How safe is the OV-chipcard?

In The Netherlands, we can enter the public transport using an electronic
ticket, the so called OV Chipkaart. At Collis we have years of experience
with the Dutch OV Chipkaart and similar systems in many countries, e.g.
Germany, Singapore and New Zealand.
In December 2007 it was shown that the security of chip used for the OV
Chipkaart, the MIFARE Classic chip, could be compromised. During the last
years there has been a lot of media attention for hacking the OV
Chipkaart, and multiple ways to commit fraud have made it to the
headlines.
In this talk we will give insight in the background of the security
issues in the Dutch OV Chipkaart. We will elaborate on the current status
and try to relate the actual issues to the recent reports and articles in
the media. Furthermore, we will discuss potential countermeasures to
prevent fraud in the (near) future.
The presentation will be given by Robert Meppelink. He started to work
for Collis in January 2010, after receiving a PhD from the University of
Utrecht on the subject of “Hydrodynamic excitations in a Bose-Einstein
condensate”.
