Correct.<br>
<br>
Pluggable Transports are (normally) used for hiding that one is speaking the<br>
Tor protocol (also they could be used to disguise any protocol). [0] A middle<br>
relay, or any normal non-bridge relay, is listed in the consensus, meaning<br>
that anyone who looks at the consensus already knows you're speaking Tor.<br>
<br>
All of that said, scramblesuit and obfs4 both have some interesting<br>
protections against traffic fingerprinting via timing correlations and packet<br>
size distributions, meaning that (if there were a way to do this) relays could<br>
use PTs between them to protect against some correlations. Doing this would be<br>
super weird. No one has done yet, to my knowledge, a security analysis of how<br>
running PTs in between normal relays would change things. That analysis would<br>
be really interesting.<br>

     for visual explanation of how some of the different PTs change your<br>
     traffic.<br>
