Just in time trust establishment and propagation
View Patent ↗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.
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:
establishing a trust relationship directly between a first master server of a first domain in an online service system and a second master server of a second domain in the online service system, wherein the trust relationship is established between public key infrastructures of different domains, and wherein the first master server manages components in the first domain and the second master server manages components in the second domain;
receiving a certificate, by a first computer system in the first domain in the online service system under management of the first master server, of a second computer system in the second domain in the online service system under management of the second master server;
attempting to validate the certificate, by the first computer system in the first domain;
determining, by the first computer system, that a trust relationship does not exist between the first computer system in the first domain and the second computer system in the second domain;
responsive to determining that a trust relationship does not exist between the first computer system in the first domain and the second computer system in the second domain, determining, by the first computer system, whether a trust relationship exists between the first master server of the first domain and the second master server of the second domain, based on an inquiry to a public key infrastructure system of the master server of the first domain;
propagating, by the first computer system, a trust status between the first domain and the second domain to the first computer system in 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 master server of the first domain and the second master server of 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, 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.
7. 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.
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 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.
9. 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.
