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).
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.
