Workshop on CCAM Trust Assessment for Safety and Security, took place on Wednesday, December 11, 2024, 09:00 – 16:00 (CET), in a hybrid mode, online and in Ulm University, Ulm, Germany .
The workshop was organized by Frank Kargl & Dennis Eisermann on behalf of the CONNECT (EU-funded) and ConnRAD (funded by the German Federal Ministry of Research and Education) and Dr. Michael Buchholz on behalf of the EVENTS and PoDIUM EU projects.
The workshop discussed the usage of Subjective Logic for Trust Assessment in Security and Safety and brought up open research questions how to possibly bring theses areas together in one overall framework.
Its aim was to advance the methods for assessing trustworthiness in complex, interconnected systems. While frameworks based on propositional logic, such as Subjective Logic, are widely used to evaluate the trustworthiness of nodes and data in various systems, a key challenge remains in the fact that such assessments often focus on specific areas like security or safety. However, from a practical standpoint, the reduction of trustworthiness, whether due to security breaches or data inaccuracies, is a critical issue. It is essential that untrustworthy data is either not relied upon or is used with a sufficient safety margin to prevent adverse outcomes. A framework capable of assessing trustworthiness across multiple domains could provide significant advantages while minimizing resource requirements compared to conducting separate assessments for each individual area of concern.
From EVENTS, Mr. Thomas Griebel gave a short lightning talk on Ulm’s work, within EVENTS.
