Abstract

A method and an apparatus for secure registration for a multicast-broadcast-multimedia system (MBMS) are disclosed. A random number is generated by a broadcast-multicast-service center (BM-SC) and broadcast to user equipment in the coverage area of a radio access network (RAN). A memory module or smart card (UICC) in the user equipment generates a radio access network key (RAK) which is a function of the random number and a key selected from the group consisting of a public land mobile network key (PK) and a broadcast access key (BAK), and then generates a temporary registration key (RGK) as a function of the RAK, a service identification number and a user identification number, for example, P-TMSI, which may be extracted by the RAN to authenticate the registration as legitimate.

1. A method of obtaining secure registration by a memory module (UICC) in a multicast-broadcast-multimedia system (MBMS), the method comprising:

receiving a random number;

generating a radio access network key (RAK) as a function of the random number and a key selected from the group consisting of a public land mobile network key (PK) and a broadcast access key (BAK);

generating temporary registration key (RGK) as a function of the RAK and a user identification number; and

authenticating at least one registration message in the MBMS based on the RGK, wherein the RGK is a function of the RAK, a service identification number and the user identification number.

2. The method of claim 1 , further comprising transmitting the RGK to a mobile telephone.

3. The method of claim 1 , further comprising receiving a provisioning message from a broadcast-multicast service center.

4. The method of claim 3 , wherein the provisioning message is a fraction of the PK and a permanent registration key (RK).

5. The method of claim 3 , further comprising extracting the PK from the provisioning message.

6. The method of claim 1 , wherein the RGK is a function of the RAK and a cyclic redundancy code (CRC) computed from the service identification number and the user identification number.

7. The method of claim 1 , wherein the UICC comprises a subscriber identity module (SIM) in a Global System for Mobile communication (GSM).

8. The method of claim 1 , wherein the UICC comprises a removable user identity module (RUIM) in a code division multiple access (CDMA) system.

9. The method of claim 1 , wherein the PK is provisioned by using a public key.

10. The method of claim 1 , wherein the BAK is provisioned by using a public key.

11. A method of obtaining secure registration by a mobile station in a multicast-broadcast-multimedia system (MBMS), the method comprising:

receiving a random number from a radio access network;

transmitting the random number to a memory module (UICC);

receiving from the UICC a temporary registration key (RGK) based on the random number and a user identification number; and

authenticating at least one registration message in the MBMS based on the RGK, wherein the RGK is a function of a radio access network key (RAK), a service identification number and a user identification number, and wherein the RAK is a function of the random number and a key selected from the group consisting of a public land mobile network key (PK) and a broadcast access key (BAK).

12. The method of claim 11 wherein the PK is extracted from a provisioning message received from a broadcast-multicast service center.

13. The method of claim 12 , wherein the provisioning message is a function of the PK and a permanent registration key (RK).

14. The method of claim 11 , wherein the RGK is a function of the RAK and a cyclic redundancy code (CRC) computed from the service identification number and the user identification number.

16. The method of claim 11 , wherein the UICC comprises a removable user identity module (RUIM) in a code division multiple access (CDMA) system.

17. The method of claim 11 , wherein the PK is provisioned by using a public key.

18. The method of claim 11 , wherein the BAR is provisioned by using a public key.

19. A memory module stored on a computer readable storage medium, comprising:

receiving logic configured for receiving a random number;

means for generating a radio access network key (RAK) as a function of the random number and a key selected from the group consisting of a public land mobile network key (PK) and a broadcast access key (BAK);

means for authenticating at least one registration message in the MBMS based on the RGK, wherein the RGK is a function of the RGK, service identification number and the user identification number.

20. The memory module of claim 19 , further comprising means for transmitting the RGK to a mobile telephone.

21. The memory module of claim 19 , further comprising means for receiving a provisioning message from a broadcast-multicast service center.

22. The memory module of claim 21 , wherein the provisioning message is a function of the PK and a permanent registration key (RK).

23. The memory module of claim 21 , further comprising means for extracting the PK from the provisioning message.

24. The memory module of claim 19 , wherein the RGK is a function of the RAK and a cyclic redundancy code (CRC) computed from the service identification number and the user identification number.

25. The memory module of claim 19 , wherein the PK is provisioned by using a public key.
