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.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
Two researchers at Heidelberg University have developed a model system that enables a better understanding of the processes in a quantum-physical experiment...
Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
