Abstract

Trust relationships in an online service system are established at a domain level, and propagated to components of domains as they attempt cross domain communication. In attempting to communicate across domains, a first component in a first domain attempts to validate a certificate of a second component in a second domain. Where the attempt to validate the certificate indicates that a trust relationship does not exist between the first component and the second domain, the first component determines whether a domain level trust relationship exists between the two domains. The first component propagates the trust status between the first and second domains to itself. If there is an existing trust relationship between the first and second domains, the first component validates the certificate of the second component in response. The second component executes the same process to complete the connection.

Claims

1. A computer implemented method for propagating trust relationships between components across multiple domains in at least one online service system, the method comprising the steps of:

attempting to validate, by a first computer system in a first domain of an online service system, a certificate of a second computer system in a second domain of an online service system;

3. The method of claim 1 wherein determining, by the first computer system, whether a trust relationship exists between the first domain and the second domain further comprises:

determining, by the first computer system, whether a trust relationship exists between a public key infrastructure system of the first domain and a public key infrastructure system of the second domain.

4. The method of claim 1 wherein determining, by the first computer system, whether a trust relationship exists between the first domain and the second domain further comprises:

receiving, by the first computer system, trust relationships of a public key infrastructure system of the first domain; and

determining whether a trust relationship with the second domain is among the received trust relationships of the public key infrastructure system of the first domain.

5. The method of claim 1 wherein determining, by the first computer system, whether a trust relationship exists between the first domain and the second domain further comprises:

querying, by the first computer system, a public key infrastructure system of the first domain as to whether it has a trust relationship with the second domain.

6. The method of claim 1 wherein propagating, by the first computer system, the trust status between the first domain and the second domain to the first computer system in the first domain further comprises:

receiving, by the first computer system, trust relationships of a public key infrastructure system of the first domain; and

extending, by the first computer system, the received trust relationships of the public key infrastructure system of the first domain to the first computer system in the first domain.

7. The method of claim 1 wherein propagating, by the first computer system, the trust status between the first domain and the second domain to the first computer system in the first domain further comprises:

receiving, by the first computer system, an indication from a public key infrastructure system of the first domain that the public key infrastructure system of the first domain has a trust relationship with the second domain; and

extending, by the first computer system, the trust relationship of the public key infrastructure system of the first domain with the second domain to the first computer system in the first domain.

8. The method of claim 1 wherein determining, by the first computer system, whether to validate the certificate of the second computer system responsive to the propagated trust status further comprises:

responsive to extending a trust relationship of a public key infrastructure system of the first domain with the second domain to the first computer system in the first domain, validating, by the first computer in the first domain, the certificate of the second computer system in the second domain.

9. The method of claim 1 wherein determining, by the first computer system, whether to validate the certificate of the second computer system responsive to the propagated trust status further comprises:

responsive to not detecting a trust relationship of a public key infrastructure system of the first domain with the second domain, not validating, by the first computer in the first domain, the certificate of the second computer system in the second domain.

10. The method of claim 1 wherein:

the first domain is of a first online service system and the second domain is of a second online service system.

11. At least one computer readable storage medium storing a computer program product for propagating trust relationships between components across multiple domains in at least one online service system, the computer program product comprising:
