Course Overview

For space system architects and mission security engineers. Covers end-to-end cryptographic architecture across spacecraft bus, payload, inter-satellite links, and ground segment. Addresses CCSDS SDLS and SLE protocol stacks, ESA ECSS standards, export control implications (EAR/ITAR), and quantum-resilient mission design.

Curriculum

Course content is structured into sessions below. Each session is configurable to your organisation's environment, threat model, and objectives.

#	Session	Topics
1	Space System Cryptographic Landscape Where cryptography lives in modern mission architectures
2	CCSDS Security Standards and PQC Readiness SDLS, SLE, and the path to quantum-resilient space protocols	CCSDS 355.0-B-2 Space Data Link Security (SDLS): encryption modes, authentication, key management limitations CCSDS Space Link Extension (SLE) cryptographic dependencies and cross-support interoperability NIST FIPS 203 (ML-KEM) and FIPS 204 (ML-DSA) applicability to CCSDS protocol stacks
Break
3	Spacecraft Bus, Payload, and Ground Segment Partitioning Mapping cryptographic boundaries across the mission architecture	Bus-to-payload cryptographic isolation: where PQC migration can and cannot be applied independently Ground segment attack surface: TT&C stations, mission control centres, key distribution infrastructure Inter-satellite link (ISL) security for constellation architectures: optical and RF link encryption
4	Interactive Demonstration: Cryptographic Inventory for a Reference Mission Full-day format only	Building a cryptographic inventory across a reference LEO mission: TC uplink, TM downlink, payload data, ISL Classifying algorithms by quantum vulnerability and mapping to CCSDS protocol layers Prioritising migration: which links face harvest-now-decrypt-later risk versus real-time command integrity risk
Break
5	Export Control and Regulatory Compliance EAR, ITAR, UK Export Control, and ESA ECSS alignment	EAR Category 5 Part 2 and ITAR Category XI: how PQC algorithm selection affects export classification ESA ECSS-E-ST-50C and ECSS-Q-ST-60C: standards alignment for European missions National cryptographic approval processes: ANSSI, BSI, NCSC guidance for space-grade PQC implementations
6	Migration Roadmap: On-Orbit and Pre-Launch Strategies Practical sequencing for missions at different lifecycle stages	Pre-launch missions: designing PQC-native cryptographic architectures from ground up On-orbit assets: crypto-agility retrofits, ground segment first migration, hybrid classical-PQC schemes Long-duration missions (15-25 year lifetimes): future-proofing key management for post-fault-tolerant era
7	Q&A and Action Planning
