Arnau VIVES-GUASCH †a) , Student Member, Maria-Magdalena PAYERAS-CAPELLÀ † †b) , Macià MUT-PUIGSERVER † †c) , Jordi CASTELLÀ-ROCA †d) , and Josep-Lluís FERRER-GOMILA † †e) , Nonmembers SUMMARY An electronic ticket is a contract, in digital format, between the user and the service provider, and reduces both economic costs and time in many services such as air travel industries or public transport. However, the security of the electronic ticket has to be strongly guaranteed, as well as the privacy of their users. We present an electronic ticketing system that considers these security requirements and includes the exculpability as a security requirement for these systems, i.e. users and the service provider can not falsely accuse each other of misbehavior. The system ensures that either both parties receive their desired data from other or neither does (fair exchange). Another interesting property is reusability. Thanks to reusability the tickets can be used a predefined number of times with the same security as single tickets. Furthermore, this scheme takes special care of the computational requirements on the users side by using light-weight cryptography. We show that the scheme is usable in practice by means of its implementation using mobile phones with Near Field Communication (NFC) capabilities.

A Construction for Providing Reusability to Mobile Phone-Based e-Tickets

Nowadays, the use of electronic tickets in public transport is a reality. Several mobile phonebased e-ticket systems have been proposed so far. Even so, very few of them include reusability in the sense that a single e-ticket allows to make several journeys. Although the identity of users is usually hidden behind a pseudonym, the existing proposals providing reusability allow the system to link all the journeys made with a given e-ticket. In this paper we present a privacy-preserving construction allowing to endow a mobile phone-based e-ticket system with reusability. The privacy of users is proven to be preserved even assuming an internal attacker with full access to all the information managed by the system servers. All the sensitive interactions of a user with the system keep anonymous and unlinkable. Further, as a result of an inspection, the system is only able to determine whether the inspected user is allowed to make the current journey.
