摘要: The present invention relates to a method of performing quantum key distribution across network, in particular between first node (202a) and destination (202b) connected via at least one intermediate (204). involves the agreeing key, i.e. cryptographic derived by QKD with path (204) using any known technique. Next exchanges signal, for instance series suitably randomly modulated signal photons, next - which is termed targeted node. communicates previous established details sent or received then performs agreement step agree directly In this way involved authentication avoid man middle type attacks. Having current can be repeated but network as until reached. final agreed used encrypting communication those nodes network.
