When security-critical applications are considered to be integrated into the building automation domain, two requirements need to be fulfilled: providing security features at the network level and support for security mechanisms at the application level. This paper tackles the second goal using domain knowledge based on existing and related international application level standards. After the demands...
Building automation systems are traditionally concerned with the control of heating, ventilation, and air conditioning, as well as lighting and shading, systems. They have their origin in a time where security has been considered as a side issue at best. Nowadays, with the rising desire to integrate security-critical services that were formerly provided by isolated subsystems, security must no longer...
Many applications such as distributed measurements or real-time networks benefit from a common notion of time. Protocols providing high precision and simple clock synchronization are necessary to achieve such a common time base. However, most of the available protocols are lacking with regard to fault tolerance and performance in case of a fault. The project IMAGINE (Introduction of Master Group Based...
