Also the HTL18 requests that new nodes do receive will be more specific to their location, so they might be distinguishable from their local requests. Thoughts: - Initial random routing could solve that problem (see https://github.com/freenet/fred/pull/529 ), but initial random routing actually makes correlation attacks easier, because it removes the requirement to know the FOAFs to do the statistics. Knowing all the CHKs for a given file would be a more powerful attack. - Reducing the probability to decrement HTL18 could increase the cover traffic again — 75% to forward HTL18 unchanged would balance this change. To avoid increasing the average distance from senders, that might require reducing Node.canWriteDatastoreRequest to maxHTL - 1, and Node.canWriteDatastoreInsert to maxHTL - 2. - The impact is limited, because our peers route by our FOAFs, and since we’re most likely already close to their location.
