[Khasnabish89] Bhumip Khasnabish, A Bound of Deception in Multiuser Computer Networks, IEEE Journal on Selected Areas in Communications 7, no. 4 (May 1989). [This paper describes mathematical limitations on the corruption of information in information systems of specific types. As most such papers, the assumptions in this one lead to conclusions of limited value to general purpose systems in widespread use today; however, such bounds are useful in evaluating other systems.]
