Nowadays, Wireless Sensor Networks are mature enough to be used by Business Applications. These applications rely on trustworthy sensor data to control business processes. We propose an approach to assess the trustworthiness of sensor data during its lifecycle from acquisition on the node, over processing and to routing to the Business Application. We rely on the Subjective logic framework to compute the probability that sensor data are trustworthy enough to be used by an application. With the
more » ... efinition of new operators for the subjective logic, we develop a trust model, that allows to detect erroneous sensor data which are originated either unintentionally by malfunctioning of sensor nodes or intentionally by attackers.
