Abstract: Systems and methods are provided for rules-based routing of a request based on a proxy included in the request. One example computer-implemented method includes receiving, by a first computing device, a proxy lookup request from a proxy requestor, the proxy lookup request including a proxy; based on the proxy and one or more rules indicative of a scheme associated with the proxy, submitting, by the first computing device, the proxy lookup request to a second computing device, in lieu of searching for the proxy in a local directory of the first computing device; receiving, by the first computing device, from the second computing device, a proxy lookup response, which includes account data linked to the proxy; and returning, by the first proxy service core computing device, the proxy lookup response, to the proxy requestor, in response to the proxy lookup request.

Abstract: Systems and methods are provided for aggregate routing in response to requests associated with interconnecting directories. One example computer-implemented method includes receiving, from a participant, a proxy lookup request, the proxy lookup request including a proxy; submitting the proxy lookup request to each of multiple directories; determining that a proxy lookup response has been received from each of the multiple directories; and in response, aggregating the proxy lookup responses into an aggregate proxy lookup response; and returning the aggregate proxy lookup response, to the participant, in response to the proxy lookup request.

Abstract: Systems and methods are provided for interconnecting proxy directories, through core proxy services. One example computer-implemented method includes receiving, by a first proxy service core computing device, from a participant, a proxy lookup request, where the proxy lookup request includes a proxy and based on one or more routing rules, submitting the proxy lookup request to a second proxy service core computing device. The method also includes receiving, by the first proxy service core computing device, from the second proxy service core computing device, a proxy lookup response, which includes account data linked to the proxy, and returning the proxy lookup response, to the participant, in response to the proxy lookup request.

Abstract: Systems and methods are provided for deploying keys in connection with proxy resolution. One example computer-implemented method includes distributing, by a service core computing device, a root certificate signed by a certificate authority and an intermediate certificate, which is signed by a root private key associated with the root certificate, and receiving, from a participant, a signing request for a participant certificate including a participant public key. The method also includes assessing, by the service core computing device, the signing request for the participant certificate and signing, by the service core computing device, the participant certificate with an intermediate public key included in the intermediate certificate. The method then includes disseminating the signed participant certificate to the participant and another participant, whereby the participants on the participant certificate based on the participant certificate being signed by the intermediate public key.
