In this article authors present an application of spatial processing methods for GPS spoofing detection and mitigation. In the first part of this article, a spoofing detection method, based on phase delay measurements, is proposed. Accuracy and precision of phase delay estimation is assessed for various qualities of received signal. Spoofing detection thresholds are determined. Efficiency of th...

While biometric authentication has advanced significantly in recent years, evidence shows the technology can be susceptible to malicious spoofing attacks. The research community has responded with dedicated countermeasures which aim to detect and deflect such attacks. Even if the literature shows that they can be effective, the problem is far from being solved; biometric systems remain vulnerab...

The Domain Name System (DNS) is a hierarchical naming system that is built on a distributed database for computers, services, or any other resource connected to the Internet or a private network. It translates the domain names meaningful to humans into the numerical identifiers associated with the networking equipment for the purpose of locating and addressing these devices worldwide [1]. The j...

Although the Internet protocol (IP) has become widely successful, it has led to many security issues. Many of these security issues are related to illegal host access. An address resolution protocol (ARP) spoofing attack is another security issue related to an illegal host access. This paper deals with the prevention of these ARP spoofing attacks. ARP provides dynamic mapping between two differ...

The automatic speaker verification spoofing and countermeasures challenge 2015 provides a common framework for the evaluation of spoofing countermeasures or anti-spoofing techniques in the presence of various seen and unseen spoofing attacks. This contribution proposes a system consisting of amplitude, phase, linear prediction residual, and combined amplitude phase-based countermeasures for the...

Phasor measurement unit (PMU) GPS receiver spoofing has been addressed in the recent literatures. Having spoofed GPS signals, the spoofer can inject bad data into power system control center and consequently the protection system will face serious problems. The existing anti spoofing techniques are all based on GPS signal analysis and are just able to detect spoofing. However, as PMUs are place...

Civilian GNSS signal structures are publicly known and they are received with low power on the earth surface. These make GNSS signals susceptible to spoofing attacks. Hence, the requirement for proper mitigation techniques becomes a must in current and future GNSS receivers for robust, accurate and reliable positioning. This paper proposes a new antispoofing technique using an antenna array in ...

We consider the problem of constructing optimal authentication codes with splitting. New infinite families of such codes are obtained. In particular, we establish the first known infinite family of optimal authentication codes with splitting that are secure against spoofing attacks of order two.

Email spoofing is a critical step of phishing, where the attacker impersonates someone the victim knows or trusts. In this paper, we conduct a qualitative study to explore why email spoofing is still possible after years of efforts to develop and deploy anti-spoofing protocols (e.g., SPF, DKIM, DMARC). First, we measure the protocol adoption by scanning 1 million Internet domains. We find the a...
