An evaluation of the vestigial signal defense for civil GPS anti-spoofing
free download

ABSTRACT A receiver-autonomous non-cryptographic civil GPS antispoofing technique called the vestigial signal defense (VSD) is defined and evaluated. This technique monitors distortions in the complex correlation domain to detect spoofing attacks. Multipath and 

Detection strategy for cryptographic GNSS anti-spoofing

Disruption created by intentional generation of fake GPS signals could have serious economic consequences. This article discusses how typical civil GPS receivers respond to an advanced civil GPS spoofing attack, and four techniques to counter such attacks: 

Detecting Converted Speech and Natural Speech for anti-Spoofing Attack in Speaker Recognition

ABSTRACT Voice conversion techniques present a threat to speaker verification systems. To enhance the security of speaker verification systems, We study how to automatically distinguish natural speech and synthetic/converted speech. Motivated by the research on 

A Proposed Navigation Message Authentication Implementation for Civil GPS Anti-Spoofing
free download

ABSTRACT A specific implementation of navigation message authentication (NMA) for civil GPS anti-spoofing is proposed. The notion of GNSS signal authentication is defined in probabilistic terms. This work proposes a practical, backwardcompatible NMA strategy for 

Design of a TOA-based Anti-Spoofing Method for GPS Civil Signal

While the objective of jamming is the denial of the navigation service by masking GPS signals with noise, the objective of Spoofing is to convince you that you are somewhere you are not . Jamming tends to aim at anyone within its coverage area whereas spoofing 

An Anti-Spoofing Technique Using Multiple Textural Features in Fingerprint Scanner

ABSTRACT Large-scale denial of service (DoS) attacks present a grave threat to hosts on the Internet. The use of source IP address spoofing makes the situation much worse. The Implicit Token Scheme (ITS), presented in [9], was demonstrated to be an efficient method to 

SMA: State Machine based Anti-spoofing

ABSTRACT Spoofing attacks are one of the security traits that biometric recognition systems are proven to be vulnerable to. When spoofed, a biometric recognition system is bypassed by presenting a copy of the biometric evidence of a valid user. Among all biometric modalities
