Disclosed are systems, apparatuses, methods, and computer-readable media for secure network routing. A method includes: receiving, at a network node, an advertisement message for a network route including an IP address prefix; receiving, at the network node, a route origin authorization associated with the IP address prefix, the route origin authorization including a digital signature and a security requirement of a route to a destination that corresponds to the IP address prefix; determining, by the network node, one or more network nodes satisfies the security requirement to yield a determination; and determining, by the network node, to route network traffic to the IP address prefix based on the determination. In one example, the method can include, when the one or more network nodes satisfies the security requirement, advertising the route to the one or more network nodes that satisfies the security requirement.
