  • Patent number: 12007910
    Abstract: A caching sub-system downloads and authenticates Resource Public Key Infrastructure (RPKI) cryptographically signed Route Origin Authorizations (ROAs) from a plurality of repositories, forming a VRP set for each repository. When the caching sub-system determines that the VRP count of a VRP set drops to or below a threshold, it substitutes in a last known valid VRP set. A route validating sub-system downloads route information data from one or more global routing tables and calculates the number of valid routes, the number of unknown routes and the number of invalid routes. When the number of valid routes drops to or below a threshold, the route validating sub-system sets an alarm to stop the distribution of VRPs to one or more group of pre-determined routers.
