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.

New 3-D wiring technique brings scalable quantum computers closer to reality
19.10.2016 | University of Waterloo
Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
