Recently, operators of public transportation in many coun- tries started to roll out electronic tickets (e-tickets). E-tickets oer 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 re- leasing spatio-temporal data that discloses customer-related data, in par- ticular 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. |
