If someone owns both they can perform a bit of timing analysis and figure out who you are and where you're going. See this thread http://archives.seul.org/or/talk/Dec-2006/msg00002.html particularly this mail http://archives.seul.org/or/talk/Dec-2006/msg00007.html for what can happen if the same guy owns all three nodes. > If the connection between me and the entry guard is encrypted, and all > I'm telling the entry guard is "please pass this encrypted stream to > next specified tor server", what is the danger?
