Abstract

A method is provided for provisioning a device certificate. A device certificate request is transmitted from a communication device to a server in a communication network using an established communications channel between the communication device and the server. The device certificate request comprises at least a user identifier and a device identifier. The server provides to the communication device a device certificate that includes the user identifier and the device identifier and that is signed by a private key of a certificate authority.

Claims

1. A method at a communication device for provisioning a device certificate, the method comprising:

transmitting a device certificate request to a server in a communication network using an established communications channel between the communication device and the server, wherein the device certificate request comprises at least a user identifier and a device identifier; and

responsive to transmitting the device certificate request, receiving a device certificate that includes the user identifier and the device identifier and that is signed by a private key of a certification authority.

2. The method as recited in claim 1, further comprising:

enabling user input of the user identifier at the communication device.

3. The method as recited in claim 1, wherein the device certificate request is transmitted to the server in a communication that is encrypted with a master communication key established between the server and the communication device.

4. The method as recited in claim 3, wherein the device certificate is received from the server in a communication that is encrypted with the master communication key.

5. The method as recited in claim 1, wherein the server acts as the certification authority.

6. The method as recited in claim 1, wherein the certification authority is a third party certification authority.

7. The method as recited in claim 1, wherein the user identifier is associated with a person and comprises one or more of the following:

a number assigned by a government agency to the person, an identification of an employer of the person, a name or address or both of the person, a telephone number of the person.

8. The method as recited in claim 1, wherein the device identifier comprises one or more of the following:

a device personal identification number, a device serial number, and a device International Mobile Subscriber Identity (IMSI).

9. A method at a server in a communication network, the method comprising:

receiving a device certificate request from a communication device over an established communications channel between the communication device and the server, wherein the device certificate request comprises at least a user identifier and a device identifier; and

responsive to receiving the device certificate request, providing to the communication device a device certificate that includes the user identifier and the device identifier and that is signed by a private key of a certification authority.

10. The method as recited in claim 9, wherein the device certificate request is received by the server in a communication that is encrypted with a master communication key established between the server and the communication device.

11. The method as recited in claim 10, wherein the device certificate is provided to the communication device by the server in a communication that is encrypted with the master communication key.

12. The method as recited in claim 9, wherein the server acts as the certification authority.

13. The method as recited in claim 9, wherein the certification authority is a third party certification authority.

14. The method as recited in claim 9, wherein the user identifier is associated with a person and comprises one or more of the following:

a number assigned by a government agency to the person, an identification of an employer of the person, a name or address or both of the person, a telephone number of the person.

15. The method as recited in claim 9, wherein the device identifier comprises one or more of the following:

a device personal identification number, a device serial number, and a device International Mobile Subscriber Identity (IMSI).

16. A communication device configured:

to establish a master communication key with a server in a communication network for encryption and decryption of communication with the server;

to transmit a device certificate request to a server in a communication network using an established communications channel between the communication device and the server, wherein the device certificate request comprises at least a user identifier and a device identifier; and

responsive to transmitting the device certificate request, to receive a device certificate that includes the user identifier and the device identifier and that is signed by a private key of a certification authority.

17. The communication device as recited in claim 16, further configured to:

enable user input of the user identifier at the communication device.

18. The communication device as recited in claim 16, wherein the device certificate request is transmitted to the server in a communication that is encrypted with a master communication key established between the server and the communication device.

19. The communication device as recited in claim 18, wherein the device certificate is received from the server in a communication that is encrypted with the master communication key.

20. The communication device as recited in claim 16, wherein the server acts as the certification authority.

21. The communication device as recited in claim 16, wherein the certification authority is a third party certification authority.

22. The communication device as recited in claim 16, wherein the user identifier is associated with a person and comprises one or more of the following:

a number assigned by a government agency to the person, an identification of an employer of the person, a name or address or both of the person, a telephone number of the person.

23. The communication device as recited in claim 16, wherein the device identifier comprises one or more of the following:

a device personal identification number, a device serial number, and a device International Mobile Subscriber Identity (IMSI).

24. A server configured:

to receive a device certificate request from a communication device over an established communications channel between the communication device and the server, wherein the device certificate request comprises at least a user identifier and a device identifier; and

responsive to receiving the device certificate request, to provide to the communication device a device certificate that includes the user identifier and the device identifier and that is signed by a private key of a certification authority.

25. The server as recited in claim 24, wherein the device certificate request is received by the server in a communication that is encrypted with a master communication key established between the server and the communication device.

26. The server as recited in claim 25, wherein the device certificate is provided to the communication device by the server in a communication that is encrypted with the master communication key.

27. The server as recited in claim 24, wherein the server acts as the certification authority.

28. The server as recited in claim 24, wherein the certification authority is a third party certification authority.

29. The server as recited in claim 24, wherein the user identifier is associated with a person and comprises one or more of the following:

a number assigned by a government agency to the person, an identification of an employer of the person, a name or address or both of the person, a telephone number of the person.

30. The server as recited in claim 24, wherein the device identifier comprises one or more of the following:

a device personal identification number, a device serial number, and a device International Mobile Subscriber Identity (IMSI).
