Abstract

A second user requests access to a wireless access point, such as a WiFi connection, provided by a first user. To determine whether the first user should be provided with access, the second user identifies a chain of trust relationships between the first and second users. The chain of trust relationships is established by determining if, for example, the first user is in an instant messaging buddy list of the second user, or if there is an intermediate user who both trusts the first user and is trusted by the second user. If a chain of trust relationships between the first and second users exists and is not too attenuated, the second user provides the first user with network access.

Claims

1. A method comprising:

a wireless access point of a first user receiving from a wireless device of a second user a request for access to the wireless access point of the first user;

responsive to the request, the wireless access point of the first user determining whether the second user is in a trust group of the first user;

if the second user is not in a trust group of the first user, then the wireless access point of the first user determining whether there exists a third user such that the second user is in a trust group of the third user and the third user is in the trust group of the first user; and

only if the second user is in a trust group of the first user or is in a trust group of the third user, the wireless access point of the first user providing the second user with access to the wireless access point of the first user in response to the request,

wherein at least one of the trust groups is a buddy list.

2. The method of claim 1, wherein the trust group of the third user is a buddy list, and wherein determining whether the second user is in a trust group of the third user includes querying an instant messaging server to determine whether the second user is a member of the buddy list of the third user.

3. The method of claim 1, wherein the trust group of the first user is a buddy list, and wherein determining whether the second user is in a trust group of the first user includes querying an instant messaging server to determine whether the second user is a member of the buddy list of the first user.

4. The method of claim 1, further comprising the wireless access point of the first user broadcasting an instant messaging address of the first user.

5. The method of claim 1, further comprising the wireless access point of the first user receiving a reference from the second user, wherein the reference identifies the third user.

6. The method of claim 5, further comprising the wireless access point of the first user determining whether the user identified by the reference is in a trust group of the first user.

7. The method of claim 5, further comprising the wireless access point of the first user checking the reference to determine whether the second user is in a trust group of the user identified in the reference.

8. The method of claim 7, wherein checking the reference includes verifying a digital certificate.

9. A method comprising:

a wireless access point of a first user receiving from a wireless device of a second user a request for access to the wireless access point of the first user;

in response to receiving the request for access, the wireless access point of the first user identifying a chain of trust relationships from the second user to the first user via at least a third user;

based at least in part on the chain of trust relationships, the wireless access point of the first user assigning to the second user a level of service; and

in response to receiving the request for access, the wireless access point of the first user providing the second user with access to the wireless access point of the first user in accordance with the assigned level of service,

wherein each trust relationship of the chain of trust relationships comprises being on a buddy list.

10. The method of claim 9, wherein the assigned level of service includes a limitation on amount of access time.

11. The method of claim 9, wherein the assigned level of service includes a limitation on bandwidth.

12. The method of claim 9, wherein the assigned level of service includes a limitation on communication priority.

13. The method of claim 9, further comprising the wireless access point of the first user receiving a reference from the second user, wherein the reference identifies a user having a trust relationship with the second user.

14. The method of claim 13, further comprising the wireless access point of the first user determining whether the first user trusts the user identified by the reference.

15. The method of claim 13, further comprising the wireless access point of the first user checking the reference to determine whether the identified user trusts the second user.

16. The method of claim 9, further comprising the wireless access point of the first user broadcasting an instant messaging address of the first user.

17. A method comprising:

a wireless access point of a first user determining whether a second user seeking access to a wireless access point of a first user is a member of an instant messaging buddy list of the first user; and

the wireless access point of the first user providing the second user access to the wireless access point of the first user only after determining that the second user is a member of the instant messaging buddy list of the first user.
