Wireless networks are prone to certain information security threats that are either unique, or more pronounced for them due to the open air nature of the channel, bandwidth limitations and constantly changing topology. The concept of trust management, i.e., establishment of trust combined with trust monitoring, can be useful for mitigating the consequences of a substantial number of these threa...

The wireless sensor network is an emerging technology, which is used to sense and monitor the environment. As the nodes are deployed in an open environment, the security is one of the essential factors. The cryptography techniques can ensure confidentiality, integrity and authentication. However, wireless sensor network also needs to deal with inside and outside attackers. To deal with outside ...

The interactions among peers in Peer-to-Peer systems as a distributed collaborative system are based on asynchronous and unreliable communications. Trust is an essential and facilitating component in these interactions specially in such uncertain environments. Various attacks are possible due to large-scale nature and openness of these systems that affects the trust. Peers has not enough inform...

This chapter introduces trust modeling and trust management as a means of managing trust in digital systems. Transforming from a social concept of trust to a digital concept, trust modeling and management help in designing and implementing a trustworthy digital system, especially in emerging distributed systems. Furthermore, the authors hope that understanding the current challenges, solutions ...

We identify the trust management problem as a distinct and important component of security in network services. Aspects of the trust management problem include formulating security policies and security credentials, determining whether particular sets of credentials satisfy the relevant policies, and deferring trust to third parties. Existing systems that support security in networked applicati...

Internet of Things (IoT) is going to create a world where physical objects are seamlessly integrated into information networks in order to provide advanced and intelligent services for human-beings. Trust management plays an important role in IoT for reliable data fusion and mining, qualified services with context-awareness, and enhanced user privacy and information security. It helps people ov...

Trust is an important aspect of decision making for Information Systems and particularly influences the specification of security policies. However, trust is a complex concept that is difficult to define precisely, and a wide variety of definition of trust have been put forward. Over last ten years, a number of trust management language have been developed to express security statements in a di...

Trust is situation-specific and the trust judgment problem with which the truster is confronted might be, in some ways, similar but not identical to some problems the truster has previously encountered. The truster then may draw information from these past experiences useful for the current situation. We present a knowledgeintensive and model-based case-based reasoning framework that supports t...

These day, supply chains (SCs) have become more and more complicated and have extensively expanded and due to these complexities, the supply chain management (SCM) has encountered several uncertainties, and, as a result, trust and assurance between members in SCs has become essential for a successful SCM. Although trust is an inevitable component in nearly all fields in SCs, like cooperation, c...

Concern about vulnerabilities of IT systems is growing together with attention to risks of intrusive cyber-control over personal activities and data. This article discusses some new technologies that are being integrated into computing devices for realizing so-called Trusted Computing and Digital Rights Management systems, which can remotely attest their current hardware/software state and can ...
