Trust plays an important role in making collaborative decisions about service evaluation and service selection in pervasive computing. Context is a fundamental concept in pervasive systems, which is based on the interpretation of environment and systems. The dynamic nature of context can strongly affect trust management and service selection. In this paper, we present a context-based trust mana...

Security and trust management in Vehicular Adhoc NETworks (VANET) is a crucial research domain which is the scope of many researches and domains. Although, the majority of the proposed trust management systems for VANET are based on specific road infrastructure, which may not be present in all the roads. Therefore, road security should be managed by vehicles themselves. In this paper, we propos...

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...
