FYI, at MobiCom '95, an ACM sponsored conference, an interesting paper entitled, _Untraceability in Mobile Networks_, was presented. The authors of the paper are Didier Samfat, Refik Molva and N. Asokan.
The same authors presented papers on similar themes at MCSA `94 (Workshop on Mobile Computing Systems and Applications). See <a href="http://snapple.cs.washington.edu/mobile/mcsa94.html>the MCSA `94 home page</a>, which has links to PostScript versions of the papers. They even had a panel on "Privacy & Anonymity", apparently ! The relevant papers are: Anonymity in a Mobile Computing Environment N. Asokan - University of Waterloo. A Method Providing Identity Privacy to Mobile Users during Authentication Didier Samfat and Refik Molva - Institut Eurecom. On Travelling Incognito A. Herzberg, H. Krawczyk - IBM T.J. Watson, and G.
