Claim 6:
7. A computer-implemented method, comprising:
receiving, by a registrar computer system associated with a federated network of computing devices, a first request to utilize a shared resource implemented by the federated network of computing devices, the first request provided by a first computing device and including a token associated with the first computing device;
identifying, by the registrar computer system, that the first computing device is an unknown entity based at least in part on the token and one or more signatures used to sign the token and a policy associated with the one or more signatures specified by the registrar computer system, wherein the token includes a canonical address formatting scheme for communicating with the unknown entity residing outside of the federated network of computing devices;
transmitting, by the registrar computer system to a trust management system, a second request to authenticate the first computing device, the second request including the token;
receiving, by the registrar computer system from the trust management system, an authentication message that verifies the first computing device within an open trust network, the authentication message generated by the trust management system in response to the trust management system communicating with a plurality of registrar computers in the open trust network to determine signatures provided by the plurality of registrar computers for the token that represent previous transactions with the first computing device and the token in respective federated networks of computing devices that correspond to the plurality of registrar computers; and
enabling, by the registrar computer to the first computing device, access to the shared resource by at least providing the token and location information for the shared resource to the first computing device, the token signed by the registrar computer and the location information including a network address for communicating with the shared resource.
