How Certain is Recommended Trust-Information

volker.fusenig@uni.lu ABSTRACT Nowadays the concept of trust in computer communications starts to get more and more popular. While the idea of trust in human interaction seems to be obvious and understandable it is very difficult to find adequate and precise definitions of the trust-term. Even more difficult is the attempt to find computable models of trust, particularly if one tries to keep all psycho-sociological morality from the real life out of the model. But, apart of all these problems, some approaches have been introduced with more or less success.
