BGP Security Solutions

The goal of this comparison is to summarize the efficacy and the operational use of the Border Gateway Protocol (BGP) security solutions. Description of properties: "in use": indicates whether the solution is in operational use, "method": indicates whether the solution is based on a cryptographic protocol or an anomaly detection service, "origin authentication": indicates whether the origin AS is authenticated, "path authentication": indicates whether the AS path is authenticated, "topology authentication": indicates whether the AS paths are conforming to the correct topology. Description of values: A system is considered "strong" if it provides authenticity guarantees and "weak" if the data/methods used are probabilistic.
