Many papers on anonymous networks talk about a global passive adversary that has access to the data entering and leaving every node. Very few of the papers that I have read claim their networks are effective against a global passive adversary (GPA). The ones that do claim to be effective, and back that up with some calculations of entropy, are really inefficient. I don't think Tor ever claimed to be effective against a GPA. This paper gives some background: http://mice.cs.columbia.edu/getTechreport.php?techreportID=556&format=pdf& http://mice.cs.columbia.edu/getTechreport.php?techreportID=5...
