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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
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...
