Title : PKIX over Secure HTTP (POSH)

Abstract:
Experience has shown that it is extremely difficult to deploy proper
PKIX certificates for TLS in multi-tenanted environments, since
certification authorities will not issue certificates for hosted
domains to hosting services, hosted domains do not want hosting
services to hold their private keys, and hosting services wish to
avoid liability for holding those keys. As a result, domains hosted
in multi-tenanted environments often deploy non-HTTP applications
such as email and instant messaging using certificates that identify
the hosting service, not the hosted domain. Such deployments force
end users and peer services to accept a certificate with an improper
identifier, resulting in obvious security implications. This
document defines two methods that make it easier to deploy
certificates for proper server identity checking in non-HTTP
application protocols. The first method enables the TLS client
associated with a user agent or peer application server to obtain the
end-entity certificate of a hosted domain over secure HTTP as an
alternative to standard PKIX techniques. The second method enables a
hosted domain to securely delegate a non-HTTP application to a
hosting service using redirects provided by HTTPS itself or by a
pointer in a file served over HTTPS at the hosted domain.
