Device and Method for Secured Communication
First Claim
1. A field security device for providing a secure private network (SPN) between a field traffic controller and a traffic management center (TMC), comprising:
- a first connector for interfacing with the field traffic controller;
a communication module;
at least one processor operative coupled to the first connector and the communication module; and
a memory module operatively coupled to the at least one processor and comprising executable code for the at least one processor to;
access a public network via the communication module;
locate an authentication server of the TMC via the public network;
send a device identifier to the authentication server via the communication module, the device identifier being based on a combination of at least one user-configurable parameter and at least one non-user-configurable parameter of the field security device; and
in response to the authentication server authenticating the device identifier from the field security device, establish the SPN between the field security device and the TMC, wherein the established SPN tunnels across at least one segment of the public network.

Abstract
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.

17. An authentication server for providing a secure private network (SPN) between a traffic management center (TMC) and a field security device, the field security device being in operative communication with a field traffic controller, comprising:
-
a communication module adapted to receive a device identifier over a public network from the field security device, the device identifier being based on a combination of at least one user-configurable parameter and at least one non-user-configurable parameter of the field security device; at least one processor operatively coupled to the communication module; and a memory module operatively coupled to the at least one processor and comprising executable code for the at least one processor to; in response to the communication module receiving the device identifier from the field security device, access a database of authorized device identifiers corresponding to known field security devices; and in response to the received device identifier matching one of the authorized device identifiers, establish the SPN between the field security device and the TMC, wherein the established SPN tunnels across at least one segment of the public network. - View Dependent Claims (18, 19, 20)
