(25. Januar) “This is about uncovering the physics of cyber security and how some of the physical properties of systems have been abstracted to the point that we don’t have a good way to describe the security of the system,” Dr Fu told The Security Ledger in a conversation last week. That is particularly true of sensor driven systems, like those that will populate the Internet of Things. Many types of sensors and devices are vulnerable, from accelerometer and temperature sensors to an ultrasonic proximity sensor, Fu said. “We’re surrounded by sensors and actuators,” he said. While that’s not new, the fact that these sensors are being connected and empowered to make autonomous decisions is, Fu noted.
