Thieves could exploit encryption vulnerabilities, computer scientists warn
A popular radio-frequency ID system that is used to deter car thefts and as a convenience device for the purchase of gasoline can be defeated with low-cost technology, computer scientists from The Johns Hopkins University and RSA Laboratories have determined.
Their findings, described in a new research paper, indicate that the encryption in RFID microchips in some newer car keys and wireless payment tags may not keep thieves at bay. Using a relatively inexpensive electronic device, criminals could wirelessly probe a car key tag or payment tag in close proximity, and then use the information obtained from the probe to crack the secret cryptographic key on the tag, the scientists said. By obtaining this key, lawbreakers could more easily circumvent the auto theft prevention system in that person’s car or potentially charge their own gasoline purchases to the tag owner’s account.
The researchers uncovered the vulnerability while studying the Texas Instruments Registration and Identification System, a low-power radio-frequency security system used worldwide. The researchers said that more than 150 million of these transponders are embedded in keys for newer vehicles built by at least three leading manufacturers. The transponders are also inside more than 6 million key chain tags used for wireless gasoline purchases. The computer security researchers discovered a way that tech-savvy thieves can get around the encryption safeguards in these systems.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
