Abstract
This work presents a secure novel solution based on inertial measurement units to provide indoor location and positioning in airports. The use of different technologies allows to locate people with precision in this kind of indoor places where the use of the GPS is not possible. The system has been developed thinking in the low cost and in a possible future expansion of this kind of systems to improve the Quality of Service of the users in airports. The use of QR codes and low cost IMU devices through the use of people smartphones ensure this premise. An Android application has been developed to show the applicability and performance of the system. The security in this kind of systems is essential. This kind of systems needs to avoid the traceability of the IMU devices when users are using it. To solve this problem, the FourQ elliptic curve has been used to generate a shared key using…
