Abstract

A system for secured communications includes a control center, a network transceiver, an authentication server communicatively coupled between the control center and the network transceiver, and an extended trust device communicatively coupled between the authentication server and a client, the extended trusted device being configured to send a device identifier to the authentication server via the network transceiver, the device identifier being based on a combination of a user-configurable parameter and a non-user-configurable parameter of the extended trust device, wherein the authentication server is configured to determine access privilege of a client to the control center by authenticating the device identifier received from extended trust device.

Claims

1. A secured communication network comprising:

a control center;

a network transceiver;

an authentication server communicatively coupled between the control center and the network transceiver; and

an extended trust device communicatively coupled between the authentication server and a client, the extended trusted device being configured to send a device identifier to the authentication server via the network transceiver, the device identifier being based on a combination of one or more of a user-configurable parameter and a non-user-configurable parameter of the extended trust device;

wherein the authentication server is configured to determine access privilege of a client to the control center by authenticating the device identifier received from extended trust device.

2. The secured communication network of claim 1, wherein the extended trust device is configured to send to the authentication server a client identifier comprising one or more items selected from the list consisting of MAC address of the client, Internet Protocol address of the client, a serial number of the client, a predetermined identification number of the client, a user name, a client name, and a user password.

3. The secured communication network of claim 2, wherein the authentication server is configured to determine access privilege of the client to the control center by authenticating the client identifier.

4. The secured communication network of claim 1, wherein the at least one non-user-configurable parameter is based on a degradation characteristic of a computer chip of the device.

5. The secured communication network of claim 1, wherein the at least one user-configurable parameter comprises one of hard disk volume name, user name, device name, user password, and hard disk initialization date for the device.

6. The secured communication network of claim 1, wherein the device identifier is generated by utilizing at least one irreversible transformation of the at least one user-configurable parameter and the at least one non-user-configurable parameter of the device.

7. The secured communication network of claim 1, wherein the device identifier is generated by utilizing a cryptographic hash function on the at least one user-configurable parameter and the at least one non-user-configurable parameter of the device.

8. The secured communication network of claim 1, wherein the device identifier is generated using by utilizing a cryptographic hash function on the at least one user-configurable parameter and the at least one non-user configurable parameter of the device.

9. A mobile network device for secured communication with at least one static node, comprising:

a transceiver module configured to communicate with the at least one static node and a field device;

at least one processor operatively coupled to the transceiver module; and

a memory module operatively coupled to the at least one processor and comprising executable code, when executed, causes the at least one processor to;

locate the at least one static node via a public network;

send a device identifier to the at least one static node via the transceiver 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 device; and

in response to the at least one static node authenticating the received device identifier, establish a secure private network (SPN) with the at least one static node.

10. The device of claim 9, wherein the memory module further comprising executable code, when executed, causes the at least one processor to send to the static node at least one a MAC address of the client, an Internet Protocol address of the field device, a serial number of the field device, a predetermined identification number of the field device, a user name, a device name, and a user password.

11. The device of claim 9, wherein the at least one non-user-configurable parameter is based on a degradation characteristic of a computer chip of the device.

12. The device of claim 9, wherein the at least one user-configurable parameter comprises one of hard disk volume name, user name, device name, user password, and hard disk initialization date for the device.

13. The device of claim 9, wherein the device identifier is generated by utilizing at least one irreversible transformation of the at least one user-configurable parameter and the at least one non-user-configurable parameter of the device.

14. A method, comprising:

receiving a device identifier at an authenticating server over a public network from an extended trust 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 extended trust device, the authenticating server being communicatively coupled between a secured server and the public network;

accessing a database of authorized device identifiers corresponding to known extended trust devices; and

in response to the received device identifier matching one of the authorized device identifiers, establishing a secure private network (SPN) between the extended trust device and the secured server.

15. The method of claim 14, further comprising receiving a client identifier from the extended trust device, wherein the client is directly coupled to the extended trust device, and wherein the client identifier comprises at least one or more items selected from the list consisting of a MAC address of the client, an Internet Protocol address of the client, a serial number of the client, a predetermined identification number of the client, a user name, a client name, and a user password.

16. The method of claim 15, further comprising determining access privilege of the client to the secured server by authenticating the client identifier.

17. The method of claim 14, wherein the at least one non-user-configurable parameter comprises at least one of CPU ID, CPU model, CPU manufacturer, and CPU voltage for the device.

18. The method of claim 14, wherein the at least one non-user-configurable parameter is based on a degradation characteristic of a computer chip of the device.

19. The method of claim 14, wherein the at least one user-configurable parameter comprises one of hard disk volume name, user name, device name, user password, and hard disk initialization date for the device.

20. The method of claim 14, wherein the device identifier is generated by utilizing at least one irreversible transformation of the at least one user-configurable parameter and the at least one non-user-configurable parameter of the device.
