We all know about different encryption methods used today in secured connections like VPN, Tor, etc. However, there is an issue with usage of those. Even if the outsider can not decrypt the message, or establish the exact addresses if it is in onion routing, there is still a possibility to determine, that some IP address is participating in the secret connection, and then it is trivial to discover the physical person behind the IP address.
So is there any method to hide the usage of encrypted connection steganographically, means, the observing outsider will no "even" notice, that a secure connection is established. For example, this connections will pretend to be unsecured http traffic, or unsecured file exchange.
