Ensure functional security for connected and autonomous cyber-physical systems – the SAFSEC-CPS project
Systems that have traditionally been closed will now be more open to take advantage of the progress in communications infrastructure and cloud services. Many systems can therefore no longer be considered as separate units, with no regard to the environment they operate in, but as part of a larger system. Many systems are also connected to the Internet, and it must be considered that all other systems connected may potentially affect each other.
At collaborative systems are becoming increasingly linked, more and more systems become partially or completely autonomous. This applies, for example, to factory machines, different types of robots, surveillance equipment, drones, cars, buses, trucks, agricultural equipment and industrial vehicles.
Autonomous and cooperative systems are expected to increase production efficiency and potentially completely replace human efforts in hazardous and harmful environments. The prerequisite for systems of this type is that they are reliable, responsive and above all safe for persons and property that may be affected by the systems.
In order to guarantee the security of open, cooperative and autonomous systems, it is no longer possible to analyze functional security in a traditional manner, i.e. independent of other systems, in accordance with standards such as IEC 61508, IEC 62304, IEC 61513, ISO 25119 and ISO 26262. Functional security of these systems is now undoubtedly dependent on cyber security. Thus, they cannot be analyzed individually.
“The aim is to find a common model for analysis of functional security and cybersecurity in complex autonomous cyber-physical systems.”
