B3.3 - Encryption of Packet Telemetry: A Risk Analysis
Cédric Tavernier, Jean-Guy Pierozak · 2024
Telemetry systems are evolving from Continuous Streaming (IRIG106-CH4) to Packet Streaming (IRIG106-CH10, iNET, TmNS…), resulting in the latest version of IRIG106-CH7 mixing both.In Telemetry, packet streaming relies on UDP protocol which is unidirectional and allows some loss of packets.Besides, the need to secure the confidentiality of TM data is growing, leading to cipher part or all of it.We propose in this paper to start build a solution from a rigorous risk analysis.A description of state of the art solution compliant with the risk analysis results will be performed.
