This paper introduces and exemplifies a trade-off analysis of safety and security properties in distributed systems. The aim is to support analysis for real-time communication and authentication building blocks in a wireless communication scenario. By embedding an authentication scheme (TV-HORS) into a real-time communication protocol for safetycritical scenarios, we can rely on the protocol's individual safety and security properties. The resulting communication protocol satisfies selected

We look at handover situations in a IEEE 802.11 wireless setup between mobile nodes and access points. The trade-offs involve application-layer data goodput, probability of completed handover, and protocol slots per Access Point, to quantify the impact of security from a low-layer communication perspective on the communication protocols. The results are obtained using the network simulator ns-3.
