Zusammenfassung:	Devices and methods are provided for securing communication between a traffic management center (TMC) and a traffic controller via utilization of a field security device. In one embodiment, the field security device transmits a device identifier to the TMC upon being powered up or connected to the traffic controller. The device identifier is generally based on a combination of user-configurable and non-user-configurable parameters of the field security device. In response to the TMC authenticating the device identifier, the field security device establishes a secure private network (SPN) between the field security device and the TMC.
