Today’s electronic systems face important problems of security and trust. In a paperless e-business environment, the lack of legal documents with signatures and other identification proof of authorized business entities introduce the problem of non-repudiation and security which arises as a result of lack of trust. Proper mechanism to ensure trusted ebusiness transactions is a much-felt need of...

Service-oriented Architectures (SOA) facilitate the dynamic and seamless integration of services offered by different service providers which in addition can be located in different trust domains. Especially for business integration scenarios, Federated Identity Management emerged as a possibility to propagate identity information as security assertions across company borders in order to secure...

The efficiency of e-commerce can be increased through the usage of intelligent agents which negotiate and execute contracts on behalf of their owners. The knowledge of trust to secure interactions between autonomous agents is crucial for the success of agent-mediated e-commerce. Building a knowledge sharing network among peer agents helps to overcome trust-related boundaries in an intelligent e...

Previous work has used theories of evidence to incorporate belief into trust and reputation systems. Some important questions that remain, however, are how agents might recover reputation lost in disputed transactions, and how new agents with little or no past transaction history might enter the trust network. We attempt to address these issues by extending previous work using the Dempster-Shaf...

An attack-resistant trust management scheme (ART) is proposed for VANETs that is able to detect and cope with malicious attacks and also evaluate the trustworthiness of both data and mobile nodes in VANETs. Specially, data trust is evaluated based on the data sensed and collected from multiple vehicles. Node trust is assessed in two dimensions, functional trust recommendation trust. The effecti...

Trust management and trustworthy computing are becoming increasingly significant at present. Over the recent years there have been several research works that have addressed the issue of trust management in distributed systems. However a clear and comprehensive definition that can be used to capture a range of commonly understood notions of trust is still lacking. In this paper, we give a forma...

Cryptography and Authentication is the traditional approach to provide security in WSNs(Wireless Sensor Networks). However, that conventional approach is not sufficient for the unique characteristics and novel misbehaviors encountered in WSNs. In this paper, we use a general tool which has been used in economics, statistics and data analysis. With this approach, we propose a task-based trust ma...

Trust management is an extensively investigated topic. A lot of trust models and systems have been proposed in the literature. However, a universally agreed trust model is rarely seen due to the fact that trust is essentially subjective and different people may have different views on it. We focus on the personalization of trust in order to catch this subjective nature of trust. We propose a mu...

Trust represents an important issue for adopting cloud services. A trust management framework is essentially, about user rating. Hence, correctly addressing user feedback and filtering out malicious rating is a main step in providing reliable services. In order to process their feedback and calculate a reliable trust degree. Thus, new opportunities can be offered for the establishment of a trus...
