Abstract--We present the first Internet architecture designed
to provide route control, failure isolation, and explicit trust
information for end-to-end communications. SCION separates
ASes into groups of independent routing sub-planes, called trust
domains, which then interconnect to form complete routes. Trust
domains provide natural isolation of routing failures and human
misconfiguration, give endpoints strong control for both inbound
and outbound traffic, provide meaningful and enforceable trust,
and enable scalable routing updates with high path freshness. As
a result, our architecture provides strong resilience and security
properties as an intrinsic consequence of good design princi-
ples, avoiding piecemeal add-on protocols as security patches.
Meanwhile, SCION only assumes that a few top-tier ISPs in
the trust domain are trusted for providing reliable end-to-end
communications, thus achieving a small Trusted Computing Base.
