Abstract
Techniques and architecture are described for dynamic security policy and key management for converged networks. More particularly, the techniques and architecture provide for configuring and managing converged industrial networks and configuring the converged industrial networks with respect to security policy and key management when also configuring and managing the converged industrial networks for operation. In configurations, the techniques and architecture described herein provide a method to establish dynamic access control as well as continuous trusted access and control based on well-defined streams and pre-calculated schedules. Additionally, in configurations, the techniques and architecture described herein provide a method to establish automated and integrated key management for controller-based time-sensitive networking (TSN) networks. This enables highly adaptable network security for operational technology (OT)/industrial Internet of Things (IIoT) networks used for critical processes such as automation and control.
