In particular, we focus on two different solutions that co-exist as part of the overall intelligent network control and management system. On the one hand, the OCATA optical layer network digital twin is presented as a tool that can detect perturbation and variations in optical constellation samples in order to detect and identify attacks on machine learning pipelines compromising secure autonomous network operation. On the other hand, the DARIUS quantum digital twin is presented as a tool that allows improving the behavior of real quantum key distribution (QKD) systems by increasing their key exchange rate while keeping the outstanding ability to detect eavesdropping attacks.
