The SCION Book goes over a lot of potential solutions that are possible because of the architecture, but my favorite is hidden paths. https://scion.docs.anapaya.net/en/latest/hidden-paths.html https://scion.docs.anapaya.net/en/latest/hidden-paths.html > Hidden path communication enables the hiding of specific path segments, i.e. certain path segments are only available for authorized ASes. In the common case, path segments are publicly available to any network entity. They are fetched from the control service and used to construct forwarding paths.
