Because there has been already packet length used for messaging so often that even its detection has been discussed in papers, this cannot be very novel. However, often the use of such side-channel is used ...

It makes perfect sense to use Diffie-Hellman/RSA, yet someone up there decided to standardize it in a non optimal way. The world is inefficient and standards move slower than mountains, numerous ...
