I posted this subject already on Reddit. Here again, hoping to see some more people look into the subject.
One thing I really don’t get is the fact that the same file is encrypted using the same technique and still nobody’s able to link a file to an ip-adress.
Let’s say I join the network. I have 4 close peers based on XOR. When I ask the network for a file, what happends? Do I ask the 4 closest peers (let’s call them my group) for these files? Does any peer in my group receives my request for a file? And if yes… What about a corrupt peer who does exactly what the network expects it to do, but stores the ip-adresses and the chuncks that are requested from the nodes he’s connected to? The corrupt peer will store something like:
64.6768.4657.678 requested chunck: aGjHkljeBjklHikHLjjlhHHjkljhLLL
Now, because all the files are encrypted using the same set of rules, some corrupt peer may look the part up in an index and finds that my chunk with hash: aGjHkljeBjklHikHLjjlhHHjkljhLLL is part of a file called: LinuxMint-17-32bit.iso
So the corrupt peer didn’t behave weird in any way but it sniffed the traffic and found out that I downloaded a part of Linux Mint 17. How is the network protected against this sort of privacy attacks??
And what about populair websites on the network? Websites will become faster because when more people request them. So I’m in China, running Maidsafe and I’m visiting a website about the the “Tankman”. A lot of Chinese people in the network find out about that site so more request them. the Chinese government is sniffing the SAFE-network, it finds the site with the fanous picture of a man in front of a tank. They know the chuncks and hashes which are used. So they create 100 nodes, sniff all the data requests and find out about nodes in China requesting an site about Tankman.
Is ther any way to prevent this? Isn’t it true that using the same self-encryption can safe up to 90% data but creates a weak point in the SAFE-net at the same time??
Really would like to learn about the SAFE-net and how this can be prevented.
