Abstract

Techniques for registration of peer-to-peer (P2P) services are provided. A first principal registers a P2P service with a network service provider. The first principal supplies a criterion for granting access to the P2P service. The network service provider distributes an access token to a second principal if the criterion is met. The second principal connects to the P2P service of the first principal via a P2P connection if the second principal successfully acquires the access token from the network service provider.

Claims

1. A method, comprising:

processing a registration for a peer-to-peer (P2P) service from a first principal, wherein the registration includes a criterion for accessing the P2P service; and

determining that a second principal conforms to the criterion and in response thereto supplying an access token to the second principal for securely accessing the P2P service of the first principal over a P2P network connection.

2. The method of claim 1, wherein determining further includes recognizing an identifier that specifically references the second principal within the criterion.

3. The method of claim 1, wherein determining further includes recognizing attributes in the criterion that are possessed or provided by the second principal.

4. The method of claim 1 further comprising, authenticating the second principal before determining that the second principal conforms to the criterion.

5. The method of claim 1 further comprising, embedding dynamic constraints in the token supplied to the second principal, wherein the dynamic constraints are evaluated by the P2P service when the second principal attempts to access the P2P service.

6. The method of claim 1 further comprising, representing the token as an assertion that is recognized and relied upon by the P2P service when presented by the second principal.

7. The method of claim 1, wherein processing further includes authenticating the first principal for authority to register the P2P service in response to the first principal being recognized as having logged into and been authenticated with a different network service provider.

8. A method, comprising:

receiving an access request from a first principal over a peer-to-peer (P2P) network connection;

inspecting the request to determine if an access token is present; and

permitting P2P access to the first principal if the access token is present.

9. The method of claim 8 further comprising, dynamically verifying attributes defined in the access token.

10. The method of claim 9 further comprising, dynamically terminating P2P access if the attributes cannot be verified.

11. The method of claim 8 further comprising, recognizing the access token as an assertion from a network provider service.

12. The method of claim 8 further comprising, terminating P2P access if the first principal violates a policy.

13. The method of claim 12 further comprising, identifying the policy as a component of the access token.

14. The method of claim 12 further comprising, identifying the policy from a policy store in response to an identifier associated with the second principal.

15. A system, comprising:

a peer-to-peer (P2P) service; and

a network service provider, wherein the network service provider is to manage a registration for the P2P service on behalf of a first principal and the network service provider is to selectively distribute an access token to a second principal for access to the P2P service.

16. The system of claim 15, wherein the network service provider is to authenticate the second principal for access to the network service provider service.

17. The system of claim 15, wherein the network service provider is to acquire a list of identifiers that identifies the second principal during the registration of the P2P service.

18. The system of claim 15, wherein the network service provider is to acquire a list of attributes during the registration of the P2P service, and wherein the network service provider is to dynamically determine if the second principal has the attributes before distributing the access token.

19. The system of claim 15, wherein the access token is used by another second version of the P2P service that is to process on a client of the second principal, the second version and the P2P service interact directly with one another over a P2P network.

20. The system of claim 15, wherein the P2P service processes on a client of the first principal and is identified to the network service provider via the registration.

21. A system, comprising:

a first peer-to-peer (P2P) service; and

a second P2P service, wherein the first P2P service processes on a first client of a first principal and is registered with a network service provider, and wherein a registration includes access limitations that are managed by the network service provider, and wherein the second P2P service processes on a second client of a second principal and is to gain P2P access to the first P2P service by acquiring an access token from the network service provider that conforms to the access limitations.

22. The system of claim 21, wherein the access limitations are at least partially embedded in the access token and dynamically resolved by the first P2P service when the second P2P service attempts access to the first P2P service.

23. The system of claim 21, wherein the access token is represented as a signed assertion from the network service provider that the second principal conforms to the access limitations and wherein the first P2P service relies on the signed assertion to provide access to the second P2P service.

24. The system of claim 21, wherein the network service provider is to authenticate the second principal before determining if the second principal conforms to the access limitations.

25. The system of claim 21, wherein the access token permits the second P2P service to access the first P2P service in a secure fashion that is authorized by the first principal, and wherein access is via a P2P network connection.

26. The system of claim 21, wherein the first principal logs into the network service provider via a different network service provider associated with the first principal and trusted by the network service provider.
