5. System design

Securing an embedded telecommunications system (in the sense of being able to withstand partial destruction of nodes or links) depends on whether or not you want to use commercial standards.

The physical layer may be specific, as in the case of the Charles-de-Gaulle aircraft carrier. We can then implement network reconfiguration algorithms that guarantee the resumption of all established communications in less than 50 ms, and design "multi-loop" architectures specially adapted to the problem at hand.
