Abstract

A one-pass authentication mechanism and system for heterogeneous networks are provided. The mechanism comprises authenticating a user based on an authentication key and an authentication algorithm in response to a request of the user to register a first network, wherein the authentication key and the authentication algorithm are associated with a first user identity for the first network and a second user identity for a second network; and if the authentication is successful, then comparing the first user identity retrieved from an authentication database through the second user identity provided by the user to the first user identity provided by the user in the authentication, in response to a request of the user to register the second network, and setting up security associations between the user and the second network if the retrieved first user identity matches the first user identity provided by the user.

Claims

1. A method of one-pass authentication mechanism for heterogeneous networks, comprising the steps of:

authenticating a user based on an authentication key and an authentication algorithm in response to a request of the user to register a first network, wherein the authentication key and the authentication algorithm are associated with a first user identity for the first network and a second user identity for a second network; and

if the authentication is successful, then

comparing the first user identity retrieved from an authentication database through the second user identity provided by the user to the first user identity provided by the user in the authentication, in response to a request of the user to register the second network, and

setting up security associations between the user and the second network if the retrieved first user identity matches the first user identity provided by the user.

2. The method of claim 1, further comprising the steps of:

intercepting the request of the user to register the second network, wherein the request contains the second user identity provided by the user; and

before forwarding the request, modifying the request by adding the first user identity provided by the user in the authentication.

3. The method of claim 1, wherein the step of authenticating the user based on the authentication key and the authentication algorithm further comprises the steps of:

selecting first authentication parameters for the user;

performing verifications based on the first authentication parameters according to a first authentication agreement between the user and the first network; and

performing a registration procedure of the first network for the user after performing the verifications successfully.

4. The method of claim 3, wherein the first authentication agreement shares the authentication key and the authentication algorithm with a second authentication agreement between the user and the second network.

6. The method of claim 3, further comprising the step of generating the first authentication parameters based on records of the user retrieved from the authentication database through the first user identity provided by the user, wherein the records of the user include at least the authentication key and the authentication algorithm.

7. The method of claim 4, wherein the step of setting up the security associations between the user and the second network is based on second authentication parameters for the user according to the second authentication agreement.

8. The method of claim 7, further comprising the step of generating the second authentication parameters based on records of the user retrieved from the authentication database through the second user identity provided by the user, wherein the records of the user include at least the authentication key and the authentication algorithm.

9. The method of claim 1, wherein the first network is a WiMAX network and the second network is an IP Multimedia Subsystem (IMS) network.

5. (canceled)

10. A one-pass authentication system for heterogeneous networks, comprising:

an authentication database, operable to store a first user identity for a first network, a second user identity for a second network, and an authentication key and an authentication algorithm associated with the first and second user identities;

a first authentication server operable to authenticate a user based on the authentication key and the authentication algorithm in response to a request of the user to register the first network; and

a second authentication server operable to compare the first user identity retrieved from the authentication database through the second user identity provided by the user to the first user identity provided by the user in the authentication, in response to a request of the user to register the second network, and set up security associations between the user and the second network if the retrieved first user identity matches the first user identity provided by the user.

11. The system according to claim 10, further comprising an access gateway connected to the first and second authentication servers, wherein the access gateway is operable to:

intercept the request of the user to register the second network, wherein the request contains the second user identity provided by the user; and

before forwarding the request, modify the request by adding the first user identity provided by the user in the authentication.

12. The system according to claim 10, wherein the first authentication server is further operable to:

select first authentication parameters for the user;

perform verifications based on the first authentication parameters according to a first authentication agreement between the user and the first network; and

perform a registration procedure of the first network for the user after performing the verifications successfully.

13. The system according to claim 12, wherein the first authentication agreement shares the authentication key and the authentication algorithm with a second authentication agreement between the user and the second network.

15. The system according to claim 12, wherein the first authentication server is operable to access the first authentication parameters from the authentication database, and the authentication database is operable to:

retrieve records of the user through the first user identity provided by the user, wherein the records of the user include at least the authentication key and the authentication algorithm; and

generate the first authentication parameters based on the records of the user.

16. The system according to claim 13, wherein the second authentication server is operable to set up the security associations between the user and the second network based on second authentication parameters for the user according to the second authentication agreement.

17. The system according to claim 16, wherein the second authentication server is operable to access the second authentication parameters from the authentication database, and the authentication database is operable to:

retrieve records of the user through the second user identity provided by the user, wherein the records of the user include at least the authentication key and the authentication algorithm; and

generate the second authentication parameters based on the records of the user.
