistent manner. The proposed trust management architecture extends the existing identity metasystems by introducing computing components for carrying out typical trust management tasks associated with digital identities. The computing components in proposed architecture provide intelligent services for these tasks. The proposed high level architecture targets the automation of the development of the trust management layer for digital identities.

Trust is an abstraction of individual beliefs that an entity has for specific situations and interactions and it must evolve in a consistent manner so that it still abstracts the entity’s beliefs accurately. This paper presents and discusses a conceptual trust framework that models an entity’s trust as a relation whose state gets updated as relevant conditions that affect trust change. The proposed model allows entities to reason about the specification and adaptation of trust that is placed in an entity. An intuitive and practical approach is presented to manage end-to-end trust assessment for a particular activity, where multiple trust relationships are examined in a bottom-up evaluation manner to derive the overall trust for the activity. Finally, Hestia, a novel trust management system that conforms to the formal model’s principles, is described.

In this chapter, the authors propose an approach with a unified framework for trust management with a consistent way to cover a broad variety of trust mechanisms including credentials, reputation, local data storage, and environment parameters. The trust request, trust evaluation, and trust consuming are handled in a comprehensive manner. The framework has a high extensibility to embrace established standards and new requirements. With the help of the proposed framework, the development of a trust management system in the real world can be automated to a substantially high level.

Cloud computing is a model for enabling everywhere, suitable, on-demand network access. There are a number of challenges to provide cloud computing services and to accomplish this, it is necessary to establish trust across the cloud, between the user and the service provider. It is becoming increasingly complex for cloud users to make distinction among service providers offering similar kinds of services. There must be some mechanisms in the hands of users to determine trustworthiness of service providers so that they can select service providers with confidence and with some degree of assurance that service provider will not behave unpredictably or maliciously. An effective trust management system helps cloud service providers and consumers reap the benefits brought about by cloud computing technologies. Hence the objective of this chapter is to describe existing mechanisms that are used to determine a trust worthiness of a cloud service, various models that are used for calculating a trust value and method to establish trust management system.
