METHOD FOR COMMUNICATING IN A NETWORK COMPRISING A VIRTUAL NETWORK, AND A COMMUNICATION NODE COMPRISING A VIRTUAL NETWORK ENTITY

摘要

The invention relates to a method of a communication node communicating in a network comprising a plurality of nodes, said nodes belonging to at least one virtual network, wherein the method comprises the communication node identifying whether a first data packet belongs to said virtual network based on at least one of: - a cryptographic key used for the data packet; - a cryptographic key identifier present in the first data packet; - a Personal Area Network identifier present in the first data packet; or the combination of a cryptographic key and a sender IP address used for the first data packet.
