Even if you have encrypted your traffic with a VPN (or the Tor Network), advanced traffic analysis is a growing threat against your privacy. Therefore, we now introduce DAITA.
Through constant packet sizes, random background traffic and data pattern distortion we are taking the first step in our battle against sophisticated traffic analysis.
I love these guys. Let’s see if somebody can just bootstrap the FOSS framework directly on TCP to work on the internet without a VPN. Fantastic project
I’m afraid just generating random traffic from your IP address won’t do anything against traffic flow analysis. Because most internet traffic is point to point, people who are interested in the flow, just follow the traffic moving between various points. So if you’re sending extra traffic to other random sites, it doesn’t interfere with point-to-point flow analysis.
In the context of a VPN, because all of your traffic is encrypted, you have to work harder to determine what traffic is going where. Because all traffic is going from your network to another virtual network. So an outside observer just sees the size and frequency of traffic but not the destinations. In this context since they don’t see the destinations, it makes sense to add random traffic flows, because that’ll obscure the signal that the observers are looking for.
Considering that VPNs are Point-to-point too (home->VPN), I was wondering if one could use DAITA with TCP directly instead of having to use a VPN. Imagine if TCP had DAITA baked in.
Even if you baked in variable packet size into TCP. It would be trivial for anybody monitoring network flow, to see you who you’re talking to. There would be no ambiguity.
The only reason this makes sense for a VPN, is there’s a lot of traffic bundled together, so a third party doesn’t actually know where your traffic flow is going.
Consider the example if you ran your own personal VPN endpoint. So you were the only user on the VPN. Even with randomized traffic flow injected into your VPN connection, it would be trivial for any third party who’s monitoring traffic flow to know that traffic is yours. Because you’re the only VPN connection talking to the VPN server. This thought experiment applies when you don’t have a VPN at all.
Bootstrapping See the Application section specifically.
FOSS = Free/Open Source Software TCP = Transmission Control Protocol VPN = Virtual Private Network
These words mean a lot actually. Pretty basic terms when it comes to the internet.
Yes, the individual words have meanings, as words tend to do. Those words, in that order, form a NCIS, two people typing on the same keyboard, level word salad that has so little real world relevance that it tips soundly into the absurd.
