In this paper, we develop a trust based security protocol based on a cross-layer approach which attains confidentiality and authentication of packets in both routing and link layers of MANETs. In the first phase of the protocol, we design a trust based packet forwarding scheme for detecting and isolating the malicious nodes using the routing layer information. It uses trust values to favor pack...

Multi-agent systems are open, anonymous and dynamic in nature. Trust and reputation models fail to properly evaluate the trust of an agent if malicious agents behave in an unpredictable way. These models are ineffective in providing quick response to malicious agent’s oscillating behavior and critical for sustaining good service quality .The dynamic trust computation model called Secured Trust ...

Trust establishment in networks is the essential foundation for follow-on security mechanisms, such as key management and secure transmission. In this paper, we concentrate on self-organized, distributed and resource-constraint networks which pose formidable challenges on trust establishment due to lack of infrastructure and centralized servers. We model our trust establishment strategy as a lo...

It is well known that some XML elements correspond to objects (in the sense of object-orientation) and others do not. The question we consider in this paper is what benefits we can derive from paying attention to such object semantics, particularly for the problem of keyword queries. Keyword queries against XML data have been studied extensively in recent years, with several lowest-common-ances...

Today a large amount of RDF data is published on the Web. However, the openness of the Web and the ease to combine RDF data from different sources creates new challenges. The Web of data is missing a uniform way to assess and to query the trustworthiness of information. In this paper we present tSPARQL, a trust-aware extension to SPARQL. Two additional keywords enable users to describe trust re...
