Abstract:

Recently, operators of public transportation in many countries started
to roll out electronic tickets (e-tickets). E-tickets offer several
advantages to transit enterprises as well as to their customers, e.g.,
they aggravate forgeries by cryptographic means whereas customers
benefit from fast and convenient verification of tickets or replacement
of lost ones.
Existing (proprietary) e-ticket systems deployed in practice are mainly
based on RFID technologies where RFID tags prove authorization by
releasing spatio-temporal data that discloses customer-related data, in
particular their location. Moreover, available literature on
privacy-preserving RFID-based protocols lack practicability for real
world scenarios. In this paper, we discuss appropriate security and
privacy requirements for e-tickets and point out the shortcomings of
existing proposals. We then propose solutions for practical
privacy-preserving e-tickets based on known cryptographic techniques and
RFID technology.
