Obfuscated TCP è un interessante progetto di Adam Langley che propone delle modifiche al protocollo TCP in modo da avere comunicazioni cifrate e firmate:

Attualmente l’implementazione consiste in una serie di patch per il kernel di Linux e in una libreria.

Da leggere il draft con le specifiche (ecco l’abstract):

This document describes an extension to TCP [RFC0793] which permits a small, mostly constant data payload to be carried in the SYN+ACK frame of the 3-way handshake.  This new behaviour is enabled by an option in the SYN packet to ensure backwards compatibility.  We should how this has latency benefits, specifically for cryptographic applications.
