As cyber-attacks and functional safety requirements increase in Operational Technology (OT), implementing security measures becomes crucial. The IEC/IEEE 60802 draft standard addresses the security convergence in Time-Sensitive Networks (TSN) for industrial automation.We present the standard’s security architecture and its goals to establish end-to-end security with resource access authorization in OT systems. We compare the standard to our abstract technology-independent model for the management of cryptographic credentials during the lifecycles of OT systems. Additionally, we implemented the processes, mechanisms, and protocols needed for IEC/IEEE 60802 and extended the architecture with public key infrastructure (PKI) functionalities to support complete security management processes.
The provisioning of security for highly dynamic wireless networks, as for Car2X applications is still a major topic, as very specific requirements have to be solved. Those include a perfect privacy level and advanced real-time behavior, and the necessity to work with a public infrastructure (PKI) to support secure authentication.
This contribution analyzes these requirements, discusses the existing approaches, performs a gap analysis and elaborates on proposals to fill these gaps. It describes work in progress within the KoFAS-initiative for the development of a cooperative pedestrian protection system (CPPS).
