Secure tracking using trusted GNSS receivers and Galileo authentication services

Abstract

This paper describes a secure framework for
tracking applications that use the Galileo signal
authentication services. First a number of limitations that
affect the trust of critical tracking applications, even in
presence of authenticated GNSS signals, are detailed.
Requirements for secure tracking are then introduced;
detailing how the integrity characteristics of the Galileo
authentication could enhance the security of active
tracking applications. This paper concludes with a
discussion of our existing tracking technology using a
Siemens TC45 GSM/GPRS module and future
development utilizing our previously proposed trusted
GNSS receiver.
