Trust management is an emerging technology to facilitate secure interactions between two communicating entities in distributed environments where the traditional security mechanisms are insufficient due to incomplete knowledge about the remote entities. With the development of ubiquitous computing and smart embedded systems, new challenges and threats come up in a heterogeneous environment. Trust management techniques that depend on a centralized server are not feasible in wireless peer-to-peer communication networks. Hence, the trust management and modeling strategies are becoming increasingly complex to cope with the system vulnerabilities in a distributed environment. The aim of this chapter is to have a thorough understanding of the trust formation process and the statistical techniques that are used at different stages of the trust computation process. The functional components of a trust management framework are identified and some of the existing statistical techniques used in different phases of the trust management framework are analyzed.

Trust is a firm belief over a person or a thing in distributed environment based on its feedback on review based on its performance by others. Similarly, in cloud, trust models play an important role in solving various open challenges in cloud environment. This chapter showcases all such issues that can be solved by trust management techniques. This work discourses various trust management models and its categorization. The work discourses existing work using trust models from the field of grid computing, cloud computing, and web services because all these domains are sub child of each other. The work provides an abstract view over all trust models and find the suitable one for cloud and its future prospects.

Root Of Trust

One of the key mechanisms for trust establishment among different platforms is remote attestation, which allows a platform to vouch for its trust related characteristics to a remote challenger. In this chapter, the authors propose a new conceptual model for remote attestation consisting of four basic ingredients: root of trust, attestation objective, object measurement, and attestation process. With this model, they present a systematic study on the remote attestation, including the methodologies applied for implementing the four elements and the principles for designing an attestation scheme. The authors also examine existing remote attestation schemes in the literature by grouping them into two main types: integrity attestation and quality attestation. They discuss both the strength and the limitations of each type of scheme and explain how they can be applied in trust management in distributed environment.

Information technology has changed the way organizations function. This resulted in the reliance of help desks to deal with information technology related areas such as hardware, software, and telecommunication. Besides, the adoption of business process reengineering and downsizing has led to the shrinkage of the sizes of help desks. Consequently, the help desks have to cover more information technology products and resolute more technical enquiries with less staff. Thus, the outcome is clear that users have to wait comparably longer before the help desk staff are available to offer assistance. This chapter describes the development of help desk, ranging from help desk structures to support tools. This chapter also discusses the application of knowledge management techniques in the development of a proposed conceptual knowledge management framework and a proposed redistributed knowledge management framework. While the conceptual knowledge management framework proposes a standard methodology to manage help desk knowledge, the proposed redistributed knowledge management framework allows simple and routine enquiries to be rerouted to a user self-help knowledge management system. The proposed system also enables help desk to provide technical knowledge to users 24 hours a day, 7 days a week. Regardless of time and geographical restrictions, users can solve their simple problems without help desk intervention simply by accessing the proposed system through portable electronic devices.
