This paper presents a proof of concept demonstrating that centralized key management canrneffectively support group key distribution for avionics communication patterns. The proposed approach introduces two modifications to the avionics platform architecture. In contrast, classical key negotiation mechanisms such as TLS require each IMA computer tornperform its own key negotiation.
