Open-Source OPC UA Security and Scalability

TUM and Framatome published a new article on OPC UA at the 25th IEEE International Conference on Emerging Technologies and Factory Automation, ETFA 2020!

OPC UA is a popular machine-to-machine communication protocol widely adopted in industrial environments. As it is mostly used for remote monitoring/control, compromising OPC UA can lead to compromising entire production facilities. Thus, OPC UA is designed with a high level of security in the specification. Major commercial OPC UA implementations have compliance certificates ensuring that their security models obey the specification. However, open-source OPC UA implementations that have wide deployment mostly lack these certificates.

The article compares the security models of the most commonly used open-source implementations. Furthermore, their scalabilities for the number of clients and OPC UA nodes are also analyzed.
