Abstract

Systems, methods, and/or techniques for transferring ownership or rolling-over machine-to-machine (M2M) and/or internet of things (IoT) devices from a first owner to a second owner may be disclosed. For example, at a M2M and/or IoT device, a roll-over token and/or a message with the roll-over token may be received. The roll-over token may be configured to be used to transfer ownership and/or update credentials, and/or the roll-over token may be configured to be requested by a first device management server (DMS) associated with the first owner and/or may be generated by a reset server (RS), for example, in response to the request by the first DMS. A validity of the roll-over token may be checked or determined.

Claims (36)

1. A method for transferring control of a machine-to-machine (M2M) device from a first device management server (DMS) to a second DMS, based on authorization from a reset server, the method comprising:

storing, in the M2M device, a reset credential from the reset server for validating a roll-over token generated by the reset server;

receiving, in the M2M device, from the reset server, the roll-over token, wherein the M2M device receives the roll-over token directly from the reset server or from the reset server via the first DMS;

determining, in the M2M device, a validity of the roll-over token based on the stored reset credential, wherein the validity determination includes the M2M device checking a Message Authentication Code (MAC) or a digital signature;

extracting, in the M2M device, from the roll-over token, a uniform resource identifier (URI) for the second DMS;

establishing a connection from the M2M device to the second DMS based on the extracted URI;

storing, in the M2M device, a second DMS credential and deleting a first DMS credential associated with the first DMS; and

establishing a secure connection with the second DMS based on the second DMS credential.

2. The method of claim 1 , wherein the roll-over token is generated by the reset server in response to a request from one of the first DMS and the second DMS.

3. The method of claim 1 , further comprising one of extracting the second DMS credential from the roll-over token and receiving the second DMS credential from the second DMS.

4. The method of claim 1 , wherein the roll-over token comprises a secure key.

5. The method of claim 4 , wherein the secure key comprises symmetric key-based credentials or public key-based credentials.

6. The method of claim 1 , further comprising decrypting the roll-over token.

7. The method of claim 1 , further comprising performing a mutual authentication between the M2M device and the second DMS before establishing a secure connection with the second DMS.

8. The method of claim 7 , further comprising establishing a secure channel with the second DMS based on the first DMS credential before establishing the secure connection with the second DMS.

9. The method of claim 7 , further comprising establishing a secure channel with the second DMS based on a temporary DMS credential before establishing the secure connection with the second DMS.

10. The method of claim 7 , wherein the mutual authentication and secure channel between the second DMS and the M2M device is established based on an M2M device key and a symmetric key.

11. A machine-to-machine (M2M) device that can transfer control of the M2M device from a first device management server (DMS) to a second DMS, based on authorization from a reset server, comprising:

a memory configured to store a reset credential for validation of a roll-over token generated by the reset server;

a processor configured to:

store, in the M2M device, the reset credential, wherein the reset credential is received in the M2M device from the reset server;

receive, in the M2M device, from the reset server, the roll-over token, wherein the M2M device receives the roll-over token directly from the reset server or from the reset server via the first DMS;

determine, in the M2M device, a validity of the roll-over token based on the stored reset credential, wherein the validity determination includes the M2M device checking a Message Authentication Code (MAC) or a digital signature;

extract, in the M2M device, from the roll-over token, a uniform resource identifier (URI) for the second DMS;

establish a connection from the M2M device to the second DMS based on the extracted URI;

store, in the M2M device memory, a second DMS credential and delete a first DMS credential associated with the first DMS; and

establish a secure connection with the second DMS based on the second DMS credential.

12. The M2M device of claim 11 , wherein the received roll-over token was generated by the reset server in response to a request from one of the first DMS and the second DMS.

13. The M2M device of claim 11 , wherein the processor is further configured to either extract the second DMS credential from the roll-over token or receive the second DMS credential from the second DMS.

14. The M2M device of claim 11 , wherein the roll-over token comprises a secure key.

15. The M2M device of claim 14 , wherein the secure key comprises symmetric key-based credentials or public key-based credentials.

16. The M2M device claim 11 , wherein the processor is further configured to decrypt the roll-over token.

17. The M2M device of claim 11 , wherein the processor is further configured to perform a mutual authentication between the M2M device and the second DMS before establishing a secure connection with the second DMS.

18. The M2M device of claim 17 , wherein the processor is further configured to establish the mutual authentication and secure channel between the second DMS and the M2M device based on an M2M device key and a symmetric key.

19. The M2M device of claim 17 , wherein the processor is further configured to establish a secure channel with the second DMS based on the first DMS credential before establishing the secure connection with the second DMS.

20. The M2M device of claim 17 , wherein the processor is further configured to establish a secure channel with the second DMS based on a temporary DMS credential before establishing the secure connection with the second DMS.
