Abstract:
This work describes an alternative solution for the problem of indoor location in places where the use of GPS devices is either impossible or not precise enough. The new proposal is based on different methods that provide useful information about location in this type of places. In particular, the use of NFC (Near Field Communication) technology in combination with an Inertial Measurement Unit through mobile phones or smartphones allows solving the problem of indoor location without incrementing costs. In particular, an Android application has been implemented to show the applicability of the proposed solution, which adds a layer of security that it is very important to protect the positioning information and avoid the possibility of traceability of the users of the system. To do this, the FourQ elliptic curve has been selected to generate a shared key using the elliptic curve Diffie-Hellman protocol. Then, the generated key is used to cipher all communications through the use of the SNOW 3G stream cipher. The developed system offers promising results.
