Abstract
Aspects of the present disclosure involve systems and methods for utilizing verified autonomous system (AS) network interconnections received via a cryptographically certified Recognized Operating Agency (ROA) object to generate an interconnect network model which may be used as a reference model to mitigate hijacking of network communications in downstream route announcements. In particular, AS networks may announce or share a cryptographically certified ROA object that includes a list of other AS networks to which the announcing network is connected. A router, server, or other networking device may receive ROA objects from multiple AS networks and generate a model or graph of the interconnectedness of the AS networks. Further, because each ROA object may be cryptographically certified or signed, the networking device may trust the information provided in the received ROA objects. The networking device may further verify announced routing information against the generated network model.
