Digital signatures to increase security of 2D barcode ticketing systems
2D barcodes, displayed on smartphones, are increasingly used as a “paperless” replacement for various travel or entertainment tickets.
This thesis should analyze the applicability of digital signatures to increase the security of these ticketing systems from the perspective of the ticket issuer.
The student should develop a mobile prototype which is able to create and verify digital signatures on 2D barcodes.
