They cannot tell if you've got the book, or even if it passed through your computer on the way to somebody else.ĭ, e: Maybe.

if computer "A" transfers data to computer "B", and computer "B" then transfers data to computer "C", an observer cannot tell if that was a download by "B" and an upload by "B", a transfer transiting through "B", a download by "B" and a request being fulfilled by "B"'s cache, an upload by "Q" that happened to wind up in "C" after passing through "A" and "B", or any of a number of other scenarios).Ī, b, and c: No. The network protocol is designed such that an observer cannot tell the difference between a block being transferred as part of an upload and a block being transferred as part of a download, and cannot trace a block through multiple hops (ie. Routing within the network is by peer-to-peer relaying: a data block might pass through dozens of systems (some of which will cache it) on the way to its destination. The data is broken up into blocks, the blocks are encrypted and tagged, and the encrypted blocks are pushed to other systems participating in the network. "Insertion" of data into that data store involves generating a "key" (more or less the "URL" for the data), from which encryption keys and block tags are derived. I'm uploading a banned book instead of downloading it.įreenet is essentially a distributed encrypted data store. Suppose the same adversaries as above (a through e) but this time. If they can find my physical address and suspect I have the book, they'll just send someone to steal my computer, then they'll know. They have money, proxies, botnets, they aren't risk adverse, etc. Presume that I'm probably uninteresting to them, BUT, they are the ones that "banned" the book! (So, they do care about this content, in this hypothetical.) They can see 40% of all Freenet packets, and the memory content of 2% of Freenet machines (not including mine).Į. Some nation-state security type organization (basically NSA). But, he's just one guy who is neither rich nor crazy. He may run several nodes of his own and even use sockpuppetry to suggest weak configuration to other users.
He doesn't have any special access to my network, but he knows Freenet inside and out. A longtime Freenet developer and elite hacker. She can see all packets to and from all the ISP's customers (which includes 5% of all Freenet nodes).Ĭ. A high level network administrator at my ISP, a national cable company. Someone who could see that stuff can just do ls /home/dave/books.)ī. (He can't see my screen nor memory nor file contents-neither can anyone else in this list. He can see all packets I transmit or receive on my network interface. May I download it to local storage without the following groups knowing that I now have a copy?Ī. Suppose there is a banned book stored on Freenet. Of course, I must elaborate on what I mean by "secure".
