Abstract: A software-defined network (SDN) controller and its method for authenticating switches through encryption of the switches' identifiers. The authenticating method may include obtaining a data path identifier (DPID)-based authentication code, authenticating a received and encrypted session key by using the DPID-based authentication code, determining the presence of another switch having an identical DPID as that of the authenticated switch, and adding a modifier to the DPID and storing the modified DPID if indeed there is another switch with an identical DPID present.
