On-board TM/TC link security approaches currently implemented are reviewed in order to derive reference architectures featuring a security handling function. From this reference, the Security Engineering Process is analysed, i.e. a process that aims at protecting the system development, and not the system itself, against aggressions, and recommendations are proposed.
These guidelines are complemented by detailed recommendations for the management of security services: functional (keys management) and non-functional (FDIR). The current security key management approaches are analysed, and possible short-term and longer-term improvements are proposed. Failures and attacks scenarios that can potentially compromise cryptographic capabilities of a satellite are analysed, identifying the most appropriate redundancy schemes and FDIR procedures and techniques for security units.
