Efforts in quantum safe communication to realize communication security based on physical properties rather than on computational complexity have led to development of both hardware and protocols for quantum key distribution. Further progress is devoted to realization of quantum secure networks and protocols for handling network security of multiple users. In this work, certification method for guaranteeing security on an entangled-based network is pushed forward by implementation of a bilocal network configuration. We are testing so-called full network nonlocality and for the first time go beyond ordinary entanglement swapping protocol to achieve quantum correlations to disprove Bell-like inequality of a full network model.
