MANET is a multi-hop network comprised of nodes that need to work in collaboration with each other for effective routing. But unfortunately, there is possibility of some nodes misbehaving for their own interests and disturbing the network. Therefore, reliability among nodes is very important in the network. Uncertainty is of prior importance, which deeply impacts a node's anticipation of others behavior...
Mobile Ad hoc NETworks (MANET) are the wireless networks of mobile computing devices without any support of a fixed infrastructure. Routing in MANET is based on mutual support of nodes in the network. But some nodes from the network acts maliciously, so the routing in network collapses. Most security schemes suggested for MANETs tend to build upon some fundamental assumptions regarding the trustworthiness...
In this paper we propose an enhancement of data integrity model. The proposed model is based on the idea of Biba integrity model but uses more elaborated integrity measurements. Since integrity can be seen as “trustworthiness of data and resources”, we propose to utilize trustworthiness opinions from subjective logic and express levels of integrity as levels of trustworthiness.
Large-scale data processing systems frequently require users to make timely and high-value business decisions based upon information that is received from a variety of heterogeneous sources. Such heterogeneity is especially true of service-oriented systems, which are often dynamic in nature and composed of multiple interacting services. However, in order to establish user trust in such systems, there...
Modern organizations increasingly depend heavily on information stored and processed in distributed, heterogeneous data sources and services to make critical, high-value decisions. Service-oriented systems are dynamic in nature and are becoming ever more complex systems of systems. In such systems, knowing how data was derived is of significant importance in determining its validity and reliability...
Vehicles will exchange much information in the future in order to efficiently maintain their inner model of the environment. Before they can belief received pieces of information, they must evaluate their reliability. Trust is a mechanism to estimate this reliability based on the sender. As cars often drive the same route, they meet each other again and again. They can establish friendship-like relations...
