Abstract: A process control system is disclosed which can include a plurality of spatially distributed, internetworked network subscribers with secure communication between the network subscribers via a communication network. Communication integrity can be based on an interchange of certificates. In order to protect the communication integrity, the process control system can include a central certification point which is an integral part of the process control system and allocates and distributes certificates.
