Software Defined Radio based Global Positioning System Jamming and Spoofing for Vulnerability Analysis

In recent days, the uses for Global Positioning System (GPS) has increased as now everyone has mobile phones with GPS in it. GPS data is also used in military as it provides the information about location and time which are important factors in various applications. So, the issues of vulnerability for GPS increase with extensive utilization of GPS data by public as well as defense organizations. And when vulnerability increases it becomes easier opportunity for attacker to attack the system. Here two types of attacks are modeled, one where the GPS signal may interfere with the authentic signal and second where the attacker provides wrong information to users about their location by creating forged signal with fake location address and time. The aim of this paper is to achieve successful jamming and spoofing attack using Software Define Radio (SDR). These results can contribute to speed up research on anti-jamming as well as anti-spoofing technology in order to make the GPS more secured for its users and other applications. Some points are also emphasized on anti-spoofing techniques for future research.
