Abstract:
Increasingly, automatic restoration is an indispensable security measure in control systems (e.g. those used in
critical infrastructure sectors) due to the importance of ensuring the functionality of monitoring infrastructures.
Modernizing the interconnection of control systems to provide interoperability between different networks, at
a low cost, is also a critical requirement in control systems. However, automated recovery mechanisms are
currently costly, and ensuring interoperability particularly at a low cost remains a topic of scientific challenge.
This is the gap we seek to address in this paper. More specifically, we propose a restoration model for interconnected
contexts, taking into account the theory of supernode and structural controllability, as well as the
recommendations given by the IEC-62351-8 standard (which are mainly based on the implementation of a
role-based access control system).
