Researchers from the Swiss Federal Institute of Technology in Zurich and the French National Institute for Research in Computer Science and Control
have now developed a scheme for protecting implantable medical devices
against wireless attacks. The approach relies on using ultrasound waves
to determine the exact distance between a medical device and the
wireless reader attempting to communicate with it.  Read the full story [Technology Review]
