It seems to be <!-- small random string with random length --> in html sent by server, will be useful to protect from this attack. Length of response will be always different, and this difference can't be guessed by attacker.
- lmkg 13y agoLike adding jitter to try and disrupt timing attacks, this increases the cost to the attacker but does not actually prevent the attack. If you send a@gmail.com a couple of times, you will get an average length. No matter how much noise, send it enough times and you can get statistical confidence in the average length. There's also the issue that adding random incompressable junk to your packets sort of defeats the point of compressing them in the first place.
