The convergence of different network types under the same architecture offers the opportunity for low cost multimedia services. The main objective has been the high quality of the provided services. However, considering that older equipment with limited processing capabilities may be present in such environments, a tradeoff between security and service quality is inevitable. Specifically, low r...

A considerable amount of time will be needed before each system in the Internet can convert from Internet Protocol version 4 (IPv4) to Internet Protocol version 6 (IPv6). Three strategies have been proposed by the Internet Engineer Task Force (IETF) to help the transition from IPv4 to IPv6 which are dual stack, header translation and tunneling. Tunneling is used when two computers using IPv6 wa...

Global navigation satellite systems (GNSS) are integral to aviation navigation and precise landings. It will be fundamental to many other safety of life applications such as railway and autonomous vehicles. To truly protect these systems and maintain safety, we need to not just address nominal hazards but also deliberate threats such as spoofing. Many methods have been proposed to address spoof...

A prominent security threat to unmanned aerial vehicle (UAV) is capture it by GPS spoofing, in which the attacker manipulates signal of UAV it. This paper introduces an anti-spoofing model mitigate impact spoofing attack on mission security. In this model, linear regression (LR) used predict and optimal route its destination. On basis, a countermeasure mechanism proposed reduce attack. Confront...

Spoofing attack which easily attack the network and reduce the performance of the network. In this Paper, Spoofing attacks are detected, Finding the number of attackers that masquerade the node identity, Localizing all the attackers node and calculate the speed of a node, by using RSS (received signal strength) for spoofing detection. The number of attacker is determined by clusterbased method....

Biometric systems based on face recognition have been shown unreliable under the presence of face-spoofing images. Hence, automatic solutions for spoofing detection became necessary. In this paper, face-spoofing detection is proposed by searching for Moiré patterns due to the overlap of the digital grids. The conditions under which these patterns arise are first described, and their detection i...

Wireless networks are vulnerable to spoofing attacks, which allows for many other forms of attacks on the networks. A spoofing attack is the most common online attack in which one person or program successfully masquerades as another by falsifying data and thereby gaining an illegitimate advantage, it become more sophisticated defense mechanisms. Although the identity of a node can be verified ...

It is well known that speaker verification systems are subject to spoofing attacks. The Automatic Speaker Verification Spoofing and Countermeasures Challenge – ASVSpoof2015 – provides a standard spoofing database, containing attacks based on synthetic speech, along with a protocol for experiments. This paper describes CPqD’s systems submitted to the ASVSpoof2015 Challenge, based on deep neural ...

A speaker verification system should include effective precautions against malicious spoofing attacks, and although some initial countermeasures have been recently proposed, this remains a challenging research problem. This paper investigates discrimination between spoofed and genuine speech, as a function of frequency bands, across the speech bandwidth. Findings from our investigation inform s...
