Maybe we need encryption that also plays with the length of the message / or randomly pad our date before encryption ? I am however no expert, so I have no clue

Maybe we need encryption that also plays with the length of the message / or randomly pad our date before encryption ? I am however no expert, so I have no clue how feasible, or full of holes this method would be .
- cvwright 10y agoYes, this is one option that we proposed back in 2009 after we first pointed out the VoIP traffic analysis attacks in 07 and 08. If you want more information, see our paper on traffic morphing from NDSS 2009 [1]. It works pretty well for VoIP; not as great for trying to counter similar attacks on web browsing traffic.
