Personal Marks and Community Certificates: Detecting Clones in Mobile Wireless Networks of Smart-Phones

This can happen quite easily, because of a virus that immediately after sending all the content of the infected device to the adversary destroys itself, or just because the owner has left his device unattended for a few minutes in a hostile environment. The problem is to detect this attack. They propose a solution in networks of mobile devices carried by individuals.
