Abstract

Systems, methods, and instrumentalities are disclosed that may provide for integration of trusted OpenID (TOpenID) with OpenID. The authentication may be accomplished, in part, via communications between a trusted ticket server on a UE and a network application function. The UE may retrieve platform validation data (e.g., from a trusted platform module on the UE). The UE may receive a platform verification in response to the platform validation data. The platform verification may indicate that the network application function has verified the platform validation data and the user. The platform verification may indicate that the platform validation data matches a previously generated reference value.

Claims

1. A method to authenticate a user of a wireless device, the method comprising:

receiving an authentication request from a network application function;

retrieving, by a trusted ticket server, platform validation data, wherein the platform validation data includes a measure of trustworthiness of the wireless device;

sending the platform validation data to the network application function; and

receiving a platform verification indicating that the network application function has verified the platform validation data and the user.

2. The method of claim 1, wherein the platform verification indicates that a system state indicated by the platform validation data matches a previously generated reference value.

3. The method of claim 1, wherein the platform validation data is signed.

4. The method of claim 1, wherein the platform validation data includes a user identification parameter.

5. The method of claim 1, wherein the platform validation data includes attestation data.

6. The method of claim 5, wherein the attestation data includes an SML and a PCR quote signed with an AIK.

7. The method of claim 1, further comprising receiving a ticket comprising the platform verification, wherein the ticket is capable of being reused to perform a subsequent authorization without revalidation of the wireless device.

8. The method of claim 7, wherein the ticket includes a timestamp.

9. The method of claim 7, wherein the ticket includes an origination timestamp.

10. The method of claim 7, wherein the ticket includes a lifetime limit.

11. The method of claim 7, wherein the ticket includes an end date.

12. The method of claim 7, wherein the ticket includes a usage parameter limit.

13. The method of claim 7, further comprising receiving a ticket reference from a network entity.

14. The method of claim 13, wherein the ticket reference is capable of being used to obtain the ticket from a network application function, and wherein the platform verification is capable of being reused to perform a subsequent authorization without revalidation of the wireless device.

15. The method of claim 1, further comprising:

establishing a connection to a relying party;

receiving a browser redirection to the network application function; and

sending an authentication request to the network application function.

16. The method of claim 1, wherein the platform verification includes being granted access to a relying party.
