Due to the characteristics of an ad hoc network without a control center, self-organization, and flexible topology, the trust evaluation of the nodes in the network is extremely difficult. Based on the analysis of ad hoc networks and the blockchain technology, a blockchain-based node-level trust evaluation model is proposed. The concepts of the node trust degree of the HASH list on the blockchain and the perfect reward and punishment mechanism are adopted to construct the node trust evaluation model of the ad hoc network. According to the needs of different applications the network security level can be dynamically adjusted through changes in the trust threshold. The simulation experiments demonstrate that ad-hoc on-demand distance vector(AODV) Routing protocol based on this model of multicast-AODV(MAODV) routing protocol shows a significant improvement in security compared with the traditional AODV and on-demand multipath distance vector(AOMDV) routing protocols.

Trust and trustworthiness of web services and organizations is calculated as scalar values. But there is still a certain level of risk for the overall reliability of this value. In this article, we focus on calculating trust values as intervals between upper and lower bounds based on predefined confidence values through an additional confidence probability. This will give us a more realistic approach to the trust assessments between individuals and organizations. We also developed a web-based software tool, TAST (Trust Assessment Software Tool) that collects the web services' evaluation of different customer groups for similar organizations through the user interface and calculates the trust intervals for predefined and previously selected confidence values. Our model uses a weighted calculation of mean and variances of customer groups in specific periods and analyses the total and incremental trust of different customer groups.

Trust and perceived usefulness have been variables frequently used by IS researchers to explain consumers' online transaction intention. A group of prior studies have incorporated the two variables simultaneously to build better models to capture the phenomenon. However, the studies have largely ignored the role of trust by replacing trust with trustworthiness. The purpose of this study is to fill this gap. To do this, the study conceptualizes and tests relationships between trust, perceived usefulness and related variables. Based on the study results, the study discusses that trust and trustworthiness are distinct and have causal relationships, the dimensions (ability, integrity, and benevolence) of trustworthiness are related but theoretically distinct, and trust performs a mediating role within its nomological network.

The importance of communities of practice(CoP) as an organizational informal unit for fostering knowledge transfer and sharing gains a lot of attention from KM researchers and practitioners. Since most of CoPs are formulated online these days, the credibility or trustworthiness of knowledge contents circulated within a certain CoP should be considered thoroughly for them to be fully utilized safely. Here comes the need for an appropriate trust measuring methodology to determine the true value of knowledge given by unknown people through an online channel. In this paper, an improved trust measuring method is proposed using new trust variables such as level of degrees derived from the relationships among community users. In addition, activeness, relevance, and usefulness of the knowledge contents themselves, which are calculated automatically using a text categorization technique, are also used for trust measurement. The proposed framework incorporates fuzzy set and calculation concepts to help build trust matrices and models, which are used to measure the level of trust involved in specific knowledge artifacts concerned.

We are sometimes interacting with people who we know nothing and facing with the difficult task of making decisions involving risk in social network. To reduce risk, the topic of building Web of trust is receiving considerable attention in social network. The easiest approach to build Web of trust will be to ask users to represent level of trust explicitly toward another users. However, there exists sparsity issue in Web of trust which is represented explicitly by users as well as it is difficult to urge users to express their level of trustworthiness. We propose a fuzzy-based inference model for Web of trust using user behavior information in social network. According to the experiment result which is applied in Epinions.com, the proposed model show improved connectivity in resulting Web of trust as well as reduced prediction error of trustworthiness compared to existing computational model.

The purpose of this research is to identify the factors affecting user acceptance of mobile banking. To test the hypotheses, this research incorporates trust to extend the model. This study investigates the causal relationship among four factors; perceived ease of use, perceived usefulness, trust, and intention to use in mobile banking. This study also identifies the elements by which these factors are influenced. The result finds that facilitation condition and self-efficacy are significant elements affecting perceived ease of use. System quality, perceived ease of use and trust are significant elements affecting perceived usefulness, However, social influence is found to be not significant. System quality and perceived ease of use are significant elements affecting trust. Conclusively, perceived ease of use, perceived usefulness and trust are significant factors affecting the user acceptance in Mobile banking.

Blog have become very popular with Internet users as one of the latest forms of online communication as well as knowledge sharing tools. However, blogs generate growing concerns regarding information privacy issues. This study, based on social exchange theory, presents results about bloggers' information sharing behavior. The 157 surveys are collected from a large university in the eastern U.S. The survey results indicate that trust which has four second order factors: economy based trust, trust in reciprocity, trust in other bloggers and trust in social interaction positively affects bloggers' information sharing behavior. However, online information privacy concerns have a negative impact on the relationship between trust and bloggers' information sharing behavior.

This study examines the dynamics of trust and distrust at different price levels. We first note that trust and distrust are built with cognitive and affective foundations, and price is viewed as a financial burden or product quality information. Then, we relate price changes to trust and distrust, and hypothesize their interactions: price as a quality cue will positively moderate the cognitive dimension of trust, whereas price as financial burden will negatively moderate the affective dimensions of trust and distrust. We surveyed 263 online mall shoppers in Korea. Among our eight hypotheses, six are fully supported and two are partially supported. The result shows that price perception interacts with both the cognitive and affective dimensions of trust and distrust, but its specific impacts are distinguished by the price perceptions, whether it is financial burden or product quality information.

Lack of trust is major reason for many company to take a cautions stance towards business-to-business electronic commerce. Especially innovative business models such as online business-to-business marketplaces face the lack of not only having to give their members and partners faith own capabilities and reliability, but also to ensure that the respective parties interacting through them have trust in each other. This paper is empirical study on the trust factors affecting the repurchase intentions in a B2B e-Marketplace by survey instrument based on Likert-style 5 point measurement scale. The objective of this paper is evaluation of relationship between repurchase intentions and trust. The focus of this paper is the antecedents and consequences of buyer trust in a B2B e-Marketplace, not trust intermediaries or in third parties that might mediate between the buyer and e-Marketplace. The findings of this study are expected to increase the awareness of B2B e-Commerce adopter and implementers about the importance of trust in e-commerce participation.
