In systems that use the Extensible Messaging and Presence Protocol (XMPP) [RFC6120], it is important to establish a strong association between the DNS domain name of an XMPP service (e.g., and the XML stream that a client or peer server initiates with that service. In other words, the client or peer server needs to verify the identity of the server to which it connects. Additionally, servers need to verify incoming connections from other servers.

   This document improves the security of the Extensible Messaging and    Presence Protocol (XMPP) in two ways.  First, it specifies how to    establish a strong association between a domain name and an XML    stream, using the concept of "prooftypes".  Second, it describes how    to securely delegate a service domain name (e.g., to a    target server hostname (e.g.,; this is    especially important in multi-tenanted environments where the same    target server hosts a large number of domains.
