The Future Of National And International Security On The Internet, Maurice Dawson, Marwan Omar, Jonathan Abramson, Dustin Bessette Dec 2013

The Future Of National And International Security On The Internet, Maurice Dawson, Marwan Omar, Jonathan Abramson, Dustin Bessette

Maurice Dawson

Hyperconnectivity is a growing trend that is driving cyber security experts to develop new security architectures for multiple platforms such as mobile devices, laptops, and even wearable displays. The futures of national and international security rely on complex countermeasures to ensure that a proper security posture is maintained during this state of hyperconnectivity. To protect these systems from exploitation of vulnerabilities it is essential to understand current and future threats to include the laws that drive their need to be secured. Examined within this chapter are the potential security-related threats with the use of social media, mobile devices, virtual worlds, …


Eavesdropping Attacks In Wireless Ad Hoc Networks Under A Shadow Fading Environment, Xuran Li, Hong-Ning Dai, Qinglin Zhao, Qiu Wang Dec 2013

Eavesdropping Attacks In Wireless Ad Hoc Networks Under A Shadow Fading Environment, Xuran Li, Hong-Ning Dai, Qinglin Zhao, Qiu Wang

Hong-Ning Dai

This paper concerns the eavesdropping attacks in wireless ad hoc networks under a shadow fading environment. Most of previous studies have only concentrated on protecting the confidential communications at both the transmitters and the receivers and little attention has been paid on investigating the eavesdropping behaviors done by the malicious nodes. We therefore investigate the eavesdropping success rate of eavesdroppers equipped with various antenna models under various channels conditions, such as the path loss effect and the shadow fading effect. In particular, we formulate the eavesdropping attack problem with consideration of both simplistic directional antenna models and realistic antenna models. …

An Analytical Model On Eavesdropping Attacks In Wireless Networks, Xuran Li, Hong-Ning Dai, Qinglin Zhao

Hong-Ning Dai

This paper concerns the eavesdropping problem from the eavesdroppers’ perspective, which is new since most of previous studies only concentrate on the good nodes. We propose an analytical framework to investigate the eavesdropping attacks, taking account into various channel conditions and antenna models. Our extensive numerical results show that the probability of eavesdropping attacks heavily depends on the shadow fading effect, the path loss effect and the antenna models; particularly, they imply that using directional antennas at eavesdroppers can increase the probability of eavesdropping attacks when the path loss effect is less notable. This study is helpful for us to …
