As the backbone routing system of the Internet, the operational aspect of the interdomain routing is highly complex. Building a trustworthy ecosystem for interdomain routing requires the proper maintenance of trust relationships among tens of thousands of peer IP domains called Autonomous Systems (ASes). ASes today implicitly trust any routing information received from other ASes as part of Border Gateway Protocol (BGP) updates. Such blind trust is problematic given the dramatic rise in the number of anomalous updates being disseminated, which pose grave security consequences for the interdomain routing operation.
