多安全域环境下的访问控制是域间进行协作必须要解决的问题之一。交互主体间的陌生性以及共享资源的敏感性成为跨域建立信任关系的主要障碍。自动信任协商的提出提供了解决这一问题的新途径,它通过协作主体间信任证和访问控制策略的反复交互披露,在资源的请求者和提供者之间自动地建立起信任关系。在分析现有自动信任协商技术的基础上,针对信任协商中存在的证书敏感属性信息泄露的问题提出了改进的方案。该方案可有选择性地披露信任证的敏感属性,从而达到协商过程中减少敏感信息泄露和提高协商系统抗攻击能力的目的。 相似文献

Vendors and clients collaborate on outsourcing projects through virtual teams. Trust is an important indicator of mutual relationships that lead to successful projects. This study’s objective is to investigate the determinants of trust in different stages of collaboration during offshore software-development outsourcing. Using a case study approach to collect data, we find that reputation, a cognition-based trust factor, influences clients’ trust in vendors in the team-forming stage. Responsible team climate, a knowledge-based trust factor, impacts clients’ trust in vendors in the team-storming and norming stages of software design and development. Structural assurance, an institutional trust factor, encourages vendors’ trust in clients in the same team-storming and norming stages of software design and development. Benefit, a calculative-based trust factor, influences vendors’ trust in clients in the team-performing stage of software delivery and implementation. Our research findings have implications for software-outsourcing collaboration theories and practices and may have implications beyond that sphere, including team building in multiple contexts and environments. 相似文献

The evolution of trust in information technology alliances 总被引：2，自引：0，他引：2

As strategic alliances become an increasingly important weapon for companies in achieving a competitive advantage, an important subject of investigation has become those factors that contribute to the success of the alliance. Trust between the alliance partners has been proposed to be one of those critical success factors. The high levels of uncertainty and interdependence that characterizes high technology alliances make trust particularly important in these contexts. Very little is known, however, about the process of trust creation or erosion in strategic alliances. This study addresses this shortcoming in cross-sectional trust research by utilizing a longitudinal survey design to examine the antecedents and outcomes of trust formation between strategic alliance partners. We contrast a transaction cost economics view of trust with a social exchange perspective to more fully explore what may influence changes in the level of trust between partners. Results suggest that the development of trust was not a function of the formal incentive systems that transaction cost economists deem necessary to prevent opportunistic behavior. Conversely, factors from social exchange theory – communication, shared values, and relationship equity – provide a more thorough explanation of what contributes to the development of higher levels of organizational trust. Finally, this study provides evidence that as trust increases between partners, the alliance benefits by displaying higher levels of dependence, higher levels of partner learning, and higher levels of performance. 相似文献

Effects of various characteristics of social commerce (s-commerce) on consumers’ trust and trust performance 总被引：1，自引：0，他引：1
The development of social networking sites (SNSs) has given rise to a new e-commerce paradigm called social commerce (s-commerce). S-commerce is a subset of e-commerce and uses SNSs for social interactions and user contributions to facilitate the online buying and selling of various products and services. Recent years have witnessed the rapid growth of s-commerce in Korea, but this growth has involved a number of transaction-related issues such as no delivery and the delivery of wrong items. In particular, consumers’ trust has become a crucial factor in the success of s-commerce firms, requiring these firms to make more effort to gain this trust. In this regard, this study identifies the key factors in s-commerce [reputation, size, information quality, transaction safety, communication, economic feasibility, and word-of-mouth (WOM) referrals], that is, the characteristics of s-commerce influencing Korean consumers’ trust in s-commerce. In addition, the study assesses the effects of trust on trust performance (purchase intentions and WOM intentions). The results of an empirical analysis based on a sample of 371 s-commerce users indicate that all the characteristics of s-commerce (except for economic feasibility) had significant effects on trust and that trust had significant effects on purchase and WOM intentions. The results have important implications for s-commerce firms wishing to develop a successful business model for providing their customers with trustworthy services. 相似文献

The roles of habit and web site quality in e-commerce 总被引：1，自引：0，他引：1
Previous research has primarily examined consumers’ perceived usefulness of web sites and trust in the web retailer as two major predictors of web site use and e-commerce adoption. While the consumers’ repeated behavior in the past (i.e., habit) may contribute to continuance behavior, it has not been investigated. This article includes habit as a primary construct along with perceived usefulness and trust to predict and explain consumers’ continued behavior of using a B2C web site. Additionally, included are several web quality measures as antecedents to trust and perceived usefulness. The research model is evaluated using structural equation modeling. Results show that consumers’ behavioral intentions to continue using a B2C web site are determined by all three key drivers: perceived usefulness, trust, and habit. Furthermore, not all dimensions of web quality have a significant effect on perceived usefulness and trust. 相似文献

Social commerce has evolved quickly in practice and gained attention in the IS discipline. However, trust has remained a vital component and is dominantly worth investigating. The purpose of this study, therefore, is to examine the roles of social commerce constructs and social support constructs (i.e., emotional support and informational support) in establishing trust on online community platforms. The study will apply the theoretical foundation of social commerce constructs proposed by Hajli. In order to provide a detailed understanding of the proposed model, a quantitative study involving a survey data gathered from online communities in Malaysia, including Facebook, Trip Advisor and LinkedIn was conducted. The data was analyzed and hypotheses were tested with structural equation modeling (SEM). Our results shed some lights on social commerce literature. The findings show that there are significant effect of social commerce constructs on social support, namely the emotional and informational support, and in turn, on trust- building. 相似文献

With the proliferation of e-commerce, a large part of online shopping is attributed to impulse buying. Hence, there is a particular necessity to understand impulse buying in the online context. Impulse shoppers incline to feel unable to control their tendencies and behaviors from various stimuli. Specifically, online consumers are both the impulse shoppers and the system users of websites in the purchase process. Impulse shoppers concern individual traits and system users cover the attributes of online stores. Online impulse buying therefore entails two key drivers, technology use and trust belief, and the mediator of flow experience. Grounding on flow experience, technology-use features, and trust belief, this study proposes a novel research model to examine impulse buying behavior in a complete manner. Data were collected from an online survey. Data analysis considers structural equation modeling technique with formative structure. Empirical results showed that flow experience is an important factor to affect impulse buying from its original drivers. Trust belief is also critical to impulse buying as perceived usefulness is not. Implications for managers and scholars are further discussed. 相似文献
