PNR otherwise known as Passenger Name Record in the airlines and travel industry is a record in the database of a Computer Reservation system (CRS) that consists of the passenger information for a passenger, PNR code (Booking Reference) and the itinerary for the passenger or a group of passengers travelling together. The PNR code is frequently used to enable online check-in and ticket retrievals for flights and rail travels. The coding system currently used in the travel industry by Amadeus-a foremost Global Distribution System (GDS), for PNR generation is a six (6)-character alphanumeric code comprising four (4) pseudorandom numbers, generated by the rand() function and the first two (2) characters of the passenger’s first name. This coding system has been subjected to a lot of cyber-attacks such that hackers have been able to successfully guess the PNR code time and time again owing to the limitations inherent in the rand() function and overall process of the code generation. They have been able to have access to flight information of passengers, canceling flights in exchange for airline credits which they use to book new tickets, at the expense of the genuine owners of the tickets. This work therefore proposes a cryptographicallysecure booking reference system that is 8-character long with two added layer of security: an implementation specific cryptographically secure pseudorandom number and a security question/answer pair.
