The Internet of Things (IoT) and social networking integration, create a new concept named Social Internet of Things (SIoT) according to which the things are able to autonomously establish social relationships with regard to the owners. Things in SIoT operate according to a service-oriented architecture. There may be misbehaving owners and consequently misbehaving devices that can perform harmf...

Computational Trust and Reputation (CTR) systems are platforms capable of collecting trust information about candidate partners and of computing confidence scores for each one of these partners. These systems start to be viewed as vital elements in environments of electronic institutions, as they support fundamental decision making processes, such as the selection of business partners and the a...

Mobile devices may share resources even in the presence of untrustworthy devices. To do so, each device may use a computational model that on input of reputation information produces trust assessments. Based on such assessments, the device then decides with whom to share: it will likely end up sharing only with the most trustworthy devices, thus isolating the untrustworthy ones. All of this is,...

With the gradually opening up of the network environment, trust mechanisms for information security are increasingly becoming an important prerequisite and foundation. Fuzziness and uncertainty are two basic features of trust. The qualitative and quantitative transform model--Cloud model is applied to the trust evaluation, and a Cloud-Based Weighted Trust Model (CBWT Model) is proposed, includi...

As Mobile ad hoc networks (MANETs) deployed in adversary environments. There are several routing protocols required to switch data from one node to another but nonetheless they venerable from variety of attacks. Trust model, an abstract psychological perceptive process, is one of the utmost multifarious perceptions in social relationships, concerning factors such as expectations, potentials and...

Using panel data method, this study examines the effects of different dimensions of social capital on innovation at the societal level across 21 countries (19 Asian countries plus Russia and Egypt) for the period 1995-2011. Dimensions of social capital that have been considered in this study include generalized trust, trust toward friends, institutional trust, civic participation, and norms of ...

In order to ensure the reliability and credibility of the data in wireless sensor networks (WSNs), this paper proposes a trust evaluation model and data fusion mechanism based on trust. First of all, it gives the model structure. Then, the calculation rules of trust are given. In the trust evaluation model, comprehensive trust consists of three parts: behavior trust, data trust, and historical ...
