The profusion of wireless communications in homes, in coffee shops and even on battlefields presents us with fantastic new conveniences -- but also new security problems. Indiana University computer scientist Markus Jakobsson will discuss "stealth" attacks over wireless networks, which can disrupt communications and endanger personal information. One such attack is "denial of service," in which devices are overloaded with so much incoming information they cease functioning properly.
Jakobsson will also discuss "man in the middle" attacks, in which a miscreant invisibly inserts himself into the communication path of two wireless devices, such as cell phones, PDAs, or wireless-enabled laptop computers.
By manipulating software protocols, a man-in-the-middle attacker can silently pass information between two legitimate points while listening in to the wireless conversation, gleaning sensitive personal information or just plain sabotaging the connection. Stealth attacks over wireless networks threaten the security of personal information, online banking and purchasing. Such attacks may also endanger military personnel, who increasingly rely on wireless communications for maneuvering orders and reconnaissance. Defending against stealth attacks in the civilian sector, Jakobsson argues, will require a concerted effort to develop and distribute new software.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
