Should one use words or money to foster trust of the other party if no means of enforcing trustworthiness are available? This paper reports an experiment studying the effectiveness of two types of mechanisms for promoting trust: a costly gift and a costless message as well as their mutual interaction. We nest our findings in the standard version of the investment game. Our data provide evidence...

In the context of ambient networks, this article describes a cryptographic protocol called Common History Extraction (CHE) protocol implementing a trust management framework. All the nodes are supposed to share the same cryptographic algorithms and protocols. An entity called imprinting station provides them with two pairs of public/private keys derived from their identities. Also, two strange ...

REQUIRED) Uncertainty is a major problem in any supply chain. Inventory and excess capacities used to cope with uncertainty are significant cost drivers. Advanced information systems have been employed to support information exchange along the supply chain and were successful in synchronizing supply and demand and downsizing inventories. However, close cooperation requires mutual trust as a bas...

It has been consistently argued in prior research that mutual trust is essential for maintaining inter-organizational relationship quality and performance. The mirror side of trust – distrust – has received only scant attention, however. This empirical and qualitative study focuses on the roles of and relationships between trust and distrust in inter-organizational relationships. The results re...

Trust is a major aspect of decision making when two parties are involved, and the lack of face to face exchanges of the Internet deeply changes relations and behaviours regarding the available services. The already existing trust management systems over the Internet are one way only. Either they allow a provider to tell what it expects from a client (identification, qualifications), either it a...

This paper introduces the semantic of Multiparty Joint Authentication (MJA) into the authentication service, which is to find simplified or optimal authentication solutions for all involved principals through their transitive trust instead of to authenticate each pair of principals in turn. MJA is designed to support multiparty security contexts in grids with a specified, understood level of co...
