Query: Smart Ticket Protection: An Architecture for Cyber-Protecting Physical
  Tickets Using Digitally Signed Random Pattern Markers   In order to counter forgeries of tickets for public transport or mass events,
a method to validate them, using printed unique random pattern markers was
developed. These markers themselves are unforgeable by their physically random
distribution. To assure their authenticity, however, they have to be
cryptographically protected and equipped with an environment for successful
validation, combining physical and cyber security protection. This paper
describes an architecture for cryptographically protecting these markers, which
are stored in Aztec codes on physical tickets, in order to assure that only an
authorized printer can generate a valid Aztec code of such a pattern, thus
providing forge protection in combination with the randomness and uniqueness of
the pattern. Nevertheless, the choice of the signature algorithm is heavily
constrained by the sizes of the pattern, ticket provider data, metadata and the
signature confronted by the data volume the code hold. Therefore, this paper
also defines an example for a signature layout for the proposed architecture.
This allows for a lightweight ticket validation system that is both physically
and cryptographically secured to form a smart solution for mass access
verification for both shorter to longer periods at relatively low cost.
