To protect user data and privacy, Internet transport protocols have
supported payload encryption and authentication for some time. Such
encryption and authentication are now also starting to be applied to
the transport protocol headers. This helps avoid transport protocol
ossification by middleboxes, mitigate attacks against the transport
protocol, and protect metadata about the communication. Current
operational practice in some networks inspect transport header
information within the network, but this is no longer possible when
those transport headers are encrypted.
This document discusses the possible impact when network traffic uses
a protocol with an encrypted transport header. It suggests issues to
consider when designing new transport protocols or features.
