We investigate trust propagation in delegation situations, which often occur in hierarchical organisations and coalition structures. In doing so we define a delegation chain representing the sub-delegation process. Such delegation chains present a problem for current trust evaluation mechanisms, which are unable to accurately divide trust among the chain members, resulting in degraded system pe...

IS research has shown the importance of trust in domains such as e-commerce or technology acceptance. Researchers also emphasize the importance of the identification of factors that influence trust. Unfortunately, the currently dominant reflective measurement does not offer these insights, and thus this contribution aims at developing a formative measurement model for trust. To achieve this, we...

We also extend the concept of Schneider’s enforceable security policy...

Nowadays one of the most important challenges for integrated systems such as social networks is the evaluation of trust for agents which are interacting with each other in the environment. It plays an important role that the trust has been evaluated from the agent’s experiences. In this paper, we propose a new mathematical approach based on the entropy of Dirichlet distribution, to model the ag...
